Answer:
3 0 -7 4
Step-by-step explanation:
you figure this out by looking at where you know the x or y value is and you find the line at that coordinate and then you look at where the other value is (x or y)
Answer:
48390,"37,520","65,810",2170 or 2180 (both will work)
Answer:
Step-by-step explanation:
absolute(5x + 6) = x
There are 2 solutions to this
Solution 1
5x + 6 = x Subtract 5x from both sides.
5x - 5x + 6 = x - 5x
6 = - 4x Divide by - 4
6/ - 4 = -4x / -4
x = - 1.5
Solution 2
5x + 6 = - x
6 = -x - 5x
6 = - 6x
x = 6/-6
x = - 1
Here is a graph which shows the solutions.
So the original price is "x".
the discounted price by 10% is P(x) = 0.9x.
the price minus a $150 coupon is C(x) = x - 150.
so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.
C( P(x) ) = P(x) - 150
C( P(x) ) = 0.9x - 150
