Answer:

-4

Step-by-step explanation:

Hey there!

Well the slopes of 2 parallel lines have the same slope,

meaning if the green line has a slope of -4 then the slope of the red line has a slope of -4.

Hope this helps :)

find the slope of the line on the graph write your answer as a fraction or a whole number not a mixed number or decimal

Alexandra [31]

The slope is (4,3). You look at the y intercept (where the y axis is crossed by the line) and simply count rise over run until you reach the next point. The next point from the y intercept (-2,0) is (2,3).

-2+4=2
0+3=3

And there you go. In fraction form it’s 4/3.
Hope this helped!

Look at this sequence of numbers: 0, 1, 2, 4, 6, 9, 12, 16, ? - what number should replace the question mark?

andreev551 [17]

Answer:

Step-by-step explanation:

0 to 1 = a difference of 1

1 to 2 = a difference of 2-1 = 1

===============

2 to 4 = a difference of 2

4 to 6 = a difference of 2

===============

6 to 9 = a difference of 3

9 to 12 = a difference of 3

===============

12 to 16 = a difference of 4

16 to 20 = a difference of 4

An airplane travels 600 miles against the wind in 4 hours, and makes the return trip with then same wind in 2 hours. Find the sp

SOVA2 [1]

Answer:

The speed of wind is 75 miles / hour

Step-by-step explanation:

Let's assume

speed of airplane is x miles /hour

speed of wind is y miles /hour

Against wind:

An airplane travels 600 miles against the wind in 4 hours

against wind means resultant speed will be less

so, speed =x-y

total distance traveled in 4 hour is

$=4(x-y)$

and this has to be equal to 600

$600=4(x-y)$

Divide both sides by 4

and we get

$x-y=150$

With wind:

makes the return trip with then same wind in 2 hours

with wind means resultant speed will be more

so, speed =x+y

total distance traveled in 2 hour is

$=2(x+y)$

and this has to be equal to 600

$600=2(x+y)$

Divide both sides by 2

and we get

$x+y=300$

So, we get system of equations

$x-y=150$

$x+y=300$

now, we can solve it by adding both equations

$x-y+x+y=150+300$

$2x=450$

now, we can solve for x

$x=225$

now, we can find y by plugging x into any one equation

$225+y=300$

$y=75$

So,

The speed of wind is 75 miles / hour

Question 1 Convert the mixed number to an improper fraction.

Mashcka [7]

Step-by-step explanation:

to convert a mixed number to an improper fraction: take the big whole new on the right and multiply it by the denominators or number on the bottom of the fraction. then add thay amount to the numerator, or number on top and leave the denominator as it was before

example: 2 3/5 = 13/5

you can dissect the example to figure out the formula (formula is the way to solve an equation)
