The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7

Hi there!
Your answer is:
996 students were apart of this survey!
Step-by-step explanation:
3 out of 4 students means that 75% of students prefer the assemblies be held on Friday.
If 75% = 747 students then:
/75
1% = 9.96 students
×100
100% = 996 students
I hope this makes sense!
Answer:
Step-by-step explanation:
Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick. Let's actually solve the problem!
Equation A: (5/3)x + 3y = 12
Equation B: 4x - 3y = 8
---------------------------
(5/3 + 12/3)x = 15 Note how this has eliminated the variable
(17/3)x = 15 y.
x = (3/17)(15)
