2x + y = 7 is an eqn of a straight liney = -2x +7with a slope of -2, and an intercept of 7 the table is for a straight line with a positive slope of 2found from e.g using the first two points in the table: (1 - -1)/(-3 - -4) = 2and an intercept of 7y = 2x + 7 or-2x + y = 7

If m<1=6x+50 and m<2=4x+40 find x

dolphi86 [110]

Angle 1 and 2 are supplementary angles and need to equal 180 degrees

so angle 1 + angle 2 = 180:

6x+50 + 4x+40 = 180

combine like terms:

10x + 90 = 180

subtract 90 from each side:

10x = 90

divide both sides by 10

x = 9

4 = -7s - 10<br><br> how do you get -2? please show your work

andreyandreev [35.5K]

First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
