Answer:
x=14 , y = 21
Step-by-step explanation:
y=x-7...............1
5x+2y=7......2
reset eqn .....2
2y=-5x+7
so; y=-x-7 ×5
2y=-5x+7 ×1
5y = -5x -35
2y = -5x +7
5y-2y = -5 + 5 -35-7
<u>3y</u> = - <u>42</u>
3 3
y = 14
sub y=14 into eqn ...........1
y = -x -7
14 = - x -7
14 +7 = - x
-21 = x
x = 14 , y =-21
Answer:
2(5)+5=15
Step-by-step explanation:
1. you have the equation 2b+c
2. then you add the numbers for c and b
3. so b=5 and c=5
4. once you add it into the problem then you get 2(5)+5 make sure you remember to times 2 x 5
5. then you do PEMDAS
6. you do multiply so 2x5 is 10
7. then do 10+5 and you get 15 as your answer.
The slant would be greater than the height because it is the hypotenuse and it is always greater than the legs.
Hope this helps
Im not sure but it think its 410 mile long, idk double check by changing it into eighths

Points on given line = (-12,-2) and (0,-4) because you can see them on the graph. Then draw a parallel line thru (0,6)
To get from (0,-4) to (0,6) your x stays constant and your y coordinate increased by 10. So your new point will do the same in relation to (-12,-2) the x will stay constant at -12 and your y will increase by 10 to +8.
So the answer is A (-12,8)
You can check this because parallel lines have the same slope so
y2-y1/x2-x1 should be equal for both lines.
Line 1: -4 - (-2) / 0 - (-12) = -2/12 = -1/6
Line 2: 6 - 8 / 0 - (-12) = -2/12 = -1/6
