Answer:
Slope: 1
Step-by-step explanation:
A variable is always worth 1 if there is no number in front of it. In this case there is no number, so just draw in a one.
Answer:

Your teacher messed up the question so just put the top right answer and ask your teacher if they did accidently miss-type.
Step-by-step explanation:
The first thing to do in this equation is look at the exponents. When multiplying a variable (or any number equal to itself with the same exponent) you only have to add the exponent. So for a, you would add the exponents to get 0, so a to the power of 0 is 1, because any number to the power of 0 is 1. For b, we would add the 3 and 1. (When no exponenet is present in a number then it is 1, so for this I added 3 and 1). So it would be 4. The correct answer is

Answer:
x ≤ 1
Step-by-step explanation:
Swapping sides of the inequality requires reversing its sense.
If 1 is greater than x, then x is less than 1.
Answer:
F(x) and h(x)
Step-by-step explanation:
f(x) has a high of three and so does H(x), g(x) has a high of -2 so it doesn't count
