First we subtract 100 - 35 to get 65. (Because 35% is out of 100%)
Since we already know there are 117 students, we can automatically assume 65%= 117
<span>117 is 65% of what? 
We use this formula to find out: y</span><span>/p% = x
</span>Plug in the numbers so it's now 117/65%= x
Or to make it easier, 65% is also 0.65 (you can find by dividing 65/100)
So now we have 117/0.65= x
Work that through to get x= 180
Hope that helps!

Write a quadratic function that has been translated 1<br> units to the right and 3 units down.
vodka [1.7K]

Step-by-step explanation:

Hi,

f(x) = (x - 1) - 3

The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)

And the -3 is not embedded with the x, meaning the function will move 3 units down.

I hope this helps :)

Beyonce is solving a system of equations:
Sholpan [36]

Answer:

Beyonce will get the same result.

Step-by-step explanation:

The given system is

2x-3y=-2

and 4

x+y=24

This system contains two lines that are not parallel to each other therefore the solution x=5, y=4 is unique.

It doesn't matter which method he used or which variable he eliminated first.

The solution will still be the same.

If the system of two equations with has no solution, the Beyonce will not get a solution in the first place, but the fact that the system has no solution remains the same even if Beyonce uses a different method.

If there are infinite solutions, Beyonce might get different solutions using a different method, but the fact that the system has infinite solution remains the same.
