You can use synthetic division since the divisor is a linear binomial
x + 3 = 0 so x = -3
-3| 2 3 8
___-6__9_

Answer:
$500
Step-by-step explanation:
The greatest rental time is 5 hours, which is 10 half-hours. The value of C for h=10 is ...
C = 45·10 +50 = 450 +50 = 500
The greatest value in the range for this situation is $500.
Area: 5x² + 7x - 26, Answer C.
To solve the area if the shaded region, let's find the are of the whole figure then find the area of the open rectangle in the center and find the difference of them both.
(3x - 4)(2x + 2)
6x² - 8x + 6x - 8
<span>6x² - 2x - 8
</span>Next, let's solve the area of the open rectangle in the center of the shaded region.
<span>
(</span>x - 6)(x - 3)
x² - 6x - 3x + 18
x² - 9x + 18
Now, let's take the difference between both the areas.
(6x² - 2x - 8) - (x² - 9x + 18)
6x² - 2x - 8 - x² + 9x - 18
5x² + 7x - 26
Answer:
It's C.
Step-by-step explanation:
The red curve pass through the point (0, 1) and also y = 2 when x = 1 , so this is y = 2^x. The inverse is the reflection of f(x) in x = y so the blue curve is y = log2 x.
