What is the value of x? Show your work in arriving at your answer.
Trava [24]

Answer: x = 18

Step-by-step explanation:

First, since both angles shown are equal to each other, you can immediately set your equation.

5x + 5 = 95

Next, move 5 to the opposite side of the equation to isolate your x value (5x). This step is simply subtracting the hanging 5.

5x + 5 (-5) = 95 (-5)

5x = 90

Finally, you need to divide both sides of the equation by 5 (the 5 next to the x) to *fully* isolate the x value.

5x / 5 = 90 / 5

x = 18

final answer: x = 18

Hopefully this helps with the remainder of your lesson! :)

Two piecewise functions are shown below. What is the value of
gizmo_the_mogwai [7]

Step-by-step explanation:

I am not sure what your problem here is.

you understand the inequality signs ?

anyway, to get

6×f(-2) + 3×g(1)

we can calculate every part of the expression separately, and then combine all the results into one final result.

f(-2)

we look at the definition.

into what category is -2 falling ? the one with x<-2, or the one with x>=-2 ?

is -2 < -2 ? no.

is -2 >= -2 ? yes, because -2 = -2. therefore, it is also >= -2.

so, we have to use

1/3 x³

for x = -2 that is

1/3 × (-2)³ = 1/3 × -8 = -8/3

g(1)

again, we look at the definition.

into what category is 1 falling ? the one with x > 2 ? or the one with x <= 1 ?

is 1 > 2 ? no.

is 1 <= 1 ? yes, because 1=1. therefore it is also <= 1.

so we have to use

2×|x - 1| + 3

for x = 1 we get

2×0 + 3 = 3

6×f(-2) = 6 × -8/3 = 2× -8 = -16

3×g(1) = 3× 3 = 9

and so in total we get

6×f(-2) + 3×g(1) = -16 + 9 = -7
