Let f(x) = 2x–8 and g(x) = x + 2. Find f(g(x)) and g(f(x)).

Anna71 [15]

Answer:

g(f(x)) = 2x - 6

f(g(x)) = 2x - 4

Step-by-step explanation:

g(f(x)) = 2x - 8 + 2

g(f(x)) = 2x - 6

f(g(x)) = 2(x + 2) - 8

f(g(x)) = 2x - 4

Evaluate the function f\left(x\right)=5x+2\mid11-5x\mid-4f(x)=5x+2∣11−5x∣−4 for x = -5.

Anestetic [448]

Answer:

$f\left(5\right) = 43$

Step-by-step explanation:

Given

$f\left(x\right)=5x+2\mid11-5x\mid-4$

Required

Solve for x = -5

This implies that we substitute -5 for x in $f\left(x\right)=5x+2\mid11-5x\mid-4$

$f\left(5\right)=5(-5)+2\mid11-5(-5)\mid-4$

Open all brackets

$f\left(5\right) = -25+2\mid11+25\mid-4$

$f\left(5\right) = -25+2\mid36\mid-4$

Absolute value of 36 is 36; Wo, we have:

$f\left(5\right) = -25+2*36-4$

$f\left(5\right) = -25+72-4$

$f\left(5\right) = 43$

What is the value of x? 45° 2 (2x - 5) > n

Vladimir [108]

Answer:

70 degrees

Step-by-step explanation:

Find the diagram attached

The sum of the angles is supplementary that is

45 + 2x- 5 = 180

2x + 40 = 180

2x = 180 - 40

2x = 140

x = 140/2

x = 70

Hence the value of x is 70 degrees
