Answer:

third option listed

Step-by-step explanation:

We know that Johnny does not ever stay/wait at the same distance from the wall, as that would look like a flat line (the y-value / distance would be unchanging, it would be constant)

So, the only possibly correct option is C, because all other options describe him pausing

But why is it not A? We know that at "0" y we are at the gym wall, and that each point is a point that he turns around and runs the opposite way. He first runs away, back, away, back, away, back--which we know because of the direction of the line over time. We also can tell that each period of "away, back" is the same distance, and it takes the same time to travel that distance, by looking at the length of each line.

hope this helps!! have a lovely day :)

Answer:

the 3rd answer option

Step-by-step explanation:

as we can see, time is on the x-axis.

(0, 0) means start of the action (0 seconds) with 0 distance to the gym wall.

then we see that for 2 seconds Johnny increases the distance to the gym wall up to 3 units (the line goes to (2, 3)).

then we see that for the next 2 seconds he returns to the gym wall (0 distance).

then for 3 seconds he increases the distance to the gym wall to 5 units. the line goes to (7, 5). and then for the next 3 seconds he returns to the gym wall (0 distance). then for 4 seconds he increases the distance to the gym wall to 7 units. the line goes to (14, 7). abd then for the next 4 seconds he returns to the gym wall (0 distance).

The mean of the scores if 6 students in a competitive exam is 25 marks.

Given scores of 6 students are: 10,30,50,40,20 in a competitive exam.

We have to find out the mean of the mark of 6 students in a competitive exam.

Mean is the sum of all the values in a set of data, such as numbers, measurements, divided by the number of values. It is also known as average.

Mean=∑X/n

∑X=10+30+50+40+20

=150

N=6

Now to calculate the mean we have to divide 150 by number of students which is 6.

Mean=150/6

=25 marks.

Hence the mean of the scores of 6  students is 25 marks.

So he needs to sell $2,000 in merchandise.

We can assume that we have a proportional relation:

y = k*x

Where y is the commission and x is what Norman sells, then:

$15 = k*$200

k = $200/$15 = 0.075

$37.50 = k*$500

k = $500/$37.50 = 0.075

Then the relation is:

y = 0.075*x

If he wants a commission of $150, then:

$150 = 0.075*x

$150/0.075 = x = $2,000

So he needs to sell $2,000 in merchandise.

The plane reaches its destination at 12h10 minutes if the plane leaves town A for town B.at 0540hours

For legal, commercial, and social purposes, a time zone is a region that observes a uniform standard time. Instead of strictly following longitude, time zones tend to follow the borders between countries and their subdivisions.

We have:

A plane leaves town A for town B.at 0540hours.If the journey takes 6.5hours

We can write the ordered pairs that meet this condition as:

(x, y) = (x, (9 + x)/4 )

An ordered pair on the X-Y plane is written as (x, y).

Here we also have the relation:

-x + 4y = 9

If we isolate y, we get:

4y = 9 + x

y = (9 + x)/4

Now, we can write the ordered pairs that meet this condition as:

(x, y) = (x, (9 + x)/4 )

To get the particular ones you can replace the value of x, for example, if x = 0, then:

Bank: Wells Fargo is a commercial bank that provides services for individuals, small businesses, and corporations. The bank manages IRAs (traditional and Roth), which are retirement funds that invest in different stocks and bonds to earn interest. Traditional IRAs offer tax-deferred growth. An individual doesn't have to pay taxes on earnings until he or she is ready to make withdrawals (i.e., after retirement). Roth IRAs offer tax-deferred growth until retirement and tax-free withdrawals while in retirement. The bank offers merchant services for small businesses. The bank processes payments via credit cards, debit cards, checks, gift cards, and international payments. Wells Fargo also gives small businesses options on how to accept customer payments: online shopping carts, mobile apps, and onsite payment processing equipment.The bank offers affordable student loans to cover the cost of tuition, books, computers, and housing. Students are not required to make loan payments until six months after leaving school. The bank offers two types of interest rates on student loans: variable and fixed. Variable interest rates range from 3% to 8% and fixed rates range from 5% to 10%.

