To get the class midpoint or the middle value of this problem, we need to get the average of the lower class and the upper class.So in formula it is = upper + lower / 2Our lower class is 0 while the upper class is 4. So 4 + 0 = 4/2 = 2 would be the answer.

I hope this helps you




1)


x/4=14-10


x=4.4


x=16


2)


2.2-2x.2= -3x



4-4x= -3x


x=4



3)


3,75x-1,75x=1,7-3,7

F(x) = -9x + 7 find f(3) HELPPP
Viefleur [7K]
<h3>Given :-</h3>
  • f(x) = -9x + 7 .

<h3>To Find :-</h3>
  • The value of f(3) .

<h3>Solution :-</h3>

The given function is ,

→ f(x) = -9x + 7 .

And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,

→ f(3) = -9*3 +7

→ f(3) = -27+7

→ f(3) = -20

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u>-</u><u>2</u><u>0</u><u> </u><u>.</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em>.</em>
