Answer:
X=60
Step-by-step explanation:
Hello There!
The angle labeled 80 and the angles labeled x and 20 are alternate interior angles meaning that they are congruent
So
80=20+x
step 1 subtract 20 from each side
80-20=60
we're left with
x=60
Answer:
The amplitude is 4
Step-by-step explanation:
Recall that the amplitude of a harmonic form like this one based on the cosine function is the absolute value of the coefficient that multiplies the function. In our case that coefficient is 4.
So the amplitude of this function is "4".
Slope intercept y=mx + b, add y to both sides in your equation. Y=4x, slope intercept. Graphing should be easy, just plug in x intercepts
Hi!
The graph "x = 78" represents a vertical line passing through the point (78, 0).
Parallel lines always have the same slope, and for this equation a vertical line has an "undefined" slope.
Perpendicular lines have opposite inverse slopes. A line that's perpendicular to a vertical line is, of course, a horizontal line. Horizontal lines have a slope of 0.
Parallel to the equation: undefined
Perpendicular to the equation: 0
