Answer:
C. x=2
Step-by-step explanation:
The axis of symmetry divides the parabola into two equal parts. FRom point x=-4 to x=8, the difference is 12 units and the centre is6 units on each side. Using a number line, the axis of symmetry is at point x=2
Answer:
The measure of the third angle is 117 degrees and the measure of the two equal angles is 31.5 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A geodesic dome is compromised of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of the third angle is 85.5 degrees more than the measure of either of the two equal angles. Find the measure of the three angles
we know that
An isosceles triangle has two sides and two equal interior angles
Let
x -----> the measure of the third angle
y ----> the measure of either of the two equal angles
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
![x=85.5\°+31.5\°=117\°](https://tex.z-dn.net/?f=x%3D85.5%5C%C2%B0%2B31.5%5C%C2%B0%3D117%5C%C2%B0)
therefore
The measure of the third angle is 117 degrees and the measure of either of the two equal angles is 31.5 degrees
Answer:
97/2
Step-by-step explanation:
x−9+x+2x−5=180
x−9+x+2x−5=180
x+−9+x+2x+−5=180
4x+−14=180
4x−14=180
4x−14+14=180+14
4x=194
4x/4 = 194/4
x = 97/2
You can use substitution here. First, get y alone:
14x + y = -4
subtract 14x from each side
y = -4 - 14x
Then, plug y into the second equation
-4 - 14x = 3x² - 11x - 4
then solve from there
Hope this helps :)
