When you write that equation, you get 3x^2+6=81.

Solving for x:

Subtract by 6 on both sides of the equation to get 3x^2=75.

Then, divide by 3 on both sides of the equation to get x^2=25.

Finally, do the square root on both sides of the equation to get x=5.

The number is 5.

4. yes. when u distribute the -3, you get -3x-6 which is of course equal to -3x-6

Graph the line. y=-4x+6 what the graph
Aloiza [94]
So the -4x is the M and then 6 is the B. So m is the slope and B is the y-intercept. The 6 goes on the y axis and the -4 will be how the line looks. It’ll be rise (-4) over run (1).
