Answer:
160
Step-by-step explanation:
With the problem, it's best to put this into a fraction
8/20 of every student will be absent from school less than five days a year, which can then be simplified to 2/5.
There are multiple ways to go about this problem, but my preferred way is to then take 1/5th of 400, which can be done by taking 1*400/5 which equals 80. Since we are asking for 2/5's, just multiply that number by 2, which gives us 160 students.
2 times x and -5
2x-10-6x=-22
Then do 2x +-6x
-4x-10=-22
Next, 10 + -22
-4x=-12
Divide the 12 by 4
X=3
<h3>f(2)=-2(2-4)²</h3><h3>f(2)=-2(-2)²</h3><h3>f(2)=-2(4)</h3><h3>f(2)=-8</h3>
<h2>(2,-8)</h2>
