Multiply the first equation by two to get 2x + 2y = 4. 
Subtract the second equation from the first equation to get -3y = -12

y = 4. 

Plug y back in to get x = -2.

Answer:

m∠2 is correct, m∠1 is 85°

Step-by-step explanation:

Since, you already gave the angle for ∠2 in which it is vertical to the one shown, m∠1 must be 85° since you are finding the left angle to make a straight line of 180°

Determine the slope of the line that is perpendicular to the line y = -7x - 12.
Mnenie [13.5K]

Answer:

None of these answers are correct.

Step-by-step explanation:

Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.

Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7

-x + 2y= -1 <br> x= -15<br> value of y?
kolbaska11 [484]
Simply plug in -15 for x in our given equation.

-x + 2y = -1

-(-15) + 2y = -1

Simplify.

15 + 2y = -1

Subtract 15 from both sides.

2y = -1 - 15

Simplify.

2y = -16

Divide both sides by 2

Y = -8

Hope I helped :)
