We have a
number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that
begins in -3 and closes in 8, that is,
<em>takes values from -3 to 8</em>. In a mathematical language this is given by
the following statement:
</span>
![x \in [-3,8]](https://tex.z-dn.net/?f=x%20%5Cin%20%5B-3%2C8%5D)
<span>
</span>
F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
Answer: -4
Well I believe the correct equation would be 3x-y+7 because the y- intercept is 7 which is positive. That could only mean that the answer with a positive 7 is correct.
hope this helps!!

Answer:
9x^4-36x^3-27x^2
Step-by-step explanation:
assuming those are exponents
PRT+PRT=Total Interest
0.03x+0.11(2x)=104.5
0.25x=104.5
x=418
x+2x, 418+2(418)=1254
Total Investment=1254 dollars
