What is the equation of the line that is perpendicular to y = -2/3x + 4 and that passes through (–2,–2)?
y = 3/2x - 3/10
y = 3/2x - 5
y = 3/2x + 1
y = 3/2x - 2/3
Answer: y = 3/2x + 1
Step-by-step explanation: For a perpendicular line, take the reciprocal of "m" and reverse the sign.
- 2/3 becomes +3/2
Then substitute the y and x values of the given coordinate into the equation and solve for "b"
y = mx + b
-2 = 3/2(-2) + b
-2 = -3 + b
-2 +3 = b
+1 = b Substitute for b in y = (3/2)x + 1

Answer:
a. the measure of angle A is 113 degrees
the measure of angle B is 67 degrees
Step-by-step explanation:
Remember, linear pairs have a sum of 180 degrees when added. So, if you add your angle measures and set it equal to 180, then you just need to solve from there.
7x-13+3x+13=180
combine like terms
(7x+3x)+(-13+13)=180
10x+0=180
10x=180
divide both sides by 10 to isolate x
x=18
now that you have x, plug it into your angle measures
m<a: 7(18)-13
126-13
113
m<b: 3(18)-13
54+13
67

Answer:
The equality is not true.
Step-by-step explanation:
[tex](4^2 +24) = |(3 - 7) - 16|[/tex]
[tex](16 +24) = |(3 - 7) - 16|[/tex]
[tex]40 = |(3 - 7) - 16|[/tex]
[tex]40 = |(- 4) - 16|[/tex]

Find the area of the semicircle please .
Answer:
39.25
Step-by-step explanation:
the formula is a = (3.14 × [tex]r^{2}[/tex]) / 2
the equation is a = (3.14 ×[tex]5^{2}[/tex]) / 2
5 is the radius
1. [tex]5^{2}[/tex] = 25
2. 3.14 × 25 = 78.5
3. 78.5 / 2 = 39.25
I hope this helped! :)
Answer:
12.5π or 39.25
Step-by-step explanation:
10 is diameter, we first find the radius which is 10/2 = 5 and so we know the area formula of the circle is πr^2 so 5^2 is 25 and then there's a π at the end so 25π, but it's a semicircle so 25π/2 which is 12.5π, if it's in base 10 (decimal form) then simply do 12.5 x 3.14 = 39.25

Josh but a total of 30 cans of cola and root beer. There were twice as many cans of cola is cans of root beer. How many cans of color did he buy?
Answer:
20
Step-by-step explanation:
start by using system of equations
x = cola
y = root beer
x + y = 30
x = 2y
now either use substitution or elimination. for me, substitution is easier.
the second equation already has one variable isolated ( x ) so, plug that into the first equation.
2y + y = 30
y = 10
now plug your answer into the original equation.
x + 10 = 30
x = 20
hope this helps :)
When do you use a Vertex Form y=a(x – h)2 + k ? What information do you get from a Vertex Form?
Please tell me
y = a(x - h)² + k is the vertex form of an equation of a parabola with vertex (h,k)
We get the coordinates of the vertex of parabola from that form: (h, k)
We also know if the parabola goes up or down: a>0 or a<0
We can tell how many roots has the equation:
(a>0 and q>0) or (a<0 and q<0) ⇒ no roots
a≠0 and q=0 ⇒ one root: x₀=p
(a>0 and q<0) or (a<0 and q>0) ⇒ two roots
We can also determine the roots (if they exist):
a(x - h)² + k = 0
a(x - h)² = - k
(x - h)² = - k/a
x - h = √[-k/a] ∨ x - h = - √[-k/a]
x = √[-k/a] + h ∨ x = - √[-k/a] + h
Usually you use this form to find the equation of parabola when you have got given the vertex and some other point from that parabola.

A coordinate plane with a line passing through (negative 3, 0) and (0, 2).
A coordinate plane with a line passing through (0, 2) and (2, negative 1).
A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).
Answer:
graph 1
Step-by-step explanation:
Graph using table of values
x y
2 -2/3
1 -4/3
0 -2
they are all on that graph
The graph represents a line with a slope of -2/3 and a y-intercept equal to that of the line y = 2/3x – 2 is A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).
What is slope?The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx.
What are intercepts?Using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.
According to the question
Represents a line with a slope of -2/3
i.e ,
m = -2/3
y-intercept equal to that of the line
y = [tex]\frac{2}{3}x-2[/tex]
i.e ,
at y-intercept , x = 0
y = -2
Now, Putting value in standard form of line
y = mx + c
-2 = 0 + c
c = -2
now , substituting the values of m and c in standard form of line
y = mx + c
y = [tex]\frac{-2}{3}x-2[/tex] --------- (equation of graph )
Now ,
x y
0 -2
3/2 1
3 0
Only option 4 have these points
Hence, The graph represents a line with a slope of -2/3 and a y-intercept equal to that of the line y = 2/3x – 2 is A coordinate plane with a line passing through (negative 3, 0) and (0, negative 2).

