$y = x^2 + 2x + 1$

It's already a square; we don't need to add anything to complete the square.

$y = (x + 1)^2$

That's a vertex at x = -1. The corresponding y is y=0.

Answer: Vertex at (-1,0)

As for the other questions cut off there, the axis is the vertical line x = -1 and the range is y ≥ 0.

18. what Gives the missing value in 2/5 = x/30?

Korolek [52]

X is equal to 12
This is because 5 was multiplied and 6 making 30. So you have to multiply 2 and 6 making x 12. Hope that makes sense

A card is picked from a standard deck of 52 cards. determine the odds against and the odds in favor of selecting a 10

bulgar [2K]

<span>You are given a card is picked from a standard deck of 52 cards. You are asked to determine the odds against and the odds in favor of selecting a 10. There are a total of 52 cards in a deck. In selecting a 10 of any card, you get four 10's in all kinds of cards (spade, clover, heart, diamond). So to solve for the probability of the odds in favor of selecting a 10, divide four by 52 and you get 10/52 or 5/26. To solve for the probability of the odds against selecting a 10, subtract four from 52 and you will get 48 and then divide it by 52 so 48/52 or 12/13. </span>

If f(x)= -x+6x-1 and g(x)=3×-4x-1, find (f-g)(x)

Alex787 [66]

-x + 6x - 1 - (3x - 4x - 1)

-x + 6x - 1 - 3x + 4x + 1

5x - 3x + 4x - 1 + 1

(f-g)(x) = 6x
