Answer:

The answer is C.

Step-by-step explanation:

You have to use Ditributive Law,

a(m + n) = am + an

So for this question :

(3x - 2)(x + 5)

= 3x(x) + 3x(5) - 2(x) - 2(5)

= 3 {x}^{2}  + 15x - 2x - 10

= 3 {x}^{2}   + 13x - 10

If f(x)=-7x-3 and g(x)=√x-16 what is (f °g)(-2)
schepotkina [342]

Answer:

Not possible

Step-by-step explanation:

The notation (f °g)(-2) means f(g(-2)). You will substitute -2 into g(x) then substitute the value or equation that results into f(x).

g(-2) = √x - 16 = √-2 - 16

This is not possible because the value of -2 cannot be found in a square root. Square roots do not compute real roots for negative numbers.

Svetllana [295]
Hb=3.5, hd=2.25, hb+hd=7, 

From the third, we can say hb=7-hd and we are told that:

3.5hb+2.25hd=19.5  using hb found above in this equation gives you:

3.5(7-hd)+2.25hd=19.5

24.5-3.5hd+2.25hd=19.5

-1.25hd=-5

hd=4

Carmen bought 4 hotdogs.

A student purchases school supplies at a store where the sale tax is 7%. The pre-tax price of the supplies is $48. What is the t
Alenkasestr [34]

Solution: We are given:

Sales tax =7\%

The pre-tax price of the supplies = 48

We have to find the total cost of the supplies.

We first need to find the sales tax on the price of supplies. The sales tax amount is:

7\% of 48=0.07 \times 48=3.36

Therefore, the total cost of the supplies = pre-tax price of the sales + sales tax amount

                                                                  =$48 + $3.36

                                                                  =$51.36
