The value of r(x) at f(- 6) = 8.
We have the function r(x) =
We have to find the value of r(x) at x = - 6.
<h3>If f(x) = 5x + 3, then find the value of f(-2).</h3>
Substitute x = - 2 in the value of f(x) -
f(-2) = 5 (-2) + 3 = - 10 + 3 = - 7.
According to question, we have -
f(x) =
Substitute r = -6 in f(x), we have -
f(-6) =
f(-6) = - 2 x - 2 + 4
f(-6) = 4 + 4 = 8
Hence, the value of f(x) at f(- 6) = 8.

Answer:
Step-by-step explanation:
The triangles CED and CGF are similar since two sides are on same line and one side is parallel.
<u>Corresponding sides have equal ratios:</u>
- CG/CE = CF/CD
- CG/CE = (CD - 1.8)/CD
- 6/(6 + 2.4) = (CD - 1.8)/CD
- 6/8.4 = (CD - 1.8)/CD
- 1/1.4 = (CD - 1.8)/CD
- 1*CD = 1.4CD - 1.4*1.8
- 0.4CD = 2.52
- CD = 2.52/0.4
- CD = 6.3
Like what is it’s meaning in that problem.
