The axis of symmetry is found within the set of parenthesis with the x. If our h value of the vertex is -4, then the axis of symmetry is x = -4. D is that choice. Cannot graph it here, but your vertex is sitting at (-4, 4), it's an upside down parabola, and some other points on this graph are (-5, 0), (-3, 0), (-6, -12), (-2, -12). You could graph it using those points and the vertex without a problem, I'm sure.
Answer: C. 84
Step-by-step explanation:
In triangles ABD y BCD:
- AD=CD
- Angle BAD = angle BCD
- BD common side
THEN the triangles are equal because they have two sides and the angle opposite the longest side respectively equal.
CBD = ABD = 42 because the triangles ABD y BCD are equal
ABC = CBD+ABD = 42+42= 84
Answer:
Slope = 5.
y-int = (0, -2).
Step-by-step explanation:
y = 5x - 2
The slope intercept form is
y = mx + b where m = the slope and b = the y-intercept.
So here, the slope = 5 and the y-intercept is where y = -2. That is the point (0, -2).
Answer:
WZX = 110
y = 19
Step-by-step explanation:
We can create the following equation to solve for y.
Reduce
4y = 76
y = 19
We then plug into 4y + 34 to get angle
WZX = 110
