Whats the value of x?
Nutka1998 [239]

Answer:

x = 8 units, measure of angle AFE = 60 degrees, measure of angle CFD = 60 degrees

Step-by-step explanation:

Finding x:

You know all three of the given measures add up to 180 because they are on the same side of the line. Write an equation and solve for x.

6x + 2 + 8x + 6 + 7x + 4 = 180

21x = 168 --> x = 8

Angle AFE:

Substitute the value of x in the given measure.

7x + 4 = 7*8 + 4 = 56 + 4 = 60

Measure of angle CFD:

Angle AFE is it's vertical angle, so their measures (60 degrees) are equal.

If f(x) =3x-5 them find values of f(3) and f(-7). please explain step by step​
LenKa [72]

Answer:

f(3) = 4

f(-7) = -26

Step-by-step explanation:

Hi there!

f(x) =3x-5

To find f(3), replace every x with 3:

f(3) =3(3)-5\\f(3) =9-5\\f(3) =4

Therefore, f(3)=4.

f(x) =3x-5

To find f(-7), replace every x with -7:

f(-7) =3(-7)-5\\f(-7) =-21-5\\f(-7) =-26

Therefore, f(-7)=-26.

I hope this helps!
