B) The hiker starts at -10 feet then increases altitude by 10 feet.
C) The hiker starts at 10 feet then increases altitude by 10 feet.
D) The hiker starts at -10 feet then decreases altitude by 10 feet

answer: a

step-by-step explanation:

10.2 units

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

step-by-step explanation:

tangent z: 4/3

cosine y: 4/5

cotangent y: 4/3

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
