Answer:
x = 20
Step-by-step explanation:
The two angles are verticals angles and vertical angles are equal
7x -99 = 2x+1
Subtract 2x from each side
7x-99-2x =2x+1-2x
5x-99 =1
Add 99 to each side
5x-99+99 = 1+99
5x =100
Divide each side by 5
5x/5 =100/5
x = 20
To find out how much tax they give you, you would need to subtract $4.88 from $8.35 which would be $3.46 and so $3.46 would be the tax.
Answer:
1/3

-8 - -6 = -2
-2 - 4 = -6
-2/-6 = 2/6 = 1/3
Answer:
Step-by-step explanation:
By looking at the graph I notice an open circle at (-4, -5) which means the function is not evaluable at -4, this restricts the domain.
The Domain of a function represents the set of values for which the function has an output.
The Range of a function is the set containing all the possible values associated with all input.
Domain in interval notation: (-4, 3]. The parenthesis denotes that the interval does not contain the extreme point -4. The brackets are the opposite.
Domain in set builder notation:
Range in interval notation: (-5, -3]
Range in set builder notation:
