Easy a) -2,-5.-8.-11,...

Draw to show how you can use models to compare a 345 and 391

natali 33 [55]

345= 3 hundreds, 4 tens, and 5 ones
391= 3 hundreds, 9 tens, and 1 one
You can use the model I attached to help u see it better.
Hope this helps!

A case of Mountain Dew (24cans) costs $7.68. What is the unit price?

Ronch [10]

Here are the unit rates involved:

$7.68 / 1 case = $7.68 per case

$7.68 / 24 cans = $0.32 per can

1 case / $7.68 = 0.13 case per $

24 cans / $7.68 = 3.125 cans per $

And of course ...

24 cans / 1 case = 24 cans per case

1 case / 24 cans = 0.041666... case per can

Write the equations for the line parallel and the line perpendicular to the given line passing through the given point.

pashok25 [27]

Answer:

10. y=2x+1 y = -1/2x +1

11. y=-1/3x +6 y = 3x -4

12. y=-5x-18 y=1/5x + 14/5

Step-by-step explanation:

To write the equation of a line we must have a slope and a point. To find the slope, we use the slope from the equations for parallel lines and modify it for perpendicular lines.

10. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is 2. The parallel slope is 2 and the perpendicular slope is the negative reciprocal or -1/2.

Parallel Perpendicular

(y-1)=2(x-0) (y-1)==-1/2(x-0)

y-1=2x y-1 = -1/2 x

y=2x+1 y = -1/2x +1

11. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is -1/3. The parallel slope is -1/3 and the perpendicular slope is the negative reciprocal or 3.

Parallel Perpendicular

(y-5)=-1/3(x-3) (y-5)=3(x-3)

y-5=-1/3x+1 y-5 = 3x - 9

y=-1/3x +6 y = 3x -4

12. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form. The slope here is -5. The parallel slope is -5 and the perpendicular slope is the negative reciprocal or 1/5.

Parallel Perpendicular

(y-2)=-5(x--4) (y-2)=1/5(x--4)

y-2=-5(x+4) y-2 = 1/5(x +4)

y-2=-5x -20 y-2 = 1/5x +4/5

y=-5x-18 y=1/5x + 14/5
