Answer:
Step-by-step explanation:
ok so do this
9x² + 3x - 8 - (3x² + 8x)
distribute the negative sign
9x² + 3x - 8 - 3x² - 8x
simplify
6x² - 5x - 8
hope this helps <3
Answer:
angle 1: 80 degrees
angle 2: 112 degrees
angle 3: 131 degrees
angle 4: 80 degrees
angle 5: 37 degrees
Step-by-step explanation:
start out with angle three subtract 49 from 180 ( a straight line must be 180 degrees) and u get 131. then add 63 and 49 up and subtract from 180. you get 68. angle 2 would be 180 - 68 and you get 112. once you know angle 2, you add up 31 and angle two (112 degrees) and subtract from 180, which leaves you with 37 degrees (angle 5). Add up angle 5 (37 degrees) and 63 degrees and subtract from 180, you get 80 degrees (angle 4). and opposite nagles equal each other so angle one is also 80 degrees.
Answer: I hope you understand, just mutiply whatever x is by 11 to get Y
Step-by-step explanation:
x = unknown number
9x+2x= 11x
Y=11x
Change the equation 3x + 2y = -16 into: -3x -2y = 16
2x - 5y = 2
+ -3x - 2y = 16
-x - 7y = 18
-x = 18 + 7y
x = -7y - 18
Plug "x" into either one of the equations
3(-7y-18) + 2y = -16
-21y - 54 + 2y = -16
-19y - 54 = -16
-19y = 38
y = -2
Since we have the actual value of y, we can plug that into either one of the equations to find the value of x.
3x + 2(-2) = -16
3x - 4 = -16
3x = -12
x = -4
So.. The answer for the problem is D (-4, -2).
