x = 7
y = 8
All I did was assume x was 7 and y was 8. I added 4, 6, 7, 8, and 10 together. I got 35. Then, I divided by five (since that's how many numbers are shown) and I got 7 for the mean. 7 is the median, and the 7 is the mean gotten from 4, 6, 7, 8, and 10. Therefore, x must equal 7 and y must equal 8.
1) equation given: 0 = x^2 - 6x + 4
2) transpose 4: - 4 = x^2 - 6x
3) complete squares: - 4 = (x^2 - 6x + 9) - 9
4) transpose -9 and factor the square trinomial x^2 - 6x + 9:
- 4 + 9 = (x - 3)^2
5) combine like terms: 5 = (x - 3)^2
6) take square root on both sides: x - 3 = +/- √5
7) transpose - 3: x = 3 +/- √5
Answer: the two solutions are x = 3 - √5 and x = 3 + √5
40ft hope this hellped ask again
It’s very easy to just times 40×10 and you get 400 and add $100 and you would get 500 so it would be 10 weeks
Answer: 10 weeks
Answer:
x=4 orx=- 8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

Step 2: Subtract -x^2+32 from both sides.
