Answer:

1. x-3=-15
2.2x=-24
3.2x-3=-27

Step-by-step explanation:

Given the following question:

2x+9=-15

To find three equations that have the same solution as the given equation we have to first solve the equation.

2x+9=-15
9-9=0
-15-9=-24
2x=-24
2x\div2=x
-24\div2=-12
x=-12

<u>Equation one:</u>
x-3=-15
-3+3=0
-15+3=-12
x=-12

<u>Equation two:
</u>2x=-24
2x\div2=x
-24\div2=-12
x=-12

<u>Equation three:</u>
2x-3=-27
-3+3=0
-27+3=-24
-24\div2=-12
x=-12

Hope this helps.

Which function represents a reflection of f(x) = 5(0.8)^x across the x-axis?
Vikki [24]

Answer: The correct option is second.

Explanation:

The given function is,

f(x)=5(0.8)^x

If we graph a function is f(x), then its coordinates is defined as (x,f(x)).

When the graph of f(x) is reflect across the x-axis, then the the x-coordinate remains the same and the sign of y-coordinate is changed. It means after reflecting across the x-axis,

(x,y)\rightarrow(x,-y)

The given given equation can be written as,

y=5(0.8)^x

To find the equation of the graph after reflection across the x-axis multiply both sides by -1.

-y=-5(0.8)^x

Because f(x)=y and g(x)=-y.

g(x)=-5(0.8)^x

Therefore the second option is correct and the graph of both function is given below.
