What is the scale factor.

Lana71 [14]

Answer: A factor is a number that divides into another number exactly and without leaving a remainder.

Most numbers have an even number of factors; however, a square number has an odd number of factors.

How do I simplify the following expression.

elena55 [62]

How I Was Taught You Do Foil F-First O-Outer I-Inner L-Last So You Would Multiply First Number With The Other First Number Which Is The 4b×4b=16b² Then You Solve The Outer 4b+1 Then The Inner -1+4b & The Last -1+1

Darren bought some paint. He used 2 1/4 gallons painting his living room. After that, he had 3 5/6 gallons left. How much paint

Otrada [13]

Answer: $6\frac{1}{12}\ gallons$

Step-by-step explanation:

We can make the conversion from mixed numbers to improper fractions:

Multiply the whole number part by the denominator of the fraction.
Add the numerator of the fraction and the product obtained (This sum will be the new numerator).
The denominator is the same.

Then:

$2\frac{1}{4}=\frac{(2*4)+1}{4}=\frac{9}{4}\\\\3\frac{5}{6}=\frac{(6*3)+5}{6}=\frac{23}{6}$

We need to add the fractions in order to calculate the amount of paint Darren bought. Since the denominators are differente, we must find the Least Common Denominator (LCD):

$4=2*2=2^2\\\\6=2*3\\\\\\LCD=2^2*3=12$

Then:

$\frac{9}{4}+\frac{23}{6}=\frac{27+46}{12}=\frac{73}{12}\ gallons$

To convert this improper fraction to a mixed number:

When you divide 73 by 12 you get a quotient of 6. This will be the whole number.
The remainder obtained is 1. This will be the numerator of the fraction.
The denominator does not change.

Then:

$\frac{73}{12}\ gallons=6\frac{1}{12}\ gallons$

Which of the following relation is correct

o-na [289]

Answer:

Both the equation and its inverse are functions.

Step-by-step explanation:

In order to solve this problem lets first find the inverse of this function. This is done below:

$y = x^2 + 8\\$

We first swap x and y.

$x = y^2 + 8$

We now isolate y.

$y^2 = x - 8\\y = \sqrt{x - 8}\\f^{-1}(x) = \sqrt{x - 8}$

Functions are relations between two groups of numbers, in such a way that one number on the input group must generate a singular answer from the output group. This holds true for both f(x) and its inverse, therefore both are functions.
