Answer:
Perpendicular...They have opposite slopes
Step-by-step explanation:
You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
Answer:
4
Step-by-step explanation:
2x + 5y = 34
x+2y = 14
Multiply the second equation by two to create like terms for one variable.
2(x+2y = 14)
2x + 4y = 28
2x + 5y = 34
2x + 4y = 28 -- Subtract.
y = 34.28 = 6
Solve for x
x + 2(6) = 14
x + 12 = 14
x = 2
Check:
2 + 2(6) = 14
2 + 12 = 14
14 = 14
Answer:
X = 2
Y = 6
