Simplify the expression by combining like terms. 1/2d−3/4d+3f−2f

Answers

Answer 1
Answer:

Answer:

-1/4d+f

Step-by-step explanation:

First find a common denominator for the like terms 1/2d and -3/4d by multiplying 1/2d by 2/2 to get 2/4d.

Now you have common denominators so 2/4d-3/4d=-1/4d.

For the numbers that have a variable of f, 3f-2f=f.

Therefore the answer is -1/4d+f

Hope this helped!

Original price: $32 ;Markup: 12.5% ; What is the retail price

Answers

If you would like to know what is the retail price, you can calculate this using the following steps:

original price ... $32
markup ... 12.5%

12.5% of $32 = 12.5% * 32 = 12.5/100 * 32 = $4
$32 + $4 = $36

Result: The retail price is $36.
It think 36$ but I am not 100 percent sure, I learned how to do this but  I was taught to find the percentage up the markup.

Graph the data from the table below. Describe the parent function as linear, square root, cube root, cubic, or quadratic.

Answers

The function rule is g(x) = 2*sqrt(x) which is a transformation of the parent function f(x) = sqrt(x)

The g(x) function has been scaled by a factor of 2. In other words, each point on g(x) is twice as high as its corresponding point on f(x). Specifically for example, the point (1,1) has been doubled to (1,2). Overall, this vertically stretches out the parent function graph.

Both the parent function f(x) and the other g(x) curve are square root functions. 

See the attached image. The blue curve goes through the given points from the table. The red curve is the parent function.
