Answer:
Step-by-step explanation:
z = 3
2y + z = 1
2y + 3 = 1 {substituting z =3}
2y = 1 -3
2y = -2
y = - 2/2
y = -1
2x +3y +2z = 13
2x + 3 * (-1) + 2*3 = 13 { {substituting z =3} and y = -1}
2x -3 + 6 =13
2x + 3 = 13
2x = 13 - 3
2x= 10
x = 10/2
x = 5
Y≥-9x-6.5... is what I think you're looking for, though I'm not quiet sure.
Answer:
- Y=2+√4x+28 -
Step By Step:
Ok so, the original expression is 2(x - 2)² = 8(7 + y).
First you Rewrite the expression as 7 + y = (2/8)*(x-2)² = (1/4)*(x-2)²
So know its; y = (1/4)(x-2)² - 7
To find the inverse, switch x and y, and solve for y.
x = (1/4)(y-2)² - 7
Then you Multiply through by 4
4x = (y-2)² - 28
(y-2)² = 4x + 28
y - 2 = √(4x + 28)
y = 2 +/- √(4x + 28)
Answer:
80 ounces
Step-by-step explanation:
There are 16 ounces in a pound. So to convert from pounds to ounces, you multiply 5 by 16, which is 80.
