B. is the correct answer. If you think about it in slope-intercept form y = mx + b, remember that m is the slope so it would have to be -2. In this case, B is y = -2x + 1 so -2 is the slope :) Hope this helps!
You have to solve it first.
2x+4y=-8
-2 =-2
-10
4y=-10

4y
4 divided by -10 is -4
Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
Answer:
No solution.
Step-by-step explanation:
Subtract x from both sides:
Since both sides are not equal, there is no solution.
Answer:If the total perimeter of a pentagon with 5 sides is 40 centimeters, then each side would be 8cm
