Answer:

A. No, because one x-value corresponds to two different y-values

Step-by-step explanation:

The rule of functions is that each domain value is unique and can't be repeated. In this problem, the x-value 2 is repeated twice, so you are correct.

Find the area of the following shape. You must show all work to receive credit.
Svetach [21]

Answer:

8

Step-by-step explanation:

Split up the shape into three smaller shapes: a triangle at the top, a 1 by 2 rectangle, and a triangle at the bottom left. The 1 by 2 rectangle has an area of 2. The triangle at the top has an area of (4*2)/2 = 4, and the triangle at the bottom right has an area of (2*2)/2 = 2.

Therefore, the total area of the shape is 2 + 4 + 2 = 8

Hope this helped!

Question 5 (Fill-In-The-Blank Worth 1 points)
Airida [17]

Answer:

The x-coordinate of the solution to this system of equations is <u>1</u>.

Step-by-step explanation:

Given,

6x - 5y = 5\\\\3x + 5y = 4

We have to find out the x-coordinate of the equation.

Solution,

Let 6x-5y=5\ \ \ \ equation\ 1

Again let 3x+5y=4\ \ \ \ \ equation \ 2

Now using elimination method we will solve the equations.

For this we will add equation 1 and equation 2 and get;

(6x-5y)+(3x+5y)=5+4\\\\6x-5y+3x+5y=9\\\\9x=9

Now on dividing both side by '9' we get;

\frac{9x}{9}=\frac{9}{9}\\\\x=1

Hence The x-coordinate of the solution to this system of equations is <u>1</u>.
