The answer is -6 because the square root of 36 is 6, but then you have to add the negative in front of it.
First <u>rewrite the equation</u> in slope intercept form
slope intercept form: y = mx + b [ where m is slope and b is y-intercept ]
<u>comparing</u> with y = mx + b
- slope: -1/4 and y-intercept: 4
x-intercept: ( then y will be 0 )
In order to graph the line
- plot x = 16 on the x-axis coordinate: (16, 0)
- plot y = 4 on the y-axis coordinate: (0, 4)
- Then using a scale/ruler draw a straight line through this points.
Graph:
2(10v - 5) + 5v + 5v =
= 20v - 10 + 5v + 5v =
= 20v + 5v + 5v - 10 = <u>3</u><u>0</u><u>v</u><u> </u><u>-</u><u> </u><u>1</u><u>0</u> ← the end
Answer:
He did not multiply x by 2 when he used the distributive property at the beginning of the problem
