Answer:
72 degrees
Step-by-step explanation:
Slope
y=-(7/8)x+105
plug in 72 for the y
72=-(7/8)x+105
-177=-(7/8)x
72 = x
Answer:
0.67
Step-by-step explanation:
2/3 = 0.6666
0.6666 rounded to the nearest hundredth = 0.67
Answer:
4
Step-by-step explanation:
"4" is the number of variable terms that are in the expression 3x3y + 5x2 _ 4y + z + 9. The four variable terms in the expression are "xy", "x^2", "y" and "z". I hope that this is the answer that you were looking for and the answer has actually come to your desired help. If you need any clarification, you can always ask.
Ok so basically solve for y
x-y=12
27+3y=2x
27+3y=2x
subtract 3y from both sides
27=2x-3y
2x-3y=27
x-y=12
multiply by -2
-2x+2y=-24
add them
2x-3y=27
<u>-2x+2y=-24 +</u>
0x-1y=3
-y=3
y=-3
y coordinate is -3
2.
y=2x+14
-4x-y=4
y=2x+14
subtract 2x from both sides
y-2x=14
mulitply both sides by -2
-2y+4x=-28
add the 2 equations
-2y+4x=-28
<u /><u>-y-4x=4 +</u>
-3y+0x=-24
-3y=-24
divide both sides by -3
y=8
y coordinate is 8
1. y coordinate is y=-3
2. y coordinate is y=8<u>
</u>
