Answer:
Simplifying
(-4x + -2) + -1(13x + 1) = 0
Reorder the terms:
(-2 + -4x) + -1(13x + 1) = 0
Remove parenthesis around (-2 + -4x)
-2 + -4x + -1(13x + 1) = 0
Reorder the terms:
-2 + -4x + -1(1 + 13x) = 0
-2 + -4x + (1 * -1 + 13x * -1) = 0
-2 + -4x + (-1 + -13x) = 0
Reorder the terms:
-2 + -1 + -4x + -13x = 0
Combine like terms: -2 + -1 = -3
-3 + -4x + -13x = 0
Combine like terms: -4x + -13x = -17x
-3 + -17x = 0
Solving
-3 + -17x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + -17x = 0 + 3
Combine like terms: -3 + 3 = 0
0 + -17x = 0 + 3
-17x = 0 + 3
Combine like terms: 0 + 3 = 3
-17x = 3
Divide each side by '-17'.
x = -0.1764705882
Simplifying
x = -0.1764705882
Answer:
A. 32 degrees
Step-by-step explanation:
Here we have to use the rule.
m∠E = 1/2 (major arc - minor arc)
m∠E = 1/2 (212 - 148)
m∠E = 1/2 (64)
m∠E = 32 degrees
Answer: A. 32 degrees
Thank you
Answer:
The vertex of the quadratic equation is the point (4,2)
Step-by-step explanation:
we know that
The figure show a vertical parabola open downward
The vertex represent the maximum point of the graph
Looking at the graph
The maximum point of the graph is (4,2)
therefore
The vertex of the quadratic equation is the point (4,2)
