-2 1/7 is the correct answer.
The equation for the table is f(x)=3x+1 so I don’t know for a but for b it would be f(x) because 1 is greater than 5.
20 * .10 = 2 <em>(2 = 10% of 20)</em>
20 + 2 = 22
20 x .07 = 1.4 <em>(1.4 = 7% of 20)</em>
20 + 1.4 = 21.4
The price of a 20$ haircut with a 10% tax would be $22.
The price of a 20$ haircut with a 7% tax would be $21.40.
You would use 539 and square it on you cal. just once. Then once you do that the answer is not going to be a whole number it is going to have a decimal, so the answer would be 23.22.
X = 19.
Explanation:
This expression is vertical from the angle 135, meaning it is congruent. With that being said, we would need to find what 7 multiplies by to give us 2 less than 135, which would be 133. Because 133 divided by 7 equals 19, x = 19. If we plug this in, we get the following equation: 7(19) + 2 = 135.
