<span>Reorder the terms:
-2.3(-1.2 + x) = -9.66
(-1.2 * -2.3 + x * -2.3) = -9.66
(2.76 + -2.3x) = -9.66
Solving
2.76 + -2.3x = -9.66
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2.76' to each side of the equation.
2.76 + -2.76 + -2.3x = -9.66 + -2.76
Combine like terms: 2.76 + -2.76 = 0.00
0.00 + -2.3x = -9.66 + -2.76
-2.3x = -9.66 + -2.76
Combine like terms: -9.66 + -2.76 = -12.42
-2.3x = -12.42
Divide each side by '-2.3'.
x = 5.4
Simplifying
x = 5.4</span>
Xy = 216
x = 216/y
2x + 2y = 60
2(216/y) + 2y = 60
432 + 2y^2 = 60y
2y^2 - 60y + 432 = 0
y = 18 , y = 12
if y = 12
x = 216/12
x = 18
length = 18
width = 12
The answer I got was y=-12x+43.
Hope this helps!
Answer:

Step-by-step explanation:
Vertex form:
where:
is the vertex
is some constant
Given:
- vertex = (-4, -1)
- point on parabola = (-2, -3)
Substitute given values into the formula to find
:





Therefore, the equation of the parabola is:

Answer:
-1/5
Step-by-step explanation:
We know that a^b * a^c = a^(b+c)
(−5)^5(−5)^−6
(-5) ^(5+-6)
(-5)^-1
We know that a^-b = 1/a^b
1/(-5)^1
1/-5
-1/5
