The rule for dividing exponents is:For exponents with the same base, you can subtract the exponents and put the difference as exponent over the base. Remember that the fraction bar acts as a division sign! Or:

Answer: 
I'm going to set up an equation to find the amount of momey Elisa has, then we can check our answer
e + 2e + 2e + 5 + 2e + 5 · 3 + e + 2e = 69
Simplify:
10e + 30 = 69
Subtract 35 from each side:
10e = 39
Divide by 10 on each side
e = 3.9
We can check our answer by putting the value in the simplified equation.
10 · 3.9 + 30 = 69
Yep! The equation is correct. Now for the answer.
Elisa
3.9
Jacob
7.8
Sandra
12.8
Damian
38.4
Martin
11.7

The simplified form of the expression [1/5 (-16-9) + 4² ÷ 8] is -3.
Option A) is the correct answer.
<h3>What is the simplified form of the expression?</h3>
Given the expression; 1/5 (-16-9) + 4² ÷ 8
First we remove the parentheses and perform the operations using the guidelines of BODMAS
1/5 (-16-9) + 4² ÷ 8
1/5 × -25 + 4² ÷ 8
1/5 × -25 + 16 ÷ 8
-25/5 + 16/8
-5 + 2
-3
The simplified form of the expression [1/5 (-16-9) + 4² ÷ 8] is -3.
Option A) is the correct answer.

The first graph is a function but the second is not because it doesn’t pass the vertical line test
So x+x^2=20
subtract 20 from both sdies
x^2+x-20=0
factor
find what 2 nmbers multiply to get -20 and add to get 1
factors of 20=2 times 2 times 5
the combos are
2 times 10
4 times 5
1 times 20
4 and 5 are 1 in diference
5-4=1
5 times 4=20
(x-4)(x+5)=0
if xy=0 then x and/or y=0
set each to zero
x-4=0
add 4
x=4
x+5=0
subtract 5
x=-5
but you want positive so this is an extranius answer so discard this
the number is 4
