Answer:
63 degrees
Step-by-step explanation:
180 = 117 = 63
Answer: x = 4.5
Step-by-step explanation:
1) Reorder the terms:
3x = -9 + 5x
2) Solving
3x = -9 + 5x
3) Solving for variable 'x'.
4) Move all terms containing x to the left, all other terms to the right.
5) Add '-5x' to each side of the equation.
3x + -5x = -9 + 5x + -5x
6) Combine like terms: 3x + -5x = -2x
-2x = -9 + 5x + -5x
7) Combine like terms: 5x + -5x = 0
-2x = -9 + 0
-2x = -9
8) Divide each side by '-2'.
x = 4.5
9) Simplifying
x = 4.5
The average is (0.76+0.88) / 2 = 1.64 / 2 = 0.82
Answer:
y = a 
+ b x + c .
Step-by-step explanation:
Also (How to do it!):
We can find the vertex of a quadratic equation with these steps:
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
3(x + 4) = x/2 - 8
First, we can multiply both sides by 2:
6(x+4) = x - 16
6x + 24 = x - 16
Isolate x:
5x = -16 - 24
5x = -30
x = -6
