-12 + 20 = 8
then divide the answer by -4
8/(-4) = -2
when you divide a negative number, the answer will be the opposite sign of the numerator
-2 is your answer
hope this helps
3x +3 + x = -1
4x= -4
X= -1
Answer:
If the question is how much she earns per week the answer is $606.10
y = (x - 2)(x + 5) First I would multiply (x - 2) and (x + 5) together
y = x² + 5x - 2x - 10
y = x² + 3x - 10
Next I would plug in a number for x to find its y value. I will plug in 0
y = 0² + 3(0) - 10
y = -10
(0, -10) [this is the y-intercept (the y value when x = 0)]
Your answer is Graph A because the y-intercept is (0,-10)
The Mean Absolute Deviation is - 0 +0+0+1+3+8 = 24/ 6 which would = 4 that's the answer to your question .
Hope that it helps .
