Determine the output, f(x), if the input to the function box below is 8. f(x)=3x-1

Harman [31]

Answer:

The output is 23

Step-by-step explanation:

we know that

f(x) ----> is the output

x ----> is the input

we have that

f(x)=3x-1

For x=8 (input)

Find the value of f(x) (output)

f(8)=3(8)-1=23

The output is 23

5) Find the area of a rectangle with points at (-8,5), (2,5), (2,-3) and (-8,-3).

Lady bird [3.3K]

Answer:

80 units²

Step-by-step explanation:

Given vertices of a rectangle:

A = (-8, 5)
B = (2, 5)
C = (2, -3)
D = (-8, -3)

As points A and D share the same x-coordinate, and points B and C share the same x-coordinate, the difference between the different x-coordinates is the length of the rectangle:

$\begin{aligned}\implies \textsf{Length} & = x_B-x_A\\& = 2-(-8)\\& = 2+8\\& = 10\; \sf units\end{aligned}$

As points A and B share the same y-coordinate, and points C and D share the same y-coordinate, the difference between the different y-coordinates is the width of the rectangle:

$\begin{aligned}\implies \textsf{Width} & = y_A-y_D\\& = 5-(-3)\\& = 5+3\\& = 8\; \sf units\end{aligned}$
