They are vertical angles so you need to make the following equal
7y=5y+36 and 3x-21=2x+4
Solve for y and then x
7y=5y+36
Subtract 5y on both sides to get
2y=36
Then divide by 2 on both sides to Get y=18
For 3x-21=2x+4,
Subtract 2x on both sides to obtain
x-21=4
Then add 21 to both sides to get
x=25

Answer:
If one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480
Step-by-step explanation:
Given that:
The absolute value function:
To calculate the position of the buoy where the river bottom is 20 feet below the surface, we equate the absolute value function to the negative value of 20 feet and then solve it for h.
d(h) = -20
Let us add the sum of 50 on both sides, then:
By multiplying 6 on both sides, we have:
|h - 300| = 30 (6)
|h - 300| = 180
We can attempt the above expression by rewriting it as two equations:
h - 300 = 180 or h - 300 = - 180
Let us add 300 to both sides from the two expressions above:
h - 300 + 300 = 180 + 300 or h - 300 + 300 = -180 + 300
h = 480 or h = 120
Thus, if one buoy is placed 120 feet away from the left shore, then the distance of the second buoy from the left shore = 480
A and D seem to be the only correct ones. Hope this helps
x = -3 or x = -2
Step-by-step explanation:
x² + 5x + 6 = 0
(x + 3)(x + 2)
x = -3 \/ x = -2