Credit union: Navy Federal Credit Union has more than 5 million members. It is available for anyone who is affiliated with the Armed Forces, Coast Guard, National Guard, or the Department of Defense, or anyone who has a family member who is already a Navy Federal member. It offers a fixed-rate home equity loan for members. Home equity loans use a borrower’s home as collateral for the loan. These loans are usually used to pay for major expenses such as home repairs, college education, medical bills, and so on. The borrower can borrow up to 100 percent of the home's property value, with the agreement that the fixed-rate loan will be paid off in 20 years (longest term available). This credit union guarantees no hidden closing costs on the loan. It offers motorcycle, boat, and leisure vehicle loans. The loans require zero down payment and promise to cover the cost of the vehicle/boat, taxes, title, and tags. This is a good loan for someone who has not saved any money prior to choosing to buy a vehicle.It also offers prepaid Visa cards, which are useful for students and young adults who are learning to control expenses. Unlike most prepaid cards, this credit union states there are no hidden monthly fees, activation charges, or purchase fees. The prepaid cards can be loaded up to $10,000 and are protected by the credit union's zero liability policy. There are spending limits associated with the program: an ATM withdrawal limit per day of $600 and a spending limit of $3,000 per day.

The number of days Tayloe will take to travel 100 miles if he travels 35 miles every 2 days is 40/7 or 5 5/7 in fraction form.

A fraction is a representation of a part of the whole.

Written as a/b, read as "a by b", it functions as a number of parts of a total of b number of parts.

In the question, we are given that Tayloe travels 35 miles every 2 days to work.

Therefore, daily traveling done by Tayloe can be shown as a fraction, 35/2 miles.

The total traveling given to us is 100 miles.

Thus, the number of days Tayloe will take to travel 100 miles can be shown in fractional form as 100/(35/2) = (100*2)/35 = 40/7 or 5 5/7.

Answer:

the second option: [tex]7x+4y=44[/tex]

Step-by-step explanation:

So when a line is parallel, it means that it has the same slope and a different y-intercept, it's important that there is a different y-intercept, otherwise it would be the same line, and the "two lines" would intersect at infinite points.

Anyways by looking at the graph you have two points (-8, 5) and (-4, -2). So the run in this case was 4 and the rise was -7. This is a slope of -7/4. So we have the equation: [tex]y=-\frac{7}{4}x+b \text{ where b}\ne-9}[/tex]. Since it passes through the point (8, -3) we can plug that in as (x, y) to solve for b (the y-intercept)

Plug in (8, -3) as (x, y)

[tex]-3=-\frac{7}{4}(8)+b[/tex]

Multiply the -7/4 and 8

[tex]-3 = -14+b[/tex]

add 4 to both sides

[tex]11 = b[/tex]

So this gives us the equation:

[tex]y=-\frac{7}{4}x+11[/tex]

Since it's asking for it in standard form you move the 7/4 x to the other side

Add 7/4x to both sides

[tex]\frac{7}{4}x+y=11[/tex]

Multiply both sides by 4 to cancel out the fraction

[tex]7x+4y=44[/tex]

P(1) = P(-1)

P(1) = 3 - a + b
P(-1) = -3 + a + b

-> 3 - a + b = -3 + a + b
-> 3 - a + b + 3 - a - b = 0
-> 6 - 2a = 0
-> a = 3.

P(2) = 24 - 2a + b -> 24 - (2a - b) = 16 -> 2a - b = 8
-> 6 - b = 8
b = -2.

So, a = 3 and b = -2

Recheck : P(1) = 3 - 3 + (-2) = -2
P(-1) = -3 + 3 + (-2) = -2 => P(1) = P(-1) (true)

P(2) = 24 - 6 + (-2) = 16.

From the markings on the diagram, we can tell E is the midpoint of BC and D is the midpoint of AC. We can apply the triangle midsegment theorem: ED = ½BA. Substituting in the expressions for the lengths and solving for x, we get x = 5. Now, since BE = x, then BC = 10.

Triangle midpoint theorem states that the line segment which joins the midpoints of two (2) sides of a triangle is parallel to the third side, and it's congruent to one-half of the third side.

By applying the triangle midpoint theorem, we can find the value of x:

ED = ½BA

x + 2 = ½(4x - 6)

2x + 4 = 4x - 6

4x - 2x = 6 + 4

2x = 10

x = 10/2

x = 5.

BC = x + x

BC = 5 + 5
