Answer:
m=2
Step-by-step explanation:
We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.
Therefore, substituting the values of x=3 and y=-1 in the given line, we have,
⇒
⇒
⇒
⇒
⇒
Hence,the value of m will be equal to two.
3. Divide by 5
4. Add 12
5. Multiplying by -8
6.subtracting by -6
Solution: The test score that the teacher should expect from a student who did not attend her course is 37.
<u>Explanation:</u>
The teacher's equation for the line of best fit is 
We know the equation for the line of the best fit is:

Where:
is slope of the equation. It represents the rate of change in y as one unit change in x.
is the intercept. It represents the expected mean value of y when all x=0.
Therefore, in the given teacher's equation, the slope is 0.7 and intercept is 37.
Here the intercept means the average score of student who who did not attend her course.
Therefore, the test score that the teacher should expect from a student who did not attend her course is 37.
C. million or 500,000,000
d.thousands or 30,000
and the first one is good and the second one for the million you wrote all the zeros right so it should look like 80,000,000
Answer:
Theresa needs 44 pieces of woods.
Step-by-step explanation:
Given:
Length of wood required to fence = 233 feet
Length of the wood = 11 feet
Number of pieces of wood Samuel needs = 22 pieces.
We need to find number of pieces of wood required by Theresa.
Solution:
Now Given:
Theresa has twice as many feet of wood as Samuel.
So we can say that;
Number of pieces of wood Theresa need is equal to 2 multiplied by Number of pieces of wood Samuel has.
framing in equation form we get;
Number of pieces of wood Theresa need = 
Hence Theresa needs 44 pieces of woods.
