They are not proportional because they do not have a constant ratio. If the data on the graph shows a curved line, it is not constant and is not proportional.

Find the x and y intercept of y= -2(x-3)^2+4

Neko [114]

Y intercept occurs when x = o so it is -2(0-3) + 4 = -2

x intercepts:-

-2(x - 3)^2 + 4 = 0

(x - 3)^2 = -4/-2 = 2

x - 3 = +/- sqrt2

x = 3 + sqrt2 and 3- sqrt2

Joshua can purchase tile at one store for $0.99 per tile but he he will have to rent a tile saw for $25 at another store he can

natita [175]

Answer: the number of tiles will be 49

Step-by-step explanation:

Let x represent the number of tiles that Joshua can buy at either stores.

one store for $0.99 per tile but he he will have to rent a tile saw for $25. Let the total cost of buying x tiles in this store be y. Therefore

y = 0.99x + 25

At another store, he can buy a tile for $1.50 per tile and borrow a tile saw for free. Let the total cost of buying x tiles in this store be z. Therefore

z = 1.5x

To determine the number of tiles for which both costs will be the same, we will equate y to z. It becomes

0.99x + 25 = 1.5x

1.5x - 0.99x = 25

0.51x = 25

x = 25/0.51

x = 49
