The function that correctly returns grades from 60 percent to a 100 percent is f(x) = [[(x - 50)/10]]
<h3>How to determine this function</h3>
The question tells us that the students do not fail and they do not get a 100 percent score either.
Hence there is no need for worry if the grade is at 5.0 or less than 1.
For example we have
x = 82.976
f(82.976) =[[(82.976-50)/10]
This would then be 3.29
This is then = 3.0
This function is not an odd function and it is not an even function. This is because the domain does not have negative values.

The area of a circle is r^2pi and 2r = diameter. Thus r=diameter/2
r=6/2= 3 inches so the expression is 3^2*3.14 so I believe it's B
I'm not sure if this is a trick question but 1/2 because there are 2 options(yellow or blue) and one desired outcome(yellow)
To find this, you have to turn them into inproper fractions. You do this by doing denominator x whole number x numerator. The equation is now 14/3 x 27/4. You have to do numerator x numerator and denominator x denominator which will lead us to an answer of 378/12 or 31 6/12 or 31 1/2
Answer:
x=-2
y= 8
Step-by-step explanation:
Given data
10x – 2y = -36-----------1
7x – 2y = -30--------------2
-Subtract to eliminate y
3x-0= -6
3x= -6
x= -6/3
x= -2
Put x= -2 in
7(-2)– 2y = -30
-14-2y=-30
-14+30=2y
16=2y
y= 16/2
y= 8
