Answer:
60%
Step-by-step explanation:
89+96+97+s = 360..... therefore when you add all 89+96+97(282) and subtract it from 360 you get 78. so s = 78.
If 2x+y=5, then y=5-2x, so he substituted 5-2x correctly.
x+4x=5x, so he combined like terms correctly.
If 5x-10=10, then 5x=10+10 -> 5x=20, so he subtracted 10 from the right side instead of adding 10 to the right side.
The answer is C.
Here's the correct solution:
The midline of the standard cos function is y=0
the function is translated 5 units up.
so the answer is e: y=5.
-16 divided by 4 equals -4
