Answer:
parallel
Step-by-step explanation:
The "work" is to recognize that both equations describe horizontal lines. All horizontal lines on the Cartesian coordinate grid are parallel.
_____
<em>Additional comment</em>
y = constant . . . . . a horizontal line (y=0 is the x-axis)
x = constant . . . . . a vertical line (x=0 is the y-axis)
__
If you wanted to go to the trouble, you could compare the equation ...
y = constant
to the slope-intercept form ...
y = mx +b
Your comparison would note that m=0. That is, the slope is zero, so the line is horizontal. All lines with the same (zero) slope are parallel.

<h3>Answer: 4 meters (choice C)</h3>
==========================================
Explanation:
h = height of trapezoid (in meters)
b1 and b2 are the parallel bases, which are b1 = 4.6 and b2 = 6.1
A = 21.4 is the area of the trapezoid
-------
Plug those values into the area formula of a trapezoid. Isolate h
A = h*(b1+b2)/2
21.4 = h*(4.6+6.1)/2
21.4 = h*(10.7/2)
21.4 = h*(5.35)
21.4 = 5.35h
5.35h = 21.4
h = 21.4/5.35 ...... divide both sides 5.35
h = 4
The height is 4 meters
Answer:
D
Step-by-step explanation:
It isn't the most efficient way to solve the problem, but the other 3 are incorrect.
C should be the answer
