Answer:
If two powers have the same base then we can multiply the powers. When we multiply two powers we add their exponents.

Answer:
y = -3/2x + 6
Step-by-step explanation:
Parallel lines have the same slope so slope is -3/2
Using (4,0)
y = mx + b
0 = -3/2(4) + b
0 = -6 + b
b = 6
so y = -3/2x + 6

Answer:
   (b) 15.32
Step-by-step explanation:
You can use your triangle sense to answer this.
The side x will always be shorter than the hypotenuse, 20. This eliminates the last two choices.
If the angle is 45°, then the sides are equal at about 0.707 times the length of the hypotenuse. That would make them 0.707×20 = 14.14. Since the angle is greater than 45°, the opposite side will be greater than 14.14. Only one answer choice fits between 14 and 20: the second choice -- 15.32.

The mnemonic SOH CAH TOA reminds you of the relation ...
   Sin = Opposite/Hypotenuse
   sin(50°) = x/20
   x = 20×sin(50°) . . . . multiply by 20 to find x
   x ≈ 15.32 . . . . . . . . . use your calculator to evaluate
