18/5 is basically 3 3/5 as a mixed number. When you convert a fraction to a decimal, you always want the denominator to either 10, 100, or 1000 so that the number is accurate. And so you multiply the denominator by what ever number will get 10, 100 or 1000, in which in this case is 10 when you multiply by 2. Multiply the numerator(3) by 2 so that it will be the same value. You should now have 3 6/10. After that, since 6/10 is basically 60/100, take out the 100 and move the decimal unit 2 units to the left of 60. And since you still have the whole number three, your final answer will be 3.6.

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -1/2f(x)?
Natasha2012 [34]

Answer:

For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression

Step-by-step explanation:

Parent function is f(x)= x

We need to find the effect of the graph when f(x) is replaced with -1/2f(x)

When negative sign is multiplied outside f(x) like -f(x),  then there will be a reflection over x-axis

When negative sign is multiplied inside f(x) like f(-x) then there will be a reflection over y-axis

When a number is multiplied outside f(x) then there will be a vertical stretch or compression

Here 1/2 is multiplied outside f(x). \frac{1}{2} is less than 1 so there will be a vertical compression

For negative sign , the graph reflects over x -axis and for 1/2 there will be a vertical compression

Factor the greatest common factor out of 8x^3 + 28x^2 + 40x
Liula [17]

Answer: 4x(2x^2+7x+10)

Step-by-step explanation:

The Greatest Common Factor (GCF) of a polynomial is defined  as the largest monomial that is a factor of all the terms of the polynomial.

In this case, given this polynomial:

8x^3 + 28x^2 + 40x

You can factor out the Greatest Common Factor applying this procedure:

1. Write the terms of the polynomial in prime factor form:

8x^3=2*2*2*x*x*x\\\\28x^2=2*2*7*x*x\\\\40x=2*2*2*5*x

2. Identify the factors the terms have in common (this will be the Greatest Common Factor). In this case this is:

GCF=2*2*x=4x

3. Finally,  rewrite the expression in factor form:

4x(2x^2+7x+10)
