Write the equation of a line that
passes through the following points
:
Point 2: (0,-8)
Point 1: (-3,0)
Answer:
[tex]y = \frac{-8}{3}x - 8[/tex]
Step-by-step explanation:
Solving for the equation of the line with two points:
Let's remind ourself of the slope - intercept formula: [tex]y = mx + b[/tex]
We first have to find the slope of the line. This is found by using the formula :
[tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex]
We have to find the change in y (Δy) and divide it by the change in x (Δx)
We then have to plug in a coordinate given to us, and use the point's x and y value to find the y - intercept
Step 1: SlopeLet's use the slope formula
[tex]\frac{0 - (-8)}{-3 - 0} = \frac{8}{-3}[/tex]
Slope = -8/3
Step 2: Y - InterceptTo find the y - intercept, we'll update our slope - intercept formula with the slope, and plugin a point. Let's use (-3,0)
[tex]y = \frac{-8}{3}x + b[/tex]
[tex]0 = \frac{-8}{3}(-3) + b[/tex]
[tex]0 = \frac{24}{3} + b[/tex]
[tex]0 = 8 + b[/tex]
[tex]b = -8[/tex]
Step 3: EquationLet's input our slope and y - intercept to the equation [tex]y = mx + b[/tex]
Slope = -8/3
Y - Intercept = -8
Equation: [tex]y = \frac{-8}{3}x - 8[/tex]

what is the vertical asymptote for this function?
y=1/x-2
Answer: x = 0
Step-by-step explanation: so x = 0 is the equation of the vertical asymptote, and 0 must be left out of the domain: (−∞,0)U(0,∞) in interval notation.

Step-by-step explanation:
Jill cut 26 apples today. 12 of those apples were red. The rest were green. What is the ratio of red to green apples?
Answer:
7 : 6 is the ratio
Step-by-step explanation:
14 apples were green and 12 apples were red, so divide both terms by 2.
14 ÷ 2 = 7
12 ÷ 2 = 6
Therefore:
14 : 12 = 7 : 6.

Step-by-step explanation:
Micheal-anthony and jocelyn are both running around the track at school. michael-anthony runs 3 miles in 20mins and continues running at this pace for 1 hour. jocelyn runs 4 miles in 30 mins and continues running at this pace for1 hour. how many miles does each person each person run in an hour? who runs faster?
explanation is needed
Answer:
Jocelyn = 8 Miles an Hour
Micheal-Anthony = 6 Miles a Hour
Jocelyn Run Faster than Micheal-Anthony.
Step-by-step explanation:
Important information:
Michael-Anthony runs 3 Miles in 20 Minutes.
Jocelyn Runs 4 Miles in 30 Minutes.
Continues at pace for 1 Hour.
Questions that Need to be Answer:
How many miles does each person each person run in an hour?
Who runs faster?
Explanation/Solution:
So, We know that 1 Hour = 60 Minutes and three 20 minutes equal 60 Minutes also known as 1 Hour..
Since, three 20 minutes equal 1 Hour that means
Micheal-Anthony Run 6 Miles a Hour adding the 20 Minutes equal 9 Miles
Hence, Micheal-Anthony Run 9 Miles..
We know that 1 Hour = 60 Minutes and two 30 Minutes equal 60 Minutes also known as 1 Hour..
Since, two 30 Minutes equal 1 Hour that means
Jocelyn Run 8 Miles a Hour adding the 30 Minutes equal 12 Miles
Hence, Jocelyn Run 12 Miles..
For these Reason, You can tell that Jocelyn Run 8 Miles an Hour and Micheal-Anthony Run 6 Miles a Hour and Jocelyn Run Faster than Micheal-Anthony.

which is a better buy six cans for $7 or 8 cans for $9?
Answer:
8 cans for 9$
Step-by-step explanation:
buy 8 cans for 9$
The 8 cans for $9 is better than six cans for $7.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We need to find better buy six cans for $7 or 8 cans for $9.
Let's find the unit rate of both the quantitites;
six cans for $7
Then one can = 7/6 = 1.16
Therefore, 8 cans for $9.
one can = 9/8 = 1.125
Hence, the 8 cans for $9 is better than six cans for $7.

2) What is the inequality that this graph represents? -15 # 3 6 x
Answer: [tex]y < -\frac{1}{2}x+3[/tex]
This is the same as writing y < (-1/2)x+3
==============================================================
Explanation:
The dashed boundary line goes through (0,3) and (4,1)
Apply the slope formula for those two points
m = (y2-y1)/(x2-x1)
m = (1-3)/(4-0)
m = -2/4
m = -1/2
The slope of the dashed line is -1/2. The y intercept is 3. So we go from y = mx+b to y = (-1/2)x+3 to represent the equation of the dashed line. This is the same as writing [tex]y = -\frac{1}{2}x+3[/tex]
We shade below the dashed line to represent the inequality [tex]y < -\frac{1}{2}x+3[/tex]. Points in the shaded region are solutions to the inequality. One example point is (0,0).
Note that we don't have "or equal to" as part of the inequality sign because we are not including points on the boundary. A solid line, rather than a dashed line, would include points on the boundary.

2. h+17=40 _____
3. n + 75= 155 ____
4. q - 17= 18 _____
Answer:
1. r - 38 = 9
=> r = 9 + 38
=> r = 47
2. h + 17 = 40
=> h = 40 - 17
=> h = 23
3. n + 75 = 155

The distance, d, that an object foto is directly proportional to the square of the time, t, it has been in free fall. An object that has been in free fall for 8 seconds has fallen 1024 feet. Determine the distance the object has fallen if it has been falling for 2 seconds
Answer:
d = 64 feet
Step-by-step explanation:
Given that d is directly proportional to t² then the equation relating them is
d = kt² ← k is the constant of proportion
To find k use the condition t = 8 , d = 1024 , then
1024 = k × 8² = 64k ( divide both sides by 64 )
16 = k
d = 16t² ← equation of proportion
When t = 2 , then
d = 16 × 2² = 16 × 4 = 64 feet

Step-by-step explanation:
First Triangle, this is a 45-45-90 triangle
so the side are 1-1-√2
so if one of the side is 3, you multiply the above by 3
1*3-1*3-√2*3
therefore, a=3√2
Second triangle
this is a 30-60-90 Triangle
so the sides are x-x√2-2x
for this triangle
x√2=6
x=6/√2 --> multiply by √2/√2 --> this gets ride of the √2 in the denominator
x=6√2/4 --> simplify
x=[tex]\frac{3\sqrt{2}}{2}[/tex]
therefore, c=[tex]\frac{3\sqrt{2}}{2}[/tex]
