Choose the graph that represents a function.
noname [10]
A relation is not a function if a given input corresponds to two or more outputs.

Only selection B is a function, as it is the only one that doesn't have points one on top of another (same x, multiple y-values).

A rectangular picture frame is 5 inches wide and 10 inches tall. You want to make the area 6 times as large by increasing the le
kap26 [50]

Answer:

5 inches

Step-by-step explanation:

(5 + x)(10 + x) = 6x²

x² + 15x + 50 = 6x²

5x² - 15x + 50 = 0

x² - 3x + 10 = 0

(x - 5)(x + 3) = 0

x = 5, x = -3

We want x to be positive, so x = 5.

Thus, each dimension must be increased by 5 inches.
