The answer to the expression is 10.

Substitute the values of x and y into the expression.

x-y+8

5-3+8

Subtract/add from left to right.

2+8

First, you input the numbers that have the variables. So the first equation would be 5-3+8. That equation equals 10.

A computer sells for $430 which is 75% reduction of the original price. What is the original price of the computer?

garri49 [273]

Divide 430 by 75 to get 1% of the price.
430 / 75 = 5.733333...
Multiply that answer by 100 to get the original price.
5.73333... x 100 = 573.3333...
That will be your answer.

To double check your work, you can multiply 573.333... by 75 to see if the number in the problem (which was 75% of the original price) matches.
573.3333... x 75 = 430.

Hope that helped! :)

How many values of x solve the equation g(x)=2? How can you illustrate your answer on the graph? Remember, we are not looking fo

kumpel [21]

Answer:

3 solutions

Step-by-step explanation:

To solve g(x) = 2

The solutions are at the points of intersection of g(x) and y = 2

y = 2 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 2

If you draw the horizontal line using say (0, 2) and (2, 2)

Then g(x) intersects y = 2 at 3 places

Thus there are 3 solutions to g(x) = 2
