AB ≅ DC and AD ≅ BC
slope of BC = slope of AD (m = 1/3), slope of AB = slope of DC (m = 3/1)
opposite sides are congruent and parallel so ABCD is a parallelogram.
Answer: parallelogram

Answer:
C. y = 2x + 8
Step-by-step explanation:
✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):
Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))
Slope (m) = 16/8
m = 2
✔️Find the y-intercept (b):
To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b
Thus:
20 = 2(6) + b
20 = 12 + b
20 - 12 = b
8 = b
b = 8
✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b
Thus:
y = 2x + 8
Answer:
Substitute 3x - 5 for y in the second equation.
Step-by-step explanation:
Generally, to solve the system of linear equations of x and y, the first step would be trying to eliminate x (or y).
Then turn the system into the equation of only y (or x).
Next, try to solve for y (or x).
Then substitute the solved y (or x) into the original system to work out x (or y).
**********
3 options (1 addition, 2 subtractions) do not eliminate x or y (x and y still exist after manipulation).
=> Remaining option relating substitution would be a reasonable choice.
I believe it would cost $10,329.
If you add all the feet together, you will get 939 ft. There are 3 ft in a yard, so you divide 939 ft by 3 to get the number of yards. Which is 313 yd. then you multiply that by 33 since each yard equals $33. And will get 10,329 as a result.
