3x -3y = 6
or, 3(x -y)= 6
or, x-y =6/3
or, x-y = 2
or, x=2+y........eqn(i)
4x - 7y = 2
substituting the value of x from eqn(i)
or, 4(2+y) -7y = 2
or, 8 + 4y -7y = 2
or, -3y = 2-8
or, y = -6/-3
■ y=2
so in eqn(i)
x= 2+y
x= 2+2
■x = 4
Answer:
I don't think it's possible for this to be a decimal because the slope is positive 11.
Step-by-step explanation:
Use slope formula. x2-x1/y2-y1. Since we always go with the smaller x value we do 8-(-3) / 4-3/ We'll get 11 for 8-(-3) and we'll get 1 for 4-3/ so that leaves us with 11/1 which can't be simplified and has no decimal.
Answer:
80 degrees
Step-by-step explanation:
both intersections are the same, so we can count them as one. We notice that one line is a straight line compared to other so we can subtract 100 from 180 and get 80
291-2999=10376 square feet
Answer:
4.5
Step-by-step explanation:
6x + 42 = 18x - 12 (alternate angles)
or, 18x - 6x = 42+12
or, 12x = 54
or, x = 54/12
x= 4.5
