Write a polynomial function in factored form with zeros at −2, 5, and 6.

1 answer:

3 0

The root -2 leads to the factor (x+2). The other 2 factors are (x-5) and (x-6).

Then the poly is f(x) = (x+2)(x-5)(x-6).

MANUFACTURING A shoe manufacturer spends $2.50 to make sandals and $4 to make running shoes. During a typical month, they spend

jonny [76]

Answer:

200 pairs of sandals

Step-by-step explanation:

Represent the sandals with x and the running shoes with y.

In a typical month:

$Total = 2500$

In April

$Total = 3000$

Required

The number of sandals in a typical month

In a typical month:

If 1 sandal costs 2.50, then x costs 2.50x

If 1 running shoe costs 4, then y costs 4y

The total is:

$2.50x + 4y = 2500$

In April:

If 1 sandal costs 2.50, then 2x costs 5x ---- we used 2x because the pairs is doubled

If 1 running shoe costs 4, then y costs 4y

The total is:

$5x + 4y = 3000$

The equations are:

$5x + 4y = 3000$

$2.50x + 4y = 2500$

Subtract

$5x - 2.50x + 4y - 4y = 3000 - 2500$

$2.50x = 500$

$x = \frac{500}{2.50}$

$x = 200$

Paulo’s grandfather gave him a collection of 20 coins. Each month Paulo adds 4 coins to his collection. Which inequality can be

Phoenix [80]

Answer:

$4m+20>50$

Step-by-step explanation:

Let m represent the amount of months that has passed.

Paulo started out with 20 coins.

Each month, he adds four more coins to his collection.

Therefore, the amount of coins added after m months will be given by 4m.

So, the amount of coins Paulo has total after m months can be given by:

$4m+20$

We want to know when Paulo will have "more than" 50 coins in his collection. Therefore, we will use the "greater than" sign. Thus, our inequality will be:

$4m+20>50$
