Margo drove for 3.85 at an average speed of 61.4. Estimate the total distance that she drove.

makkiz [27]

About 245.6 miles. This is because 3.85 is about 4 hours and that times 61.4 is 245.6miles

In the figure, Blueline is Line AB and Redline is target line.

You can see that the target line does not pass through (18,-8)

Step-by-step explanation:

In the figure, Blueline is Line AB and Redline is target line.

You can see that the target line does not pass through (18,-8)

Taking a bottom-left corner of the graph as (0,0)

Given Line AB,

Point A is located as (4,9)

Point B is located as (16,1)

The slope of AB is

$=\frac{Y1-Y2}{X1-X2}$

$=\frac{9-1}{4-16}$

$=\frac{8}{-12}$

$=\frac{-2}{3}$

The question says " Draw a line passes through C(13,12) and parallel to Line AB "

Now, Let the equation of the target line is y=mx + c

Where m=slope and c is the y-intercept

The target line is parallel to the line AB

The slope of the Target line = The slope of the Line AB $=\frac{-2}{3}$

m= $=\frac{-2}{3}$

We can write, the equation of the target line is

$y=\frac{-2}{3}x + c$

Also, the Target line is passing through C(13,12)

Point C satisfies the equation

$y=\frac{-2}{3}x + c$

$12=\frac{-2}{3}13 + c$

$12=\frac{-26}{3} + c$

$12+\frac{26}{3}=c$

$c= 12+\frac{26}{3}$

$c= \frac{62}{3}$

Replacing the value

the equation of the target line is

$y=\frac{-2}{3}x + c$

$y=\frac{-2}{3}x + \frac{62}{3}$

$3y= -2x + 62$

It is also asked that if a line is extended , would it passes through the (18,-8)?

If a line passes through the point (18-,8) then, that point must satisfy the equation of a line

the equation of the target line is $3y= -2x + 62$

$3(-8)= -2(18) + 62$

$(-24)= (-36) + 62$

$(-24)= 26$

Left land side is not equal to right hand side.

Therefore. a line does not pass through the point (18,-8)

The sum of four consecutive integers is 390. Find the integers (Please show your work)

AysviL [449]

Step-by-step explanation:

The sum of three consecutive even integers is 390. What are the integers?

In order to ensure the numbers are even I generally call the first

integer 2n because 2 multiplied by any number will always be even.

Our consecutive even integers are: 2n, 2n+2, 2n+4

2n + 2n+2 + 2n+4 = 390

6n + 6 = 390

6n = 384

n = 64

Our 1st integer is 2n = 2(64) = 128

Our integers are 128, 130, 132

Check: 128+130+132 = 390 which is correct.

2) The sum of three consecutive odd integers is 99. What are the integers?

Same logic applies: An odd integer will always result from 2n+1

So we will call our 3 consecutive odd integers 2n+1, 2n+3, 2n+5

2n+1 + 2n+3 + 2n+5 = 99

6n+9 = 99

6n = 90

n = 15

Our first odd integer is 2n+1 = 2(15) + 1 = 31

Our 3 consecutive odd integers are 31, 33, 35

Check: 31 +33+45 = 99 Yes

3)Which equation defines three consecutive odd integers that add up to 81?

A) n(n+1)(n+2)=81

B) n(n+2)(n+4)=81

C) n+(n+1)+(n+3)=81

D) n+(n+1)+(n+2)=81

E) n+(n+2)+(n+4)=81

We can immediately discard answers A, B because they are multiplying

instead of adding.

That leaves C, D, E

This question does not follow the logic I utilized in question 1 and 2.

Assuming the first number is indeed odd and is called n

The next odd number is n+2 followed by n+4

Thus we must have: n + (n+2) + (n+4) = 81

The answer is E

By the way: The numbers are 25, 27, 29
