Answer:
No, the graph does not represent a proportional relationship. It is a straight line, but it does not intersect the point (0, 0). ... It's not proportional because the line does not cross through the origin. Therefore the ratio of x to y will be different for two different points on the line.
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.
Answer:
p=−8
Step-by-step explanation:
Regroup terms.
p
/2 −9=−13
Add 9 to both sides.
p/2 =−13+9
Simplify -13+9 to −4.
p/2=−4
Multiply both sides by 2.
p=−4×2
Simplify 4×2 to 8
