Answer:

a = 16

b = -6

Step-by-step explanation:

a + 2b = 4

2a + b = 26

2a + 4b = 8

2a + b = 26

3b = -18

b = -6

a + 2(-6) = 4

a - 12 = 4

a = 16

If f(g(x)) = g(f(x)) = x, and<br> g(x) = 2 + In(x + 1), find f(4).

Dmitriy789 [7]

If $f(g(x))=g(f(x))=x$ , then $g$ and $f$ are inverses of one another. So we know $g(f(4))=4$ .

$g(f(4))=2+\ln(f(4)+1)=4$

$\implies\ln(f(4)+1)=2$

$\implies f(4)+1=e^2$

$\implies\boxed{f(4)=e^2-1}$

Answer:

Step-by-step explanation:

KL = JK, so ΔJKL is an isocesles triangle, then m∠J = m∠L

KL is a tangent line, so ∠JKL = 90°,

so m∠J = 45°
