x - 2 + 6x + 4 = 8x - 2
7x + 2 = 8x - 2
2 + 2 = 8x - 7x
4 = x <===
Answer:
x = -y
or
-y = x
Step-by-step explanation:
since you reflect it over the x axis, the y changes to a negative
Answer:
Fruits: 107
Vegetables: 56.5
Step-by-step explanation:
Average is found by adding all of the values together and then dividing by the number of values that there are.
So for fruits, you would do 62+55+49+50+98+328 and then divide that whole thing by six.
Same for veggies, 34+122+57+21+79+26 with the answer divided by six.

f(x) = x² + 14 g(x) = x - 2 -1 ? I think it means evaluate when x = -1
Find (f(x) + g(x)) when x = -1
(f(x) + g(x)) = [ ( x² + 14) + (x - 2)] insert f(x) and g(x)
= [ x² + x + 14 - 2] add like the term
(f(x) + g(x)) = x² + x + 12
(f(-1) + g(-1)) = (-1)² + (-1) + 12 evaluate at x = -1
= 1 - 1 + 12
= 12
