Answer:

company A:  y= 40+8.5*(x)

company B: y=30+10.5*(x)

5 gigabytes of data would have to be used for company A and B to cost the same amount.

Step-by-step explanation:

  • let the cost be represented on y axis. so, the equation for company A is:
  • (for the first month) : y= 40+8.5*(x)

[common monthly charges are $40 and let x represent the number of gigabytes of data used. so, 8.5*x gives cost due to to total gigabytes. hence, i have added 40 and  8.5*x to represent the total cost for first month]

  • company B:

y=30+10.5*(x)

[obtain this also in the above mentioned manner]

  • the graph is uploaded in the attachment.
  • to know about number of gigabytes required to make the costs of both the company equal, we can directly observe in the graph where both the company's lines intersect and the get the corresponding x coordinate. this x coordinate represents the required number of gigabytes. or we can directly equate the above equations.[as shown below]

40+8.5*(x)=30+10.5*(x)

subtracting 30 from both sides,

10+8.5x=10.5x

subtracting 8.5x from both sides,

10=2x

dividing both the sides by 2.5,

5=x [since, 10/2 = 5)

  • therefore, 5 gigabytes of data would have to be used for company A and B to cost the same amount.

Choose all that give the correct expression for the quantity described. The difference of nine times a number x and the quotient
ohaa [14]

Step-by-step explanation:

We are to get the expression for the following statements;

1) The difference of nine times a number x and the quotient of that number and 5.

The product of nine and a number x is expressed as;

=9 \times x\\= 9x

The quotient of that number and 5.

= \frac{x}{5}

The difference between both expression;

9x - \frac{x}{5}

Hence, the difference of nine times a number x and the quotient of that number and 5 is expressed as 9x - \frac{x}{5}

2) Eight more than the quotient of twelve and a number n

Quotient of twelve and a number n is expressed as:

\frac{n}{12}

Eight more than the resulting function is;

\frac{n}{12}+8

Hence eight more than the quotient of twelve and a number n is expressed as \frac{n}{12}+8

3) The product of a number and the quantity 'six minus the number' plus the quotient of eight and the number.

Let the number be x:

six minus the number is expressed as;

6-x

product of a number x and the quantity 'six minus the number is;

x(6-x)

quotient of eight and the number is;

\frac{8}{x}

Taking the resulting sum of the last two expression

x(6-x) + 8x

Hence the product of a number and the quantity 'six minus the number' plus the quotient of eight and the number is expressed as;

x(6-x) + 8x

4) Sum of three consecutive even integers. 2x + (2x + 2) + (2x + 4).

Let the first even number be 2x

The consecutive even numbers are gotten by adding 2 to the preceding number. The two consecutive even integers are 2x+2 and 2x+2+2

the sum of three consecutive even integers is expressed as;

= 2x +(2x+2)+(2x+2+2)\\=  2x+(2x+2)+(2x+4)

C, or 5000(0.9)t is correct.

Multiplying by 0.1 would not make the car’s price go down by ten percent, but 90. Hence, C is correct.

during the 8-month shrimping season in the Gulf mexico, 325 shrimpers caught 4,913,977 pounds of shrimp and sold the shrimp $2 p
Hatshy [7]
STEP 1:
Find the $ total sold. Multiply total pounds by $2 sale price per pound.

=4,913,977 pounds * $2 a pound
=$9,827,954 total sold

STEP 2:
Divide the total sold above by the 325 shrimpers.

=$9,827,954 ÷ 325
=$30,239.858

Rounded to nearest dollar:
Each of the 325 shrimpers will take home $30,240.

Hope this helps! :)
