Answer:
$50.59
Step-by-step explanation:
First you take off 20% from 68. ( 68 * 0.2 = 13.6 )
68- 13.6 is 54.4
for the sales tax, you take out 7% of 54.4
54.4 * 0.07 = 3.808
54.4-3.808 = 50.59!
<u>Answer:</u>
The mid-point is (7.5, 8.5).
<u>Step-by-step explanation:</u>
We are given two points (9,9) and (6,8) as the endpoints for a line segment and we are to find the midpoint of this segment.
We know that the formula for finding the mid point is:
<em>Mid point = 
</em>
So substituting the given values of the coordinates of the endpoints in the above formula to get:
Therefore, the mid-point is (7.5, 8.5).
Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x - 10 = 2
3x = 12
x = 4
(4, -2)
Answer:
(x + 3)^2 + (y - 2)^2 = 9
Step-by-step explanation:
<u>Equation for a circle: (x – h)^2 + (y – k)^2 = r^2</u>
<u />
<u>Step 1: Determine what h, k, and r are</u>
<em>h is the x value of the point: -3</em>
<em>k is the y value of the point: 2</em>
<em>r is the radius of the circle: 3</em>
<u>Step 2: Plug in and solve</u>
(x – h)^2 + (y – k)^2 = r^2
(x – (-3))^2 + (y – (2))^2 = (3)^2
<em>(x + 3)^2 + (y - 2)^2 = 9</em>
<em />
Answer: (x + 3)^2 + (y - 2)^2 = 9
