Answer: B
Step-by-step explanation:
Domain is x values
Range is y values
Domain you look from left to right. You can see it starts at -3, and it goes all the way to 2. NOT 4 BUT 2!! Since we are looking at the X.
Range.. WE ARE LOOKING AT THE LOWEST POINT!! LOWEST POINT FIRST!1 I cannot stress enough. The lowest y-value is -2, and it's maximum point is 4!
REMEMBER:
DOMAIN = X LEFT TO RIGHT
RANGE= Y LOWEST POINT TO HIGHEST
Answer: Answer choice: [A]: " x⁻ ⁴ " .

Given:
{x ^
;
→ Simplify.
_____________________________________________
Note the following property of exponents:
_____________________________________________
→ (xᵃ) ᵇ = x ⁽ ᵃ * ᵇ ⁾ ; {a ≠ 0 ; b ≠ 0 .} .
_____________________________________________
As such:
_____________________________________________
→ {x ^

= x ^ (

Find:
" .
So: Find: "
" ;
The 2 (two) "7 's " ; cancel out to "1" ;
→ {since: " 7 ÷ 7 = 1 " } ;
And we have:
-4 * 1 = -4 .
So, we have:
" x ⁻ ⁴ " ; which is: Answer choice: [A]: " x⁻ ⁴ " .

Choice: [C} — is also an equivalent; however, the question asks for the "simplest form" — which is: Answer choice: [A].

The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.
![x+x+93=793 \\ 2x=793-93 \\ 2x=700 \\ x=\frac{700}{2} \\ x=350](https://tex.z-dn.net/?f=x%2Bx%2B93%3D793%20%5C%5C%0A2x%3D793-93%20%5C%5C%0A2x%3D700%20%5C%5C%0Ax%3D%5Cfrac%7B700%7D%7B2%7D%20%5C%5C%0Ax%3D350)
The cost of the dryer is $350.

Answer:
We have the system:
y > x^2 - 1
y < (-1/2)*x + 3
To find the solutions of this set we need to graph the solutions range of both sets, and see the intersection between these solution ranges.
How we do it?
Start with the first one.
First, we graph the equation:
y = x^2 - 1
Now because we are using the symbol ">" means that y is smaller than the thing at the right, then the graph of the equation will be with a dashed line (which means that the points on the line are not solutions) and we will shade all the region above the line
For the other inequality we do the same:
First we graph:
y = (-1/2)*x + 3
And because we have the symbol "<" we again use a dashed line, but this time we will shade all the region below the line.
Once we shaded both regions, the region where we have both shades will be the region of solutions for the system of inequalities.
You can see the graph below.
