madreJ [45]

Answer:

Fast train speed: 69 km/h

Slow train speed: 39 km/h

Step-by-step explanation:

Fast train:

-Time: 4.33

-Speed: x

-Distance: 4.33x

Slow train:

-Time: 7.66

-Speed: x - 30

-Distance: 7.66(x - 30)

7.66(x - 30) = 4.33x

7.66x - 229.8 = 4.33x

3.33x = 229.8

x = 69

Consider the equation y = -2x + 5. Create a table of five ordered pairs that satisfy the equation. What is the y-intercept of th

Tatiana [17]

Answer: option d.

Step-by-step explanation:

To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":

For $x=-2$

$y = -2(-2) + 5=9$

For $x=-1$

$y = -2(-1) + 5=7$

For $x=0$

$y = -2(0) + 5=5$

For $x=1$

$y = -2(1) + 5=3$

For $x=2$

$y = -2(2) + 5=1$

Then, you can make the table:

<em><u>x</u></em><u> </u><u>-2 -1 0 1 2</u>

<em><u>y </u></em><u> </u><u>9 7 5 3 1</u>

To find the x-intercept, substitute $y=0$ into the function and solve for "x". Then:

$0 = -2x + 5\\\\x=\frac{-5}{-2}\\\\x=\frac{5}2}$

This is: ( $\frac{5}{2}$ , 0)

To find the y-intercept, substitute $x=0$ into the function and solve for "y". Then:

$y= -2(0) + 5\\\\y=5$

This is: (0,5)

suppose you have a rectangle with a length 8 cm and width 3 cm. Now suppose the sides are doubled. Find the percent os increase

mr Goodwill [35]

The original perimeter is 22 cm.

If both sides are doubled, the length would be 16 cm and the width would be 6 cm.
The perimeter would be 44 cm.

22/44 is 50%.
