-10.
(11-7x)^1/4 =3
(11-7x)=81
-7x=70
X=-10
F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry
There are NO SOLUTIONS.
Substitute the first equation for y in the second equation. You can see it does not work. 6 does not equal 8. Therefore there are no solutions.
Answer:
2912
Step-by-step explanation:
Your question wording is a little confusing but here's the steps:
She drinks 56 glasses of water each week.
