Step-by-step explanation:
2.5x+12=32
We move all terms to the left:
2.5x+12-(32)=0
We add all the numbers together, and all the variables
2.5x-20=0
We move all terms containing x to the left, all other terms to the right
2.5x=20
x=20/2.5
x=8
Distance equals end minus start
(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)
(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20
So the distance between the two points is 20
I hope this helps
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
Answer:
x=12
Step-by-step explanation:
2x-8=16(add a to both sides)
2x=24(divide by 2)
x=12
