Answer:
x = 2 - 5
, x = 2 + 5
Step-by-step explanation:
x² - 4x = 71
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = 71 + 4
(x - 2)² = 75 ( take the square root of both sides )
x - 2 = ± 
= ± 5 ( add 2 to both sides )
x = 2 ± 5
then
x = 2 - 5 , x = 2 + 5
Answer:
A) (0,0)
Step-by-step explanation:
1.) graph the equation, 3x+2y = x+y
2.) the line intersects (0,0) on the coordinate plane
(7^5 * 7^3)^4 * 7^-2 / 7^-7 * 7^20
= (7^8)^4 * 7^-2 / 7^(-7 + 20)
= 7^32 * 7^-2 / 7^13
= 7^(32 - 2) / 7^13
= 7^30 / 7^13
= 7^(30 - 13)
= 7^17
I’m not sure but one of the numbers could be 1 and the other could be 0.5. These are possible answers that could go in the boxes. I got this because I knew that I had to get a number that’s less than 10. So when you do 8+1 you get 9 which is less than 10. I picked 0.5 because it said in the question we can’t pick the same number so I picked a decimal. When you do 8+0.5 you get 8.5 which is less than 10.
Hope this helped
