Answer:
Step-by-step explanation:
A line parallel to the x-axis is a horizontal line. A horizontal line will be in the form y = a constant. Since this line must pass through the point (4, 2), then the equation of the line is y = 2.
Answer: C
Step-by-step explanation:
7* w = 7w
7(w) = 7w
7+w = 7 + 1 w
7w = 7w
Alright!
1/4 = 0.25
.25(-12x+16) 7(-x-2)
(-3x + 4)(-7x-14)
21x^2 + 14 x - 56
Do you want me to find the roots or is this enough?
You can do a lot of things with the question you asked, you need to be more specific.
Answer:
x>-4
Step-by-step explanation:
Divide by negative 4 on both sides, and since its a negative, you have to flip the inequality sign, so it comes out to be x> -4
Answer:
You use cotx = cosx/sinx.
Step-by-step explanation:
I guess you mean cotx sinx = cosx.
You substitute the identity cotx = cosx / sinx:
cotx sinx = (cosx / sin x) * sin x
The sin x ' s cancel to give cosx.
