Ok so you multiply 22 square and then do the same for 10, do the negative of the square of 22 and then subtract it from the 10 and you should get another negative and it should be b=x the value of both and finally you divide the b and the value by the square root . An example would be a=8 + b = c= 20 going through the process you would get the answer of 18.33. I know I didn't explain this correctly so here's a link to help you with math problems.
6 because 46-40=6. you do that because the total is 46 and something + 40 =46 so u subtract.
y = 1/7x + 4
1/7 * a2 = -1
a2 = -7
y = -7x + b
A = (-1, 5)
-7 * (-1) + b = 5
7 + b = 5
b = -2
<em><u>y </u></em><em><u>=</u></em><em><u> </u></em><em><u>-7x </u></em><em><u>-</u></em><em><u> </u></em><em><u>2</u></em>
Answer:
(2, -8)
Step-by-step explanation:
The answer is (2, -8) because when you reflect a point across the x-axis, the x-coordinate always remains the same, but the y-coordinate will change. In other words, the y-coordinate becomes the opposite (signs change). In this case, since the y-coordinate was positive 8, when you reflect the point across the x-axis, the y-coordinate will change to -8
