Answer: D ( 7,3 7,6 7,9 7,12 7,15)

Step-by-step explanation:

A- (-4, 0, 7, 3, -7) There are no repeating domains, therefore, this is a function

B- (1, 3, 5, 7, 9) The domain does not repeat, therefore this is a function

C- (4, 8, 12, 16, 20) The domain does not repeat, therefore this is a function

D- (7, 7, 7, 7, 7) The entire domain repeats, therefore this cannot be a function

Correct answer is D ( 7,3 7,6 7,9 7,12 7,15)

Mister Lincoln by juices and water for the school picnic a pack of their juices box cost $5 about the six water bottles cost $3

Lady bird [3.3K]

Answer:

10 packs of juice and 15 packs of water was bought by Mr. Lincoln

Step-by-step explanation:

Mr. Lincoln buys juice and water for the school picnic. A pack of 8 juice boxes costs $5. A pack of 6 water bottles costs $3. Mr. Lincoln spends $95 for 170 juice boxes and bottles of water.

Solution:

Let x represent the number of packs of juice boxes bought by Mr. Lincoln and let y represent the number of packs of water bottles bought by Mr. Lincoln.

Each pack of juice cost $5 while each pack of water cost $3. Mr. Lincoln spends $95, therefore:

5x + 3y = 95 (1)

Each pack of juice contain 8 juice boxes and each pack of water contain 6 water bottles. Since 170 juice boxes and bottles of water was bought, therefore:

8x + 6y = 170 (2)

Solving equations (1) and (2) simultaneously. Multiply equation (1) by 2 and then subtract equation (2) from the result to get:

2x = 20

x = 10

Substitute x = 10 in equation (1):

5(10) + 3y = 95

50 + 3y = 95

3y = 45

y = 15

Hence 10 packs of juice and 15 packs of water was bought by Mr. Lincoln

Answer:

1 solution

no solution

infinitely many

1 solution

Step-by-step explanation:

1. 2.3x-7=-7

2.3x=0

x=0

2. 3x=5+3x

0x=5

x=5/0

That’s undefined

3. 40-4x=4(10-x)

40-4x=40-4x

They both are equal no matter what. So, infinitrly many

4. -7+x=-(x+7)

-7+x=-x-7

2x=0

x=0
