Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-4,1) m=4
The equation of the line is ?
Answer:
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Step-by-step explanation:
Given
The point = (-4, 1)m = 4Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
here:
m = slope(x₁, y₁) = pointsubstituting the values m = 4 and the point (-4, 1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-1 = 4(x-(-4))[/tex]
Thus,
An equation in point-slope form of the line that passes through the given point and with the given slope m = 4 will be:
[tex]y-1 = 4(x-(-4))[/tex]
Note: It can further be simplified
[tex]y-1=4\left(x+4\right)[/tex]
Add 1 to both sides
[tex]y-1+1=4\left(x+4\right)+1[/tex]
[tex]y=4x+17[/tex]
Olivia baked 45 mini-loaves of banana bread to be sliced for snacks at a craft fair. She will place an equal number of loaves in 6 different locations. What if Olivia wants to put only whole loaves at each location? How many loaves will be at each location?
Answer:
7 whole loaves of bread.
Step-by-step explanation:
Since there are total of 6 locations and each location needs to have the same number of whole loaves of bread we simply need to divide the number of mini-loaves of banana bread by the number of locations like so...
45 / 6 = 7.5
As we can see by the mathematical expression above 45 loaves of bread can be divided into 6, giving each location 7.5 loaves of bread but since each location needs only whole loaves then that would mean that each location would get 7 whole loaves of bread.
What determines the pitch of a sound? PLEASE HELP MEH!!
the decibel level
the frequency of vibrations
the amplitude
the medium
Answer:
Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.

show work what is the gcf of 12x^2 and 15x^3
Hey there! I'm happy to help!
The greatest common factor is the largest factor that both numbers contain. Let's look at the factors of these terms.
12x²: 1, 12, 2, 6, 3, 4, x, x
15x³: 1, 15, 3, 5, x, x ,x
We see that both of these numbers contain a 3 and 2 x's, so our GCF would be 3x².

On Saturday, Alicia ran 2 miles. This was 0.3 miles farther than Henry ran. Write and solve an
an addition equation to find out how many miles Henry ran.
Answer: a - 0.3.
Step-by-step explanation;
Let a represent the number of miles that Alicia ran. The equation will be this: a - 0.3. You will subtract 0.3 from the number of miles that Alicia ran because her amount is 0.3 miles farther than what Henry ran.
The position data for line 1 was recorded in 1-second intervals. Draw a graph with distance on the y-axis and elapsed time on the x-axis. Reference all distance and time measurements to dot 1. To plot a point, use the circle tool. To draw a line between points, use the line tool. To move a point or line, use the select tool.

Here is a list of ingredients for making 12 small cakes. 108 g margarine 180 g sugar 200 g plain flour 1 teaspoon baking powder 2 eggs. Joe is going to make 24 of the small cakes. Determine how much margarine he will need. Write your answer in a complete sentence.
Answer:
216g of margarine
Step-by-step explanation:
From the above question:
12 small cakes required 108g of margarine
If he would be making 24 of the small cakes, hence, that would be calculated as:
12 small cakes = 108g of margarine
24 small cakes = x
Cross Multiply
12 × x = 24 × 108g
x = 24 × 108g/12
x = 216g of margarine
Therefore, he would need 216g of margarine to make 24 of small cakes

Is there anybody from the online schooling called BUZZ? that can help me out at all?
Have a great day! Merry Christmas! <3
PLEASE ANSWER ASAP! LOOK AT THE PIC ATTACHED: (please show work!)
Answer:
Answer is B
Step-by-step explanation:
Remember, perpendicular lines have opposite slopes. In order to do this, you just need to flip the sign (Change it to the opposite. For example, if it is 3, it would be -3), and change the slope to its reciprocal (For example, if it is 3, it would 1/3). Finally, since the equation is y = 1/2x + 10, the slope would change to -2x... so your answer is B
what’s the quotent of -3/8 and -1/4
Answer:
1.5
Step-by-step explanation:
-3/8=-0.375
-1/4=-0.25
the negatives cancel each other out so it is 0.375/0.25
.25 goes into .375 1.5 times, so the answer is 1.5

Write an equivalent expression for 2(1.7x + 3.3) + 5(2.6x + 1.4) by combining like terms
Answer:
16.4x + 13.6
Step-by-step explanation:
Equivalent Expressions
Algebraic expressions can be given in different forms when applying properties of the basic operations.
The given expression is:
2(1.7x + 3.3) + 5(2.6x + 1.4)
Multiplying both parentheses by the outer factor:
3.4x + 6.6 + 13x + 7
Combining like terms:
16.4x + 13.6
The original and the final expressions are equivalent because they produce the same results

Find the perimeter of a square garden if it’s area is 1369m2?
Answer:
Step-by-step explanation:
The area formula for a square is
[tex]A=s^2[/tex] where A is the area and s is a side measure. In a square, this side measure is the same (because all 4 sides in a square are the same). Therefore, our formula becomes:
[tex]1369=s^2[/tex]
Take the square root of both sides to find that a side measures 37 m.
The perimeter of a square is to add all 4 sides together (or to multiply the one side by 4):
4 * 37 = 148 m
