Answer:

x = 20

Step-by-step explanation:

Using the vertical angle theorem, you will find that 7x - 99 = 2x + 1.

7x - 99 = 2x + 1

+99 both sides

7x = 2x + 100

-2x both sides

5x = 100

÷5 both sides

x = 20

The answer is x = 20.

Question 3
Elan Coil [88]

Answer:

Domain:  -3\leq x\leq 1

Range:  -4\leq y\leq 0

Step-by-step explanation:

If you find the coordinate of the graph you can get the domain and range

(-3,0), (-2,-4), (-1,-2), (0,0), (1, -4)

Now that we have that find the domain and range

Domain -  x coordinate

Range - y coordinate

Domain: (-3, -2, -1, 0, 1)

Range: (-4, -2, 0)

Since the domain ranges from -3 to 1 you can use the inequality -3\leq x\leq 1 to represent the domain and -4\leq y\leq 0 for the range
