Answer:

y= -18

a= -18

Step-by-step explanation:

2y+3 = 3(y+7)

2y+3=3y+21

     -21     -21

2y-18=3y

-2y      -2y

-18=y

Answer:

Step-by-step explanation:

The slope of a graph is the rate of the graph

Josh's equation is given as:

[tex]\mathbf{y = 2.5x}[/tex]

A proportional equation is represented as:

[tex]\mathbf{y = mx}[/tex]

Where m represents the rate.

So, by comparison:

[tex]\mathbf{m = 2.5}[/tex]

The points on Marlo's graph are:

[tex]\mathbf{(x,y) = (0,0)(40,8)}[/tex]

So, the rate is calculated as:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

This gives

[tex]\mathbf{m = \frac{8 - 0}{40 - 0}}[/tex]

[tex]\mathbf{m = \frac{8}{40}}[/tex]

[tex]\mathbf{m = 0.2}[/tex]

So, we have:

[tex]\mathbf{m = 2.5}[/tex] --- Josh

[tex]\mathbf{m = 0.2}[/tex] --- Marlo

2.5 is greater than 0.2

Hence, Josh makes birds at a faster rate.

If you graph the data for Josh and Marlo on the same coordinate plane, Josh's graph will have a steeper line

You may determine the slope of the line by determining the rise and the run using two of the line's points.

Therefore,

You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. Rise divided by Run gives you the slope. Run = rise + slope Rise + run = slope.

Step-by-step explanation: Part 1) The units rates are

A)

B)

C)

D)

Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume

Part 1) Calculate the unit rate for each size

case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction

Find the unit rate

case B) we have

18 2/2 oz. bottle costs $1.49

Convert mixed number

Find the unit rate

case C) we have

48 1/4 oz. carton costs $2.49

Convert mixed number to an improper fraction

Find the unit rate

case D) we have

64 3/4 oz. carton costs $3.75

Convert mixed number to an improper fraction

Find the unit rate

Part 2) which size is the best buy

we know that

The best buy is the one with the smallest unit rate

so

The best buy is the size 48 1/4 oz

Answer:

Price of each ticket = $70

The revenue generated from sales of 10 tickets = 70 x 10 = $700

After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500

Net Profit = Revenue - Cost

Revenue from n tickets will be = 70n

Cost = $1500

So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

Answer:

Abigail walks more steps than Mary.

To find out who many steps each one of them walks in a week, we have to carry out different calculations starting with Abigail.

                Calculation for number of steps taken by Abigail

Abigail takes 6000 steps in 50 minutes. We can use this information to scale up his number of steps over a period of 5 hours(300 minutes.). The quickest way to do this calculation, is to notice that there are 6 different 50 minute segments in 300 minutes. This means that the number of steps taken in 5 hours is  steps.

Another way to do this calculations is to use proportions

.

Abigail takes 36000 steps that week.

                Calculation for number of steps taken by Mary

The number of steps taken by Mary is given by the is given by the function  where  is the time in minutes. Mary walks for a total of 5 hours or 300 minutes. We calculate the number of steps she takes as shown below,

Mary takes a total of 35400 steps.

Since  36000 steps is greater than 35400 steps, we conclude that Abigail walks more steps than Mary.

Answer:

y = -2x + 16

Step-by-step explanation:

[tex]Slope:\frac{y^{2}-y^{1} }{x^{2}-x^{1} }=\frac{12-2}{2-7}=\frac{10}{-5}=-2[/tex]

[tex]y-intercept:y-y_{1}=m(x-x_{1} ) \\y-2=-2(x-7)\\y-2=-2x+14\\[/tex]

Add 2 to both sides;

y = -2x + 16

Answer and Step-by-step explanation:

When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:

[tex]a^{x} * a^{y} = a^{x+y}[/tex]

When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:

[tex]a^{x} / a^{y} = a^{x-y}[/tex]

When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:

[tex](a^{x)^{y} } = a^{xy}[/tex]

When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:

[tex](ab)^{x} = a^{x} b^{x}[/tex]

He took a rest from driving at 4pm. That is proved through there being no change in the number of miles from 4pm to 5pm.

He covered 50 miles from 1pm-2pm and 3pm-4pm. 175-125=50 and 250-200=50.

I am not sure about the answer to part c but it is not iii, so it is either i or ii.

I also do not believe it is i because you can calculate his speed from the given information on the graph so if I were you I would circle ii.
