Answer:
D
Step-by-step explanation:
7 is it because it is positive
I think you're missing a bit of the question. If her savings can be modeled by x...?
Since f(x) is up and down, simply decrease the overall equation by 2 to get 2sqrt(x+3)+3 instead of +5. To move it 5 to the right, we have to do something kind of weird, which is subtract 5 from (x+3) instead of add 5 to get
2sqrt(x-2)+3.
The sum is 12x3+18x2-10x+8

Step-by-step explanation:
<u>Step 1: Define Equation</u>
8(2x + 5) = 16x + 40
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 8: 16x + 40 = 16x + 40
- Subtract 40 on both sides: 16x = 16x
- Divide 16 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>.
∴ <em>x</em> has an infinite amount of solutions.
