H^-16/h^x=1/h^24 can someone help me please
Basile [38]

Given:

Consider the equation is

\dfrac{h^{16}}{h^x}=\dfrac{1}{h^{24}}

To find:

The value of x.

Solution:

We have,

\dfrac{h^{-16}}{h^x}=\dfrac{1}{h^{24}}

Using properties of exponents, we get

h^{-16-x}=h^{-24}       [\because \dfrac{a^m}{a^n}=a^{m-n},a^{-n}=\dfrac{1}{a^n}]

On comparing both sides, we get

-16-x=-24

Add 16 on both sides.

-x=-24+16

-x=-8

Multiply both sides by -1.

x=8

Therefore, the value of x is 8.

The seventh grade choir sold pizzas as a fundraiser. The choir teacher created the graph below for the students.
frez [133]

Answer:

C

Step-by-step explanation:

We are trying to find the profit for every pizza sold. Since looking at the x axis, the point in which its x coordinate is 1 cannot be easily identified. Thus, we shall derive the answer using a point that can be easily identified.

We observe that the two points, (10,12) and (20,24) sits nicely on the graph. I will be using the first coordinate above to derive the answer.

For every 10 pizzas sold, $12 of profit is made.

10 pizzas ----- $12 profit

1 pizza ----- $12 ÷10= $1.20

Hence, the unit rate of profit for the pizzas is $1.20 per pizza.

GCF of 6x and x pls show work
vesna_86 [32]
GCF means the term(s) that 6x and x have.
The GCF is x because:
1. Using multiplication: 6x * x = 6x^2
becomes x(6+x) = 6x^2
GCF is x.

Good luck to you!
