HELP PLEASE I GIVE BRAINLIEST

Mathematics
1 answer:
marta [7]3 years ago
5 0

Answer:

30

Step-by-step explanation:

Perimeter of rectangle = 5y - 1 + 4y + 2 + 5y - 1 + 4y + 2

                                      = 18y + 2

18y + 2 = 128

18y = 128 - 2

     = 126

y = 126 ÷ 18

y = 7

Length of AD = 4y + 2

                      = 4(7) + 2

                      = 28 + 2

                      = 30

Write the equation of a line that passes<br> through (-3,-8) and (3, 10).
Xelga [282]

Answer:

y=3x+1

Step-by-step explanation:

The equation will most likely be in slope-intercept form which is

y=mx+b

(m) is the slope,

(b) is the y intercept

First we must find the slope. The formula for slope is (y1-y2)/(x1-x2)

Which means we take the (y) of the second given point and subtract the (y) if the first given point, then divide that by the (x) of the second given point minus the (x) of the first given point.

(10-(-8)/3-(-3)

18/6

Simplify

3/1

3, our slope is 3.

Now we can put this into our formula

y=3x+b

To find the y intercept we just apply one of the given points. (I'll use (3, 10) but either of them would work.

10=3(3)+b

Now solve

10=9+b

Subtract 9 from each side

1=b

Now we put our slope and y intercept into our formula

y=3x+1.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Mrs. Cho has 24 students in her class. Some of her students are also in the play. Explain why it is not possible for exactly 24%
lora16 [44]
Let's start by calculating how many students does 24% represent.
24% * 24 = 0.24 * 24 = 5.76
We got a decimal number as solution. The reason why exactly 24% students can't be in the play is because this percentage does not represent whole number of students. She can't take 0.76 students

If she wanted 25% students to be in a play it would mean she has to take:
25% * 24 = 0.25 *24 = 6 students
