Answer:
-16/45
Step-by-step explanation:
8/15 x (-2/3)
multiplying a positive and a negative equals a negative
-8/15 x 2/3
multiply the fractions
-16/45
Y2-y1/x2-x1
5-(-3)/(-6-(-1))
8/-5
-8/5 is the slope
F’= 7+2x, plz mark my answer~
a. Write and graph an equation in two variables that represents the total cost of ordering the shirts.
For this case, the first thing we must do is define variables:
c = total cost
x = x number of shirts.
The equation that adapts to the problem is:
c (x) = 10x + 20
Answer:
c (x) = 10x + 20
b. Choose an ordered pair that lies on your graph in part (a). Interpret it in the context of the problem.
Let's choose the next ordered pair:
(x, c (x)) = (0, 20)
We verify that it is in the graph:
c (20) = 10 (0) + 20
c (20) = 20 (yes, it belongs to the graph).
In the context of the problem, this point means that the cost per shipment is $ 20
Answer:
(0, 20)
Cost per shipment is $ 20
To solve this equation, you will need to set up a proportion where you set two fractions equal to each other.
Let x = the unknown amount of milk
You would then crossmultiply and solve for x.
8x = 400(6)
8x = 2400
x = 2400/8
x = 300
You will need 300 mL of milk to make 6 pancakes if you previously needed 400 mL to make 8 pancakes.
