Answer:
4x +3y = 10
Step-by-step explanation:
The radius CD has slope Δy/Δx = (1-(-2))/(8-4) = 3/4.
The equation for the perpendicular line through point C(4, -2) can be written as ...
Δx(x -4) +Δy(y -(-2)) = 0
4(x -4) +3(y +2) = 0
4x +3y -10 = 0 . . . . . . general form equation for the line
4x +3y = 10 . . . . . . . . .standard form equation for the line
W = 120 + 5(h - 30).
So, if he works 35 hours, he will earn:
120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.
If he works 42 hours, he will earn:
120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.
Answer:
Step-by-step explanation:
32.12 meters below sea level. The diver ascended to the surface at a rate of 8.8 m/min. So the diver ascended 3.65 meters a minute.
a) Use d=rt. D=distance, t= minutes, r=rate
d=8.8t
b) The distance will never be a negative number because you can't have a negative distance to something.
c) 3.65 minutes for the diver to reach the surface.
Answer:
Kyle would save more using his 15% off of $1000 coupon.
Explanation:
15 ÷ 100 • 1000 = 150
1000 - 150 = $850
$150 is the amount the 15% coupon took off.
$850 is the amount Kyle will pay.
vs.
1000 - 80 = $920
