Answer:
(x-5) (x+1)
Step-by-step explanation:
x^2 - 4x - 5
Factor
What 2 numbers multiply to -5 and add to -4
-5*1 = -5
-5+1 = -4
(x-5) (x+1)
Answer:
Your answer of coplanar is correct
Step-by-step explanation:
A skew line are 2 lines that aren't parallel and do not intersect.
Since there are arrows on either end of AC and RS , it mean those lines continue, and they will eventually intersect.
It is also not the other 2 clearly, since they do intersect and they don't make a 90° angle
So yes,
The answer is Coplanar
Hope this helps.
Answer:
Step-by-step explanation:
first number = x
second number = y
x = y - 4
2y = 3x + 19
substitute x to the second equation
2y = 3(y-4) - 4
2y = 3y -16
-y = -16
y = 16
Go back to first equation
x = y - 4
x = 16 - 4
x = 12
Answer:
f(-2) = -8
Step-by-step explanation:
f(x) = 2x - 4
=> f(-2) = 2(-2) - 4
=> f(-2) = -4 - 4
=> f(-2) = -8
