Associative Property of Multiplication

Solve for x

100

Solve for x:

2x-2²=16

x=10

200

Solve for x:

4(x+2)²=(2x+3)²

x=7/4

300

Solve for x:

(1/2)x + (4x+1)/7 = (3/14) + (1/7) x

x=1/17

400

Solve for x:

3y+4x+7=5(x-7y)

x=38y+7

500

Solve for x:

4(x+7)-5x=12(x+1)+16

x=0

Lines

100

If my line has a zero slope, my equation is in the form of ______

y=____

200

WTEOTL given the slope is -3 and the y intercept is -17

y= -3x - 17

300

WTEOTL given the line passes through these two points: (-5, 8) ( -5, 90)

x= -5

400

WTEOTL that is parallel to 2y-3x = 80 and passes through (0, -29)

y= (3/2)x - 29

500

WTEOTL that has the same y-intercept as y=-17 and is parallel to 7x + (3/4)y=98

y= (-28/3)x -17
