The formula to find the slope of a line is
.
I'm not sure if my fraction looks right, so I'll add it in a separate attachment too.
The hourly rate of $7.59 per hour multiplied by hours gives the gross wages earned. If 10% are taken for taxes then 90% are take home wages.
(0.9)*(8 hr/day) * (7.59 $/hr ) = 54.65 $/day take home pay
The answer of 2.5% of 28 is 0.7
So it can now be bought for 65% of its regular price.
That's a good deal. If I needed a clearance rack, I'd buy it.
Answer:
steps below
Step-by-step explanation:
a) f(x) = (x+2)² - 9
b) y = (x-h)² + k , (h,k) is vertex vertex (-2 , -9)
x intercept: (x+2)² - 9 = 0
x+2 = ± 3
<u>x = 1 or x = -5</u>
y intercept: <u>y = -5</u>
c) attached
d) y ≥ -9 [-9,∞)
