Answer:

3x-6

Step-by-step explanation:

(f+g)(x) would be the same as saying 2x+1+x-7, so then you would just simplify by combining like terms.

Dirk opened up a savings account with $600. At a yearly interest rate of 5 percent that is compounded monthly, how much interest
gladu [14]

Answer:

Hence final answer is $15.17

Step-by-step explanation:

Given that Dirk opened up a savings account with $600.

So P=$600

"At a yearly interest rate of 5 percent"

Means r=5% = 0.05

"compounded monthly" means n=12

i= monthly rate of interest = r/n=0.05/12

"how much interest will Dirk earn in six months." means find Interest when time is 6 months


Plug these values into compound interest formula:

A=P\left(1+i\right)^t

A=600\left(1+\frac{0.05}{12}\right)^6

A=600\left(1+0.00417\right)^6

A=600\left(1.00417\right)^6

A=600\left(1.02528228828\right)

A=615.169372966

which is approx

A=615.17

Now interest earned will be difference of A and P

Interest =A-P=615.17-600=$15.17

Hence final answer is $15.17

Describing Types of Dilations
Sergio039 [100]

Answer:

The key fact about the enlargement, scale factor > 1

The key fact about the reduction, 0 < scale factor < 1

Step-by-step explanation:

<em>Let us explain what is the dilation?</em>

  • A dilation is a transformation that changes the size of a figure.
  • It can become larger or smaller, but the shape of the  figure does not change.
  • The scale factor measures how much larger or smaller  the image will be
  • If the scale factor greater than 1, then the image will be larger
  • If the scale factor between 0 and 1, then the image will be smaller

Enlargement means the image of a figure after dilation is larger than the original figure

Reduction means the image of a figure after dilation is smaller than the original figure

The key fact about the enlargement is that the scale factor of dilation must be greater than 1 ⇒ scale factor > 1

The key fact about the reduction is that the scale factor of dilation must be between 0 and 1 ⇒ 0 < scale factor < 1
