For # 1, the answer will be 1 because of the exponential rule

.
#2, the answer is going to be

because of the exponential rule

.
#3. I'm not sure that this could be simplified any further.
#4 To get the answer to this question, we must apply the distributive property, along with the exponential rule
. When we apply these properties, we'll get

For the other questions, they all apply the Laws of Exponents.
Answer: 36 days
Step-by-step explanation:
that’s the lowest multiple of 9 that also is a multiple of 12. It’s the LCF aka Least Common Factor
Hmm, seems to multiply by 5
wait, no
first is multiply by 5
2nd is multiply by 10
3rd is multiply by 15
4th is multiply by 20
seems to be

or

the rule is square the input then multiply by 5
Answer: Y = 1/4x - 2
Slope intercept form is y = mx + b
M is slope, and b is y intercept
Solving slope:
change in y over change in x is slope
The change in y from (0,-2) and (4,-1) is up one over four.
This can be represented as 1/4
Solving y-intercept:
Y-intercept is when x = 0 or when the line touches the y axis
As you can see on the graph, the y intercept is (0,-2) or -2
Final:
Y = 1/4x - 2
