Please help me on question 4 and 5 I am really stuck thank you I would really appreciate it
STALIN [3.7K]

Answer:

1. 5/4

2. 7

Step-by-step explanation:

1) Lets call the width as w

Therefore length would be:

w+4

To find the perimeter you use the formula:

2 (l+w)

Now substitute our values into this formula:

2 (w+4+w)

2( 2w+4)

4w+8

Now make this equal to 13:

4w +8 = 13

4w = 5

w = 5/4

2. In this question we will call length l

Therefore width would be:

l-5

Now we will do the steps we did above:

2 (l+l-5)

2 (2l-5)

4l -10

4l - 10 = 18

4l = 28

l = 7

Determine the equation of the line with slope 3 that passes through the point (2, 0).
Aleonysh [2.5K]

Hello there! :)

If we are given the slope of the line and a point that the line passes through, we can write its equation in point-slope form:

y-y1=m(x-x1)

y-0=3(x-2)

y-0=3x-6

y=3x-6

Therefore, that's the equation. The right option is Option C.

I hope this helps you.

Please let me know if you have any doubts.

Good luck on your assignment.
