Wendi is 6 years older than Zaviel. The sum of their ages is 30. Which of these systems of equations can be used to find Wendi's age (w) and Zaviel's age (z)?

The system of equations for the ages of Wendi and Zaviel can be obtained as  x = y + 6 and x + y = 30 respectively.

What is a system of linear equations?

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

Suppose the age of Wendi and Zaviel be x and y respectively.

Then, the equation for their age can be written as,

x = y + 6

And, the equation for the sum of ages is given as,

x + y = 30

Hence, the equations that represent the given case are x = y + 6 and x + y = 30 respectively.

Answer: For Wendy’s age you can’t do 30-6=24 and then for Zaviel’s you can do 24-6=18 so Wendy is 24 years old and Zaviel is 18 years old.
30-6=w
W-6=z
30-6=24(w)
24-6=18(z)

multi-step equations

y = 2

Step-by-step explanation:

This equation can be solved three steps, classifying it as a multi-step equation.

To solve, you need to get the constants on one side and the variables on the other and then isolate the variable. These steps are illustrated below.

3y + 2 = 2y + 4 Subtract 2y from both sides of the equation.

y + 2 = 4 Subtract 2 from both sides of the equation.

y = 2

Which of the following correctly describes the graph of this function?

Answer: The graph of the function is symmetric about the y-axis.

Explanation:

Symmetric about the y-axis means that the graph can be reflected over, in this case the y-axis, without altering it. Your function is able to do this! I’ve attached a picture of the function so that you can visualize what I wrote.

482 – 412 + 286 - 12 x 204solve​

70,176

Step-by-step explanation:

Given that

482 - 412 + 286 - 12 × 204

We need to solve the above equation

= 482 - 412 + 286 - 12 × 204

= 70 + 286 - 12 × 204

= 356 - 12 × 204

= 344 × 204

= 70,176

Hence, the answer to the given equation is 70,176
