Iteru [2.4K]

Answer:

Cereal B

Step-by-step explanation:

Given are two different rates for cereals A and B.

as Cereal A: 15oz for $2.95 or Cereal B: 32oz for $5.95

As such we cannot compare unless we make it unit rate for same number of units

Let us find unit oz rates

Cereal A per oz= \frac{2.95}{15} =0.1967dollars

Cereal B per oz = \frac{5.95}{32} =0.1859dollars

Comparing unit rates per ounce,

we find that Cereal B per oz is lower.

Answer is Cereal B.

What is the value of the function f(x)=10x+2?
Nookie1986 [14]

Answer:

2 if x=0

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type.

f(x) = 10x + 2

Replacing f(x) with y

y = 10x + 2

If x = 2,

y = 10(0)+2

y=2
