Answer:
B
the equation:
3x-7=9+2x
step 1: subtract 2x from both sides
x-7=9
step 2: add 7 to both sides
x=16
<h2>answer:</h2>
13/8
alternative forms:
1 5/8, 1.625
<h2>step-by-step explanation: </h2>
2 1/8-1/2
multiply 2 and 8
16+1/8-1/2
add 16 to 1
17/8-1/2
least common multiple of 8 and 2 is 8. Convert 17/8=2.125 and 1/2=0.5 to fractions with denominator 8.
17/8-4/8
subtract numerators and put denominators as only one 8.

e.
5^0 = 1; 5^1 = 5; 5^2 = 25; 5^(-1) = 1/5; 5^(-2) = 1/25
This is an exponential function since the exponent is a variable.
Function: f(x) = 5^x
Recursive: 
f.
Look at f(x) = x^2 for x = -2, -1, 0, 1, 2
f(-2) = 4
f(-1) = 1
f(0) = 0
f(1) = 1
f(2) = 2
Now look at the y-values in the table. They are the same we have here added to 5.
Your function is a quadratic function.
f(x) = x^2 + 5
Answer
23.70
Proof
3Q+5+2-8-5=65 ~ Simplify
3Q-6=65 ~Cancel out the six
+6 +6 ~Add 6 to both sides since it is a 3Q=71 negative.
/3 /3 ~Cancel out the three.
Answer ~Divide both sides by 3
Q=23.66
Rounded Up
Q=23.70
