Answer:
No
Step-by-step explanation:
parallel= same gradient
y2-y1/x2-x1= gradient
M: 7-5/3.5-1
=2/2.5
=0.8
N: 10-7/7.5-4
=3/3.5
=0.86 (2DP)
no, the gradients are not the same, so therefore the lines m and n are not parallel.
Hope this helps:)
Answer:
A)
Step-by-step explanation:
To find the answer we must solve each of the systems separately. Starting with the first one:
x + y = 2
2x - y = 10
We must find what x or y is equal to and then replace it in the second equation. I'll go with y as it seems easier:
x + y = 2
y = 2 - x
Now that we found y we replace it in the second equation this way. Be careful with the signs, the minus with change our signs:
2x - (2 - x) = 10
2x - 2 + x = 10
3x = 12
x = 12/3
x = 4
Now that we have x, we replace the variable with its value in one of the equations. Again, for simplicity I'll go with the one that seems easier.
4 + y = 2
y = 2 - 4
y = - 2
the answer is 0.97 i hope I helped
