$\boxed{\bold{One \ Solution}}$

Step-by-step explanation:

<u>Solve equation to find answer(s)</u>

<u></u>

Combine: 6z - 3z = 3z

$\bold{3z-7=-2+3}$

Add: -2 + 3 = 1

$\bold{3z-7=1}$

Add 7 to both sides:

$\bold{3z-7+7=1+7}$

Simplify:

$\bold{3z=8}$

Divide both sides by 3:

$\bold{\frac{3z}{3}=\frac{8}{3}}$

Simplify:

$\bold{z=\frac{8}{3}}$

The container that holds the water for the football team is 7/10 full. After pouring out 5 gallons of water, it is 1/2 full. How

Shtirlitz [24]

7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===

Which exponential function is represented by the graph?

Anna [14]

Answer:

Step-by-step explanation:

Let's solve this using our formula for exponential functions:

$y=a(b)^x$ where a is the initial value and b is the growth/decay rate. We will fill that equation in with 2 of the coordinates on the graph and come up with the values for both a and b. (0, 3) and (1, 6):

$3=a(b)^0$ . Anything raised to the power of 0 is 1, so that means that

a = 3. We will use that value along with the x and y from the second coordinate to solve for b:

$6=3(b)^1$ . b to the first is just b, so our equation is

6 = 3b and

b = 2.

Our equation then is

$y=3(2)^x$ , the third choice down.
