Answer:

y = -3x -2 ( this is only for 5 )  

Step-by-step explanation:

Step 1:

First, we need to understand that lines that are perpendicular have slopes that are opposites and reciprocals of each other.

Step 2:

So our initial equation is 2x-6y= 10. We want to rearrange this so that it is in slope-intercept form: y= 1/3x -(10/6). In this form, we can derive the slope of our new line. Because the slope is 1/3, our new slope is -3 ( based on step 1 ).

Step 3:

Now that we have the slope of our new line, we can use the point-slope formula to get our specific line that passes through ( 2, -8 ).

y - y1 = m( x - x1 )

y- ( -8 ) = -3( x - 2 )jhvjjfjhjfhcgch

y + 8 = -3x + 6

y = -3x -2 !

If Roger were 32 years older, he would be three times as old as he is now. How old is<br> Roger?
stellarik [79]

Answer:

16

Step-by-step explanation:

Set up the equation ->

x+32=3x  

(you can get this easily by writing the equation down as you read the problem)

--> revisiting  x+32=3x

-x on both sides to isolate the number and put the like terms together

We are left with  32=2x

Divide 2 on both sides, and you will get x (his current age) --> x=16

Roger is currently 16 years old.

Jack and Jim went biking. Jack biked for 5 1/3 hours with average speed 12 1/2 miles per hour. Jim traveled exactly 1 1/5 as far
ahrayia [7]
Given that Jack biked for 5 \frac{1}{3} hours with an average speed of  12 \frac{1}{2} miles per hour.

The distance travelled by Jack is given by

d=speed\times time \\  \\ =12 \frac{1}{2}\times5 \frac{1}{3}= \frac{25}{2} \times \frac{16}{3}  \\  \\ = \frac{200}{3} =66 \frac{2}{3} \ miles

Given that Jim travelled exactly 1 \frac{1}{5} as far as Jack did, then the distance Jim travelled is given by

d=1 \frac{1}{5} \times66 \frac{2}{3}  \\  \\ = \frac{6}{5} \times \frac{200}{3} =80

Therefore, the length of Jim's journey is 80 miles.

Tony is at a car rental service to rent a car. There is an administration fee of $50 to rent a car and then it costs $20 for eac
Nookie1986 [14]

Answer:

20x+50

Step-by-step explanation:

Let x represent the number of days he has the car

20x+50

It is 20x, because it costs 20 dollars for each day he has the car, and +50, because there is a fee, regardless of how many days he has the car.

Hope this helps!
