Start by finding the slope.

Pick 2 points on the line and find the “rise” and “run” between them.

To get from (0,3) to (4,0), you’d need to go “down 3” and “right 4”.

Since the slope is “rise over run” and a rise of “down 3” means a rise of “-3”, your slope is -3/4.

Next find the y-intercept: (0,3)
Use the 3 as your b-value for the slope-intercept form.

y=mx+b becomes y= -3/4 x + 3

hoa [83]
<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>

So right now i'm doing "solving Inequalities" i need help with this question<br> 3v-12&gt;5v+10
LenKa [72]

Answer:

v < -11

Step-by-step explanation:

  1. Combine like terms: 3v - 5v > 12 + 10
  2. Simplify: -2v > 22
  3. Divide each side by -2 to cancel out the -2 next to v. It should now look like this: v < -11

I hope this helps!

A group of friends wants to go to the amusement
Zepler [3.9K]

Answer:

The maximum amount of people that can go to the amusement park is 15.

Step-by-step explanation:

First you create an equation to represent the question

8.75+25.75x≤420

You put the less than or equal to sign because 420 is the maximum amount of money.

Now you just solve the equation.

25.75x≤420-8.75

25.75x≤411.25

x≤411.25/25.75

x≤15.9708738

Then you have to round down because you cant have .9 of a person.

So x≤15

Then, Check your solution

8.75+(25.75 x 15)≤420

8.75+386.25≤420

395≤420

That is true. But to make sure that is the maximum add another 25.75

395+25.75≤420

420.75≤420

This is equation is false so, our answer is correct.

The maximum amount of people that can go to the amusement park is 15.
