Answer:
The equation of the line is y = 3/2x + 5/2
Step-by-step explanation:
To find the equation of this line, start by using the two points with the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 1)/(1 - -1)
m = 3/(1 + 1)
m = 3/2
Now that we have the slope, we can use that and either point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = 3/2(x - 1)
y - 4 = 3/2x - 3/2
y = 3/2x + 5/2
Answer:
M(B(h))=78.18025h
Step-by-step explanation:
First we have the following equations:
L(h) = 28.75h eq. 1
B(L) = 1.78L eq. 2
M(B) = 1.43B eq. 3
To find the selling price based on the estimated number of hours, we need to start replacing equation 1 in equation 2 as:
B(L) = 1.78*B
B(L(h)) = 1.78*(28.75h)
B(L(h)) = B(h) = 51.175h eq. 4
Finally, if we weplace equation 4 in equation 3, we get:
M(B) = 1.43B
M(B(h)) = 1.43*(51.175h)
M(B(h)) = 73.18025h
So, the composite function that can be used to find the selling price for the labor portion of a bid based on the estimated number of hours is:
M(B(h)) = 73.18025h

that is my awnser but have someone else double check it just to be shure
Answer: 
Step-by-step explanation:
Given
3 cups of milk are required for 4 cups of flour
Suppose there are x cups of milk and y cups of flour
So, according to the question
The above equation represents the linear equation.
For this case we have:
The division given by:
102 ÷ 3 = 34
To verify its result we use multiplication as a reverse operation, that is:
We multiply the quotient by the divisor and its result must be the dividend.
So:
Answer:
Multiplication,
