Answer:
5a + 9 + 2b
Step-by-step explanation:
(3a + 2a) + (4 + 5) + (b + b)
5a + 9 + 2b
I hope this helps you
y= 4x^2-19x-5
4x +1
x -5
y=(4x+1). (x-5)
4x+1=0 4x= -1 x= -1/4
x-5=0 x= 5
Answer:
7y-4x.
Step-by-step explanation:
I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.
-3(2x- y) + 2y + 2(x+y)
= -6x+3y + 2y+2x+2y
= -6x+2x+3y+2y+2y
= -4x+7y.
For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:

Clearing d we have:
Answer:
A functions that would best model the situation above is:
D square root
