Answer: x = 27

Explanation:

3x - 4y = 65
3x - 4(4) = 65
3x - 16 = 65
3x = 65 + 16
3x = 81
x = 81/3
x = 27

Hello there! :)

Answer:

\huge\boxed{x = 27}

Given the equation:

3x - 4y = 65 where y = 4

Substitute in 4 for "y":

3x - 4(4) = 65

Simplify:

3x - 16 = 65

Add 16 to both sides:

3x - 16 + 16 = 65 + 16

3x = 81

Divide both sides by 3:

3x/3 = 81/3

x = 27.

Which line segment is a radius of circle F? A: AC B:ED C:FE D:DC (Circle with center at point F. Points A, B, C, D, and E are on
weqwewe [10]

Answer:

The correct option is C.

Step-by-step explanation:

It is given that the point F is the center of the circle and the points A, B, C, D, and E are on the circle.

A line segment joining any point on the circumference to the center of the circle is known as radius of the circle.

Since F is the center of the circle and the points A, B, C, D, and E are on the circle, therefore the line segments FA, FB, FC, FD and FE radius of the circle F.

So, option C is correct.

| x - 8| = 3

x - 8 = 3            - (x - 8) = 3
x = 3 + 8           -x + 8 = 3
x = 11                -x = 3 - 8
                         -x = - 5
                           x = 5

A. Draw the graph of the function y = |x - 2| - 1. B. Label the vertex and all intercepts. Upload a copy of your handwritten gra
hjlf

Step-by-step explanation:

y = |x - 2| - 1

Given equation is in the form of y=|x-h|+k

Where (h,k) is the vertex

h = 2  and k =-1

So (2, -1) is the vertex for the given function

To find x intercepts we plug in 0 for y

we will get two values for x because of absolute function

0 = |x-2| -1

add 1 on both sides

|x-2| =1

x-2 =1                          and x-2 =-1

x= 3                          and x= 1

So x intercepts are (1,0)  and (3,0)

the graph is attached below
