Let f (x) = 2x - 1, g(x) = 3x, and h(x) = x2 + 1. Compute the following: f (h(x)) and. g (f (x))

1 answer:

7 0

F((h(x)) = 2(x^2 + 1) - 1 = 2x^2 + 1 (replace the x in f(x) by h(x))

g ( f(x)) = 3(2x - 1) = 6x - 3 (replace the x in g(x) by f(x))

Determine if the lines are parallel, perpendicular, or neither 10x+5y=-5 and y=-2x+6

Ksenya-84 [330]

If they are parallel they will have the same slope , m

So in y = mx + c, if there are two equations which both have the same m value they will be parallel.
If the lines are perpendicular they'll have slopes like this: 1/2 to -2/1 - where they flip and a negative gets added.

In the equations: 10x + 5y = -5 , and y = -2x + 6
We can rearrange 10x + 5y = -5 to be in the form y = mx + c
10x + 5y = -5
5y = -5 - 10x
y = -1 - 2x
y = -2x - 1

Since y = -2x - 1 and y = -2x + 6 both have the same slope of -2 they are parallel!

Suppose Larry has 16 books and Pat has x books. (Larry still has at least 3 more than Pat.)

zimovet [89]

Answer:

13 ≥ x

Step-by-step explanation:

Larry = 16
Pat = x

Larry has at least 3 more than Pat

16 ≥ x + 3

Simplified

16-3 ≥ x + 3 - 3
13 ≥ x
