Answer:
f^(-1)(x) = \frac{-1}{5} (x+4)
Step-by-step explanation:
Given is a function
To find its inverse.
We must check whether f is one to one or onto first
If -5x1-4 = -5x2-4 we get x1=x2
Hence f is one to one
Also for every f(x) we can find a x so f is onto.
So inverse exists
Let
Replace x by f inverse and y by x
Answer:
3
Step-by-step explanation:
since the diagonal are equal in length
6x-8=2x+4
4x=12
x=3
Answer:
Larger angle: 80 degrees
Smaller angle: 10 degrees
Step-by-step explanation:
complementary angles = two angles that add up to 90 degrees
x = larger angle
x + x - 70 = 90 Add like terms
2x - 70 = 90 Add 70 on both sides
2x = 160 Isolate the variable by dividing 2 on both sides
x = 80
x = larger angle , 80 degrees
x - 70 = smaller angle , 10 degree

Answer:
area of square=l²
25sq.cm²=l²
l=5sq.cm
area of trapezium =(1/2)(a+b)h
a=5,b=(12+5)=17,h=5
area of trapezium=(1/2)(22)(5)
area=55cm²
