Answer:
-25 ≠ 21
Step-by-step explanation:
it looks like the question is asking you to solve 5x=4y+9 when given the ordered pair (-5,3)
you would substitute -5 for x and 3 for y in the equation
5(-5) = 4(3) + 9
-25 = 12 + 9
-25 = 21
the question is asking you to see if the left side is equal to the right side of the equation
-25 is not equal to 21, therefore (-5,3) is not a solution to the equation
Answer:
r=-40
Step-by-step explanation:
r/-8=5
times -8 on both sides
5 times -8 =-40
r=-40
168
You add 4, 1, and 2 to get 7. You put 4/7=x/294. Then you use proportions to solve for x.
7x=1176
x=168
Hey mate !!
Here's your answer !!
2w^2 - 11w = -12
2w^2 -11w + 12 = 0
2w^2 - 8w - 3w + 12 = 0
2w ( w - 4) -3 ( w - 4) = 0
(2w - 3) ( w - 4) = 0
Hence
2w - 3 = 0
2w = 3
w = 3/2
w - 4 = 0
w = 4
Hence value of w are 4 and 3/2
Hope this helps!!
Cheers!!
