Answer:
Evaluate the function : F (x) = 17x - 51
exact value: F= -17 - 51/x
solve for x : x= - 51/F+17
graph: F (x) = 9* -3 +10 * -2 - 17x - 2
find the roots: x = -3
Step-by-step explanation:
Find slope
slope betwen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
first make denoms same
denom is 10
(4/5,1/5) turns to (8/10,2/10)
(1/2,3/2) turns to (5/10,15/10)
slope=(15/10-2/10)/(5/10-8/10)=(13/10)/(-3/10)=13/-3=-13/3
use point slope
use (4/5,1/5)
y-y1=m(x-x1)
a point is (x1,y1) and slope is m
y-1/5=-13/3(x-4/5)
expand
wait, we don't need to do that, the only one with slope -13/3 is D
answer is D
Subtract the sides of the equation plus 5
Subtract the sides of the equation minus x
Divided the sides of the equation by 3
So the measure of the angle equals :

The equation that could be used to find x, the average number of feet the tree grew each month is; 14x + 10 = 56.2
<h3>Algebra Word Problems</h3>
We are told that the tree was planted at a height of 10 ft.
Period for which tree was planted = 14 months
Height of tree after 14 months = 56.2 ft.
Thus, if x is the average number of feet the tree grew each month, then the equation to find x is;
14x + 10 = 56.2
