Answer:
Step-by-step explanation:

- 5/8x + 25 = 3/8x + 15 + 1/4x
- 5/8x + 10 = 3/8x + 2/8x
- 5/8x + 10 = 5/8x
- 10 = 0
Make a system of equations and solve for each variable.
3m+8v=53
5m+2v=26
m= movie cost
v= game cost
multiply the bottom equation by 4(combination method)
3m+8v=53
20m+8v=104. Subtract
-17m = -51
m= 3
Plug back into one of the equations
5(3)+2v=26
15+2v=26
2v=11
v=5.5
m=$3
v=$5.5
Easily we can use formula y=(x-h)^2 +k
as equation of a parabola if vertex was (h,k):
Y=(x-1)^2 + 3
and maybe node (2,6) is incorrect for this vertex of a parabola!!!
"Calculate the square root of 10 (√ 10) to 4 decimal places.<span>Find the perfect square number closer to 10. 32 = 9 and 42 = 16, so take 3.Divide 10 by 3. 10÷3 = 3.33 (you can round off the answer)Average 3.33 and 3. ( 3.33 + 3)÷2 = 3.1667."

(6^-2)^2 = 1/1296 = 0.0007716049382716 hope this is what you were looking for. the math is right tho for (6^-2)^2 most calculators can do this easy just do 6^-2 then after just do ^2
