Five years ago, Jay borrowed $1500 from his mother. He agreed to pay $150 in interest. What is the simple annual interest rate for this loan?

The equation of the line parallel to the line y = -7x + 2 will be -

y = - 7x - 3.

Given is the equation of line as y = -7x + 2.

        y = mx + c

The equation of line parallel to the given line will be of the form -

y = - 7x + c                                               {parallel lines have same slope}

For the point (- 5, 32), we can write -

32 = - 7 x - 5 + c

c = 32 - 35

c = - 3                                                       {y - intercept}

The equation of the line will be -

y = - 7x - 3

Therefore, the equation of the line parallel to the line y = - 7x + 2 will be -

y = - 7x - 3.

Answer:

The volunteers donated  [tex](15040-470n)[/tex] milliliters of blood.

Step-by-step explanation:

Total number of volunteers was 32 and the number of volunteers couldn't donate blood was [tex]n[/tex].

So, the number of remaining volunteers who donated blood will be: [tex](32-n)[/tex]

Each of these volunteers donated 470 milliliters blood.

So, the total amount of blood donated [tex]= 470(32-n) = (15040-470n)[/tex] milliliters.

Answer:

Answer: The answer to this problem would be (32-n)*470!

Step-by-step explanation:

Since there were 32 volunteers the beginning and some of them couldn't donate you would subtract (the variable you would use is 'n'). As you may know, each means that you multiply so if each volunteer is giving 470 mm of blood each you would multiply that by how many volunteers are remaining which is unknown.

Your final answer would be: (32-n)*470

Answer:

The artist's earnings for the CD will be $168000.

Step-by-step explanation:

The total sales amount is $2500000

The artist receives a royalty payment of 7%. So, the amount of royalty, the artist receives will be:  [tex](\$2500000\times 7\%)= (\$2500000\times 0.07)=\$175000[/tex]

The agent gets 4% of what the recording artist gets. So, the amount of money the agent gets will be:  [tex](\$175000\times 4\%)=(\$175000\times 0.04)=\$7000[/tex]

So, the artist’s earnings for the CD will be:  [tex](\$175000-\$7000)= \$168000[/tex]

Speed = Distance /  time:

Speed = 825 miles / 17 hours

Speed = 48.529 miles per hour. (Round the answer as needed).

Gas mileage = miles traveled  / gallons used

Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).

Unit rate of gas = Total money spend /  gallons bought:

Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.

Answer:

[tex]Speed = 48.53mph[/tex]

[tex]Gas.Mileage = 27.7 mpg[/tex]

[tex]Unit.Price = 3.29/gallon[/tex]

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

In order to find the Speed we need to divide the amount of total miles in the trip to California by the amount of time that it took.

[tex]Speed = \frac{Miles}{Hours}[/tex]

[tex]Speed = \frac{825.miles}{17.hours}[/tex]

[tex]Speed = 48.53mph[/tex]

Next we can calculate the Gas Mileage by dividing the amount of total miles  by the amount of gallons of gas that the trip wasted.

[tex]Gas.Mileage = \frac{Miles}{Gallon}[/tex]

[tex]Gas.Mileage = \frac{825.miles}{38.gallons}[/tex]

[tex]Gas.Mileage = 27.7 mpg[/tex]

Finally, we can calculate the Unit Price by dividing the total amount of money wasted in the trip by the amount of gallons used in that trip.

[tex]Unit.Price = \frac{Total}{Gallons}[/tex]

[tex]Unit.Price = \frac{125}{38.gallons}[/tex]

[tex]Unit.Price = 3.29/gallon[/tex]

Answer: The answer is (C). [tex]y\geq 0.[/tex]

Step-by-step explanation:  We are given a graph in the figure and we are to identify the range of the graphed function from the given options.

We can see in the figure that the values of x are greater than or equal to 0 and the corresponding values of y are also greater then or equal to 0. Since we are talking about the range of the function, so we will consider the y-values.

Thus, the range of the function will be [tex]y\geq 0.[/tex]

Thus, (C) is the correct option.

Answer:

The overall change in temperature over the time period ∆T = -12.6°F

Hope This Helps :DD

Step-by-step explanation:

(a)

Let's assume

y is total cost

x is number of ride tickets

(b)

Since, this is linear relationship

so, we can assume equation as

[tex]y=mx+b[/tex]

The Fall Festival charges $0.75 per ticket for the rides

so,

[tex]m=0.75[/tex]

we can plug it

[tex]y=0.75x+b[/tex]

Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

so, we have

at x=18 , y=33.50

we can use it to find b

[tex]33.5=0.75*18+b[/tex]

now, we can solve for b

[tex]b=20[/tex]

we can plug it back

and we get

[tex]y=0.75x+20[/tex]

(c)

we got

[tex]y=0.75x+20[/tex]

here ,

y is the cost for anyone who only pays for festival admission and rides

x is number of admission

so, our equation will give total cost

Here are some examples 3/3, 4/4, 5/5, 1/1, 2/2, 6/6. It's any number over it self.

Okay for this problem you can multiply 6 by 4.5 aand get 27 as your answer.

So 6×4.5=27 miles in 4.5 hours

We need to graph a function and use that graph to estimate how many miles lava moves in 4.5 hours.

The graph and estimations can be seen at the end of the answer.

Let's see how to graph this:

We know that the function is y= 6*x

What we need to do, is find two points in the that belong to the line, to get that, we need to evaluate the function in two points:

if x = 0:

y = 6*0 = 0

Then we have the point (0, 0)

if x = 1:

y = 6*1 = 6

Then we have the point (1, 6)

Now to graph the function, we just need to find these two points and draw a line that connects them.

A graph is shown at the end of the answer.

To estimate the distance that the lava has moved in 4.5 hours, we need to find the value 4.5 in the x-axis, then we draw a vertical line that passes through there.

In the point where this vertical line intersects the graph, we draw a horizontal line.

That horizontal line will intersect the y-axis in the correspondent y-value to x = 4.5

An example of this can be seen in the image below, my estimation is that the lava has moved something near 26 miles.

20x

in mathematics ' product ' means multiply

4 × 5x = 20x

Answer:

You can conclude that the lines are perpendicular, and will cross at exactly one point.

Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.

The slope of a line illustrates the direction of the line

The two lines are perpendicular lines

From the question, we understand that:

As a general rule,

A vertical line and a horizontal line will meet at a right-angle

Hence, the conclusion about the two lines is that, the two lines are perpendicular lines
