faltersainse [42]3 years ago
3 0

Answer:

x = 0 x = 1/9

Step-by-step explanation:

square both sides

x = 9x²

subtract x from both sides

9x² - x = 0

factor out x

x (9x-1) = 0

x = 0,

9x-1 = 0, 9x = 1

x = 1/9

Write the equation of the line that has a slope of m=3 and passes through (4 , 2)
mina [271]

Answer:

y=3x-10

Step-by-step explanation:

For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.

(y-y1)=m(x-x1)

(y-2)=3(x-4)

y-2=3x-12

y=3x-10

To check, you can plug the coordinates into the equation.

y=3x-10

(2)=3(4)-10

2=12-10

2=2
