7 0

Answer:

3(x+8)=4+x

distribute the 3 by multiplying it with the x and the 8

3x+24=4+x

subtract x from both sides

2x+24=4

subtract 24 from both sides

2x=4-24

2x=-20

divide each side by 2

leaving the variable isolated

x=-10

Step-by-step explanation:

It is important to balance each side by doing the same to both sides such as at the end divide both sides by 2.

stepladder [879]

Answer:

-15

Step-by-step explanation:

Given:

  • x=-7
  • -14+7=x+8

Simply plug in and see if the statement is true. If not, isolate x.

Test for truth:

  • -14+7=-7+8
  • -7=1
  • NOT true.

Isolate x in original equation:

  • -14+7=x+8
  • -14+7-8=x
  • -7-8=x

A circle has its center at (1,4) and a radius of 2 units what is the equation of the circle
joja [24]

Answer: x² + y² - 2x - 8y + 13 = 0

Step-by-step explanation:

the equation of the circle is in the form (x - a)² + (y - b)² = r²

where (a,b) is the center of the circle and r is the radius

      hence the equation is

                         (x - 1)² + (y - 4)² = 2²

                         x²-2x+1+y²-8y+16= 4

                         x²+ y² -2x- 8y + 17 =4

                         x² + y² - 2x - 8y = -13

                          x² + y² - 2x - 8y + 13 = 0
