Answer:
3000 students
Step-by-step explanation:
If 48% of the students are female, and there are 1440 female students, we can set up a percentage proportion, assuming x is the total amount of students.
![\frac{1440}{x} = \frac{48}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1440%7D%7Bx%7D%20%3D%20%5Cfrac%7B48%7D%7B100%7D)
We can use the cross products property to find the value of x.
![1440\cdot100=144000\\\\144000\div48=3000](https://tex.z-dn.net/?f=1440%5Ccdot100%3D144000%5C%5C%5C%5C144000%5Cdiv48%3D3000)
Hope this helped!
You would subtract x from each side. It would then be 3y=-x-15. Then you would divide all of the equation by 3. Your final answer would be y=-3x-5.
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )
m =
=
= ![\frac{-14}{0}](https://tex.z-dn.net/?f=%5Cfrac%7B-14%7D%7B0%7D)
Since division by zero is undefined then the slope is undefined
Answer y=-4
Because it's like you do if backwards
