1 answer:

Is this what your asking: (x+3)(x^4 - x^2 + 5)

If you are then:
(x+3)(x^4 - x^2 + 5)
= (x+3)(x^2 + 5)
= x^3 + 3x^2 - 5x - 15

Looks kinda confusing but yh... Anyway, hope it helped :)

David has been tasked with tracking the number of bagels sold (y) at freddy's 24-hour bagel shop from 12: 00 am (*= 0) to 12: 00

mafiozo [28]

Answer:

53 bagels

Step-by-step explanation:

The number of bagels, y sold is a function of the square of the time (x) plus 4.

Therefore:

$y=x^2+4$

Number of Hours from 12.00 am to 7:00 am =7

At x=7

The number of bagels sold,

$y=7^2+4\\=49+4\\=53\\$

The bagel shop sold 53 bagels from 12: 00 am to 7: 00 am.

Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42.

nata0808 [166]

x = 24

Step-by-step explanation:

y₂ - y₁

42 - 21 = 21

x + 21

3 + 21 = 24

So when y increases by 21, so does x.

x = 24

Seth bought a 12 - ounce jar of peanut butter for $3.60. What is the unit price?

allochka39001 [22]

Since the jar is 12 ounces, we want to find the price when it is one ounce. We do this by dividing the price, $3.60, by 12:

3.60/12 = 0.3

So, the answer is $0.30/oz, or (B).
