The tree is 7.5ft because it's shadow is half it's height.
Answer:A
Step-by-step explanation:
-8=a(2+5)^2 + 41
-8=a x 7^2 + 41
-8=a x 7 x 7 +41
-8=49a+41
Collect like terms
-8-41=49a
-49=49a
Divide both sides by 49
-49/49=49a/49
-1=a
a=-1
Change 5/3 to 15/9. Then add 15 + 17 and put it over 9. 32/9
Answer:

Step-by-step explanation:
Equation of the line that passes through (-2, 8) with a slope of 0, can be written in point-slope form,
and also in slope-intercept form,
.
Using a point, (-2, 8) and the slope (m), 0, substitute x1 = -2, y1 = 8 and m = 0 in
.
Thus:


Rewrite in slope-intercept form
(addition property of equality)
