Simplify 12 to the 16th power over 12 to the 4th power.
12^12
12^4
1^12
1^4

Answers

Answer 1
Answer:  When dividing powers with the same base, just subtract the exponents with the same base as a single power. Formula = a^m / a^n = a^m^-^n 

12^1^6/12^4 

= 12^1^6^-^4 

=\ \textgreater \ 12^1^2 

= 8916100448256
Answer 2
Answer: 12^16/12^4=12^12 answer 12 to the 12th power all you do is substract the powers 16-4=12

Which is equivalent to 3x/x+5 - x-5/x

Answers

Answer:

B. (2x^2+25)/(x(x+5))

Step-by-step explanation:

x((3x)/(x+5))-(x+5)((x-5)/(x))

= (3x^2)/(x(x+5)) - ((x-5)(x+5))/(x(x+5)) = (3x^2-(x-5)(x+5))/(x(x+5))

= (3x^2-(x^2-25))/(x(x+5))

= (2x^2+25)/(x(x+5))

15 points-What is the equation in slope-intercept form of the linear function represented by the table?

Answers

slope-intercept form:
y=mx+b
m=slope
b=y-intercept.

1) We need to know the value of the slope (m):
Given two points (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)

We choose two points of this line:
(-1,-8)
(4,2)
The slope will be:  m=(2+8)/(4+1)=10/5=2

2) we have to find the y-intercept (b) of this line:
we choose any point of this line: for example (4,2) and plug in this point in this equation:
y=mx+b
therefore:
2=2(4)+b
2=8+b
b=2-8
b=-6

3) we can already make up the equation:
Data:
m=2
b=-6
y=mx+b
y=2x-6

Answer: y=2x-6

Which choice is the appropriate simplified form and restriction for the variable 2x-3x^2/5x^3a. 1/5

b. 1/5x, (x=0)

c 1/5x^2, (x=0)

d. 2-3x/5x^2, (x=0)

by the way all of the zeros have an slash through them which I couldn't figure out how to type. Could someone please please please help me?

Answers

If you would like to find the simplified form, you can do this using the following steps:

(2x - 3x^2) / (5x^3) = (x(2 - 3x)) / (x(5x^2)) = (2 - 3x) / (5x^2) if x != 0

The correct result would be (2 - 3x) / (5x^2) if x != 0.
