Answer:
Yes, lines CD & AB are perpendicular
Step-by-step explanation:
AB slope: y = -12/8x + 7
CD slope: y = 6/9x - 6
Once the slopes are simplified:
AB: -3/2
CD: 2/3
Hope this helps!
Answer:
n = 10
Step-by-step explanation:
The triangles are equal by SSS theorem, therefore the 2 angles given with a variable must be equal.
Answer:
(-2.5, -4.5)
Step-by-step explanation:
Answer:
Multiply each equation by the coefficient of y in the other one.
Step-by-step explanation:
(1) 6x + 5y = 2
(2) 4x + 2y = 8
Multiply each equation by the coefficient of y in the other one.
Multiply (1) by 2 and (2) by 5.
(3) 12x + 10y = 4
(4) 20 x + 10y = 40 Subtract (3) from (2)
8x = 36 Solve for x
x = 9/2
Answer:
y=x^2-17x+72
Step-by-step explanation:
You have to Work backwards to find the factors from the roots, then multiply the factors together
