Replace x with any number and solve for Y.

Do this at least twice to get 2 points.

Place these points on the graph and draw a line through them.

See attached graph.

Let x = 2

y = 1.4(2)

y = 2.8

First point = (2,2.8)

Let x = 5

y = 1.4(5)

y = 7

Second point = (5,7)

The y-intercept is zero, that means the line is passing through origin.

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

The equation is given below.

y = 1.4x

In the above equation, y-intercept is not there, which means the line is passing through origin.

The given number 11.69517 rounded to the nearest thousandth is 11.695.

What is the rounding off the number?

Rounding off a number means approximating it to a certain degree of accuracy by replacing it with another number that is nearly equal to it but has a shorter, simpler, or more explicit representation.

To round 11.69517 to the nearest thousandth, we look at the digit in the fourth decimal place, which is 5. Since 5 is greater than or equal to 5, we round up the digit in the third decimal place (9) by adding 1 to it. Therefore, 11.69517 rounded to the nearest thousandth is 11.695.

Hence, the given number 11.69517 rounded to the nearest thousandth is 11.695.

Answer: 8

Step-by-step explanation:

Answer:

I dont know what your supposed to do but i can tell you that x = 5 because if you simplify the equation you get 3x + 5 = 4x. Using this you can infer that a single x is equivalent to 5 since you need 5 to get from 3x to 4x.

It will take 2.6 hours (or 2 hours and 36 minutes) long for the two trains to meet when Two trains leave stations 520 miles apart at the same time and travel toward each other.

To find the time it will take for the two trains to meet, we can use the concept of relative speed.

The two trains are traveling towards each other, so their speeds add up. The combined speed of the two trains is:

110 mph + 90 mph = 200 mph

To determine the time it will take for the trains to meet, we can divide the total distance they need to cover (520 miles) by their combined speed (200 mph):

Time = Distance / Speed

Time = 520 miles / 200 mph

Time = 2.6 hours

Therefore, it will take 2.6 hours (or 2 hours and 36 minutes) for the two trains to meet.

Answer:

Step-by-step explanation:

This one is simple substitution... at least, substitution is the easiest method. The first equation is 3x – 30 = y  and the second is 7y – 6 = 3x

As I look, I see 3 ways to use substitution to solve this:

We're going to only use 1 method for the sake of time. Try the other two on your own. Assuming you don't make any mistakes, they will work.

Method 1:

3x – 30 = y

7y – 6 = 3x  — initial system of equations

7y – 6 – 30 = y  — substitute 7y – 6 for 3x

7y – 6 – 30 = y  — marking like terms, bold for constants, underlined for variables

7y – 36 = y  — combining the constants and simplifying

Here, you could diverge into multiple paths: add 36 to both sides, subtract y from both sides, divide by 6 OR subtract 7y from both sides and divide by –6 . For the sake of time, I'm subtracting 7y, though I don't like dealing with negatives.

7y – 7y – 36 = y – 7y  — subtract 7y from both sides

–36 = –6y  — simplify

–36 ÷ –6 = –6y ÷ –6  — divide by –6 on both sides

y = 6  — simplify

Again, we can diverge here: substitute y into 3x – 30 = y or substitute y into 7y – 6 = 3x

I'm going to choose 3x – 30 = y but it will work either way, should you take the time (if you have it) to chase down every path this problem can take.

3x – 30 = y  — initial equation

3x – 30 = 6  — substitute 6 for y

3x – 30 + 30 = 6 + 30  — add 30 to both sides to isolate 3x

3x = 36  — simplify the expression

3x ÷ 3 = 36 ÷ 3  — divide both sides by 3 to isolate x

x = 12  — simplify

So, we have x = 12 and y = 6 . We know they work for 3x – 30 = y  but not if they work for 7y – 6 = 3x . Let's substitute those in to see if (12, 6) really is the solution point.

7y – 6 = 3x  — original equation

7(6) – 6 ≟ 3(12)  — substitute 6 for y and 12 for x

42 – 6 ≟ 36  — simplify by multiplying

36 = 36 ✔  — simplify by combining like terms on left side

Success! It works! We have found our solution!

I hope this helps increase your understanding of the concept. Have a great day!

Answer:

x = 4

y = 6

Step-by-step explanation:

3x + 4y = 36

3x + 4(-1/2x + 8) = 36

3x - 2x + 32 = 36

x + 32 = 36

x + 32 - 32 = 36 - 32

x = 4

y = -1/2x + 8

y = -1/2(4) + 8

y = -2 + 8

y = 6

Answer:

The shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]

Step-by-step explanation:

The shaded area is equal to the area of the outer circle minus the area of the inner circle.

The area of the outer circle is equal to [tex]r^2\pi = 50^2\pi = 2500\pi[/tex] feet.

The area of the inner circle is equal to [tex]r^2\pi = 36^2\pi = 1296\pi[/tex] feet.

So the area of the shaded area is equal to [tex]2500\pi - 1296\pi = 1204\pi.[/tex]
