Answer:
y = 2/7x + 7
Step-by-step explanation:
We start off by putting the original equation into slope-intercept form. Subtract 7x from both sides, then divide both sides by -2. Your new equation should be y = -7/2x - 8. It's important to know that when two lines are perpendicular, their slopes (m) are opposite reciprocals of each other. So -7/2 becomes 2/7. The first part of your final equation is y = 2/7x + b.
Next, we need to find the y intercept (b). You need to plug the x and y values from the given coordinate point (-7,5) into your final equation. You should end up with: 5 = 2/7(-7) + b. Then, solve for b.
5 = -14/7 + b
5 = -2 + b
7 = b
Finally, plug the b value into your final equation and you will have your answer.
2 x 50 = 100

Answer:
x=35
y=34
Step-by-step explanation:
x+y=-1
x+3y=67
x=-3y+67
-3y+67+y=-1
-2y+67=-1
-2y=-68
y=34
x=-35
Answer:
3 places to the right
Step-by-step explanation:
6.8 x 100 is 680 so if you move the decimal three places to the right, you get 680!
Add 1/4 by 1/6 and get 5/12 so then you have 7/12 with black hair.