Gepetto, a puppet maker, can produce 15 new puppets per week. He already has 25 completely finished puppets in storage. We want to write an equation to model the relationship between the number of puppets available for sale and the number of weeks. a) What is the slope of your model? (Hint: you are looking for a rate!) b) What is the y-intercept of your model? (Hint: this is also sometimes called the “starting value.”) c) Write an equation in slope-intercept form expressing the relationship between the number of puppets available for sale and the number of weeks. Make sure to define your variables! d) Use your equation to predict how many puppets would be available for sale after seven weeks. e) Use your equation to determine how many weeks it would take Gepetto to fulfill an order for 220 puppets.
Answer:
a) 15
b) 25
c) p = 15w + 25, where p is puppets and w is weeks
Step-by-step explanation:
a) Gepetto makes 15 puppets a week, so as the weeks increase by 1, puppets increases by 15, making the slope 15
b) Gepetto started out with 25 puppets. This means that when x = 0 (0 weeks), there will be 25 puppets already
c) The slope and y-intercept were incorporated into an equation in slope-intercept form.

240 is 75% of what number?
Answer:
320Step-by-step explanation:
Let the unknown number be x
[tex]75 \% \times x = 240 \\ \frac{75x}{100} = 240[/tex]
Cross Multiply
[tex]75x \times 1 = 100 \times 240 \\ 75x = 24000[/tex]
Divide both sides of the equation by 75
[tex] \frac{75x}{75} = \frac{24000}{75} [/tex]
Simplify
[tex]x = 320[/tex]
Answer:
320
Step-by-step explanation:
you would do [tex]\frac{75}{100}[/tex]*x=240
then you would multiply both sides by 100 and then divide both sides by 75 which woud give you x=240*[tex]\frac{100}{75}[/tex]
which would give you [tex]\frac{24000}{75}[/tex]=x
which then simplifies down to 320

Which polynomial function gets larger and larger in the negative direction as x gets
larger and larger in the negative direction?
a. f(x) = 5x2 – 2x + 1
b. f(x) = 6x3 + 4x2 – 15x + 32
c. f(x) = 7x4 – 2x3 + 3x2 + 8x – 10
d. f(x) = 8x6 + 1
Given:
x gets larger and larger in the negative direction.
To find:
The polynomial function which gets larger and larger in the negative direction.
Solution:
In options a, c and d, degree of polynomials are even and leading coefficient is positive. So,
[tex]f(x)\to \infty\text{ as }x\to -\infty[/tex]
In option b, degree of polynomial is odd and leading coefficient is positive. So,
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
Therefore, the function in option b, [tex]f(x)=6x^3+4x^2-15x+32[/tex] gets larger and larger in the negative direction as x gets larger and larger in the negative direction.
Hence, the correct option is b.
We want to see which polynomial function gets larger and larger as the variable increases in the negative direction. We will see that the correct option is d: f(x) = 8x^6 + 1
Here you need to remember two things.
As the larger the exponent is, the faster the polynomial grows.
When we evaluate a negative number in an even exponent, the outcome is always positive.
Then the polynomials that get larger and larger as x increases in the negative direction are all the polynomials with a even leading exponent, particularly, the one that increases faster is the one with the largest leading exponent, which is:
d. f(x) = 8x^6 + 1

Robert believes the lines graphed at right are perpendicular, but Mario is not convinced. What is the slope of each line? Explain how you know whether or not the lines are perpendicular.
Answer/Step-by-step explanation:
An easy way to be sure two lines are perpendicular is if the product of both slopes equals -1.
That is: [tex] (m_1)(m_2) = -1 [/tex]. Where, m1 and m2 are slopes of both lines respectively.
Let's find the slope of the both lines.
Slope of the line that slants upward from left to right using coordinates (0, 0) and (2, 2) of two points on the line:
[tex] m_1 = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{2 - 0} = \frac{2}{2} [/tex]
[tex] m_1 = 1 [/tex]
Slope of the line that slants downwards from left to right using coordinates (2, 2) and (0, 4) of two points on the line:
[tex] m_2 = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 2}{0 - 2} = \frac{2}{-2} [/tex]
[tex] m_2 = -1 [/tex]
Find the product of both slopes
[tex] (m_1)(m_2) = (1)(-1) = -1 [/tex]
Therefore, we know the lines are perpendicular because [tex] (m_1)(m_2) = -1 [/tex].

A car is driving down from the top of a Colorado mountain. The elevation is 13,500 feet. Every minute of driving, the car's elevation decreases by 150 feet. Let x be the time in minutes that the car has been driving down the mountain , E(x) = -150x+13,500. Evaluate E(5), and explain the meaning of the answer in terms of the car.
Answer:
Step-by-step explanation:
Given the rate at which the car elevation decreases expressed by the function
E(x) = -150x+13,500 where x is in minutes.
To evaluate E(5), we will substitute the variable x = 5 into the function as shown;
E(5) = -150(5)+13,500.
E(5) = -750+13,500.
E(5) = 13500-750
E(5) = 12750
This means that after 5minutes, the car elevation has decreased by 12,750feet
