What are the values of k that make 2x^2 + kx + 11 factorable?

1 answer:

8 0

Well K is the sum of two integers so the product equals 2*11, as a Hero pointed out:
ac=2*11=22 k=sum of two integers so now it = to 22

I hope this helps :D

Answer:

INSTRUCTION FOLLOWED: write the sum as a mixed number where the fractional number is less than one.

5/5 out of the 7/5 make ONE whole while 2/5 is left over.

The ONE whole is added to nine to make 10 and the remaining 2/5 is also added to the 10 hence 9 7/5 = 10 2/5

HELP PLEASE!!

zhenek [66]

Answer:

y = 1/2x + 1.

Step-by-step explanation:

Use the point-slope form of a straight line:

y - y1 = m(x - x1) (where m=slope and(x1,y1) is a point on line).

y - 3 = 1/2(x - 4)

y = 1/2x - 2 + 3

y = 1/2x + 1.

daser333 [38]

We have been given a table of overnight low temperature for a four-day period. We are supposed to give a possible temperature for Wednesday.

We are told that the low temperature on Wednesday was between the second and third highest temperature.

Let us place our given temperatures from least to greatest order.

Sunday (-11), Thursday (-8), Friday (7), Sunday (18)

We can see that second and third highest temperatures are -8 and 7 respectively.

Any number between -8 and 7 will be a possible temperature for Wednesday. 3 can be a possible temperature for Wednesday as 3 is between -8 and 7.

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Ostrovityanka [42]

Answer:

54 inches

Step-by-step explanation:

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Step 1

We would be converting the length of the Royal's pet snake to inches

1 foot = 12 inches

8 feet = x

Cross Multiply

x = 8 × 12 inches

x = 96 inches

Step 2

How many inches longer is Royal's snake?

This is calculated by subtracting the length of the Royal's pet snake from the least length

= 96 inches - 42 inches

= 54 inches

Therefore, the Royal's snake is 54 inches longer
