Answer:
17
Step-by-step explanation:
9 years ago, she was 8 years old. So, you'd take her age then + number of years passed. So, 8+9=17.

Answer:
Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.
Step-by-step explanation:
It is given that V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail.
We need to find the meaning of V(2)=T.
On comparing V(d) and V(2), we get d=2.
Since V(d) models Erica's vertical distance from the top of the valley (in kilometers) after walking d kilometers along the trail, therefore V(2) models Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail.

It means Erica's vertical distance from the top of the valley (in kilometers) after walking 2 kilometers along the trail is T.
vertex = (10, - 8)
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 10)² - 8 is in this form with (h, k) = (10, - 8) ← vertex
Answer:
33x - 13 = 13x + 7
Step-by-step explanation:
If "G" is the midpoint of line FH, then both segments (lines FG and GH) must be the same length. Therefore, to find "x", you can set both segments equal to each other. After doing this, you can simplify and isolate to find "x".
FG = 33x - 13
GH = 13x + 7
FG = GH
33x - 13 = 13x + 7
