Answer:
parallel 2/3 slope
perpendicular -3/2
Step-by-step explanation:
in parallel lines the slope is the same
perpiticula lines are the opposite recipical
Make it y = mx + b
Subtract 7x to both sides
7x - 7x + y = 3 - 7x
Y = -7x + 3
The slope is -7, the y intercept is 3
Ok....
What am I supposed to answer here???
Answer:
x =9
Step-by-step explanation:
7x+3 = 6x + 12
x + 3 =12
x = 9
So both angles equal 66*
Δ(discriminent) = b²-4ac
Calculate Δ of: -2x² + 6x +13, where:
a= -2
b=6
c=13
THEN Δ = 6² - 4(-2)(13) = 36 -4(-26) = 36 +104 and Δ = 140
