Roberto buys 15 balls for 300. how much will you pay for 10 balls?

$200 (or whatever the currency is since it is not specified here)

Step-by-step explanation:

We can create a proportion for this

$300/15 balls = $x/10 balls

Cross-multiplication: 15x = 3000

Divide: x = $200

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
