Answer:
(7^2)^2
7^2 / 7^-2
Step-by-step explanation:
7^-2 * 7^6
We know that a^b * a^c = a^ (b*c)
7^ (-2+6)
7^ 4
This is also 7^2 ^2
We also know that
7^2 / 7^-2
We know a^b / a^c = a^ (b-c)
7^(2 - -2) = 7^ (2+2) = 7^4
Answer:
C. y = -x + 68
Step-by-step explanation:
First, remember that slope-intercept form is y = mx + b, where m = slope, b = y-intercept.
We know that the slope is negative. Unfortunately, all the answers have negative slopes, so we can't rule anything out.
Let's look at the y-intercept. It looks like it's around 60, a little higher; 68 and 65 are both good options. It's clearly not 55 or 100, so eliminate choices D and B.
Now let's look at the slopes - it looks like the slope is closer to than 2x. Check out the attached graph - pick points at random and check which graph seems to match them most often!
