Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:
As you can see, when you can add the exponents when you have powers with equal base.
Then, 
and 
do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
Answer: first one (-4,1) and the second is (0,1)
Step-by-step explanation:
Answer:
y = -x
Step-by-step explanation:
slope = change in y/change in x
slope = -1
Find the y-intercept
x value difference between (0,0) and (1,-1) = 1
if change in x = 1 then change in y = -1 so y-intercept = -1 + 1 = 0
y = -x + 0
Answer:f(2x+2)=4x2+2x−2
Step-by-step explanation:
Answer:
2/5 = 6/15
1/3 = 5/15
Step-by-step explanation:
LCD of 5 and 3 is 15.
So 2/5 = 2*3/15 = 6/15
and
1/3 = 5*1 / 15 = 5/15
