Answers

Answer 1

Answer: -8x - 5y = 1
when x = 2
-8(2) - 5y = 1
-16 - 5y = 1
5y = -16 - 1 = -17
y = -17/5

There are two boards, a and b. The total length of both is 28 feet. Board b is at least 5 feet longer than board a, but the difference is not more than 12 feet. What are the possible lengths of the two boards?

Answers

Answer:

Step-by-step explanation:

Let a represent the length of board a.

Let y represent the length of board b.

The total length of both is 28 feet. This means that

a + b = 28

Board b is at least 5 feet longer than board a. This means that

b ≥ a + 5

The difference between both boards is not more than 12 feet. This means that

b - a < 12

Substituting a = 28 - b into b ≥ a + 5, it becomes.

b ≥ 28 - b + 5

2b ≥ 28

b ≥33/2

b ≥ 16.5

16.5 - a < 12

4.5 < a

a > 4.5

The possible lengths of board a is

8 to 11.5 feet

The possible lengths of board b is

16.5 to 20 feet

Answers

Answer:

Number of gallons of water produced each cay by the company = 7200 gallons

Number of 1 gallon bottles put in a carton = 8

Number of cartons needed to hold all the 1 gallon bottles in a day = 7200/8

= 900

So 900 cartons are required to hold all the one gallon bottles produced by the company in a day. I hope the procedure is clear enough for you to understand. It is also important to carefully look at all the details that are provided in the question.

Answer:

900 cartons are needed

Step-by-step explanation:

7200/8=900

The quotient is equal to :

$- {x}^(2) - 14x + 28$

remainder :

$- 63$

Solution is in attachment ~

Answer:

${ \rm{( {2x}^(2) - {x}^(3) - 18 {x}^(2) - 7) / (x + 2) }}$

• now, (x + 2) is the factor.

• let's find the value of xfrom the factor:

${ \rm{x + 2 = 0}} \n { \underline{ \rm{ \: \: x = - 2 \: \: }}}$

• let's substitute for xinto the quotient:

${ \rm{f(x) = {2x}^(2) - {x}^(3) - {18x}^(2) - 7 }} \n \n { \rm{f( - 2) = 2 {( - 2)}^(2) - {( - 2)}^(3) - 18 {( - 2)}^(2) - 7 }} \n \n { \rm{f( - 2) = 8 +8 - 72 - 7}} \n \n { \boxed{ \boxed{ \pmb{answer \: \dashrightarrow \: \: {}^( - ) 63 \: \: }}}}$
