Simply substitute the given number for all the equations.
17) 5b + 1 = 16 where b is -3
5(-3) + 1 = 16
-15 + 1 = 16
-14 ≠ 16
So, the given number is not a solution.
19) 2 = 10 - 4y where y is 2
2 = 10 - 4(2)
2 = 10 - 8
2 = 2
The given number is a solution.
21) -6b + 5 = 1 where b is 0.5
-6(0.5) + 5 = 1
-3 + 5 = 1
2 ≠ 1
The given number is not a solution.
Answer:
CI=P*(1 + R/100)^18
A=(CI + P) = P(1+R/100)^18
13500/P=1(100+R/100)^18
A/P=(100+R/100)^18
A/P=(100+R/100)^18
A=13500$ as (750 * 18)
(13500)/P=(1 +1.15/100)18
(13500)/P=(1+1.15/100)18
13500=((1.0115)^18
P=R$10989.02
Step-by-step explanation:
CI=Compound Interest
A=Amount
P=Principal.
Answer:
(0,-1),(1,0),(2,1),(3,2)
Step-by-step explanation:
We are given that a relation
y=x+1y=x+1
We have to find the four points contained in the inverse
The given function is linear function
Therefore,
Domain of function=R
Range of function=R
x=y-1x=y−1
Now, replace x by y and y replace by x
y=x-1y=x−1
Now, substitute y=f^{-1}(x)=f
−1
(x)
f^{-1}(x)=x-1f
−1
(x)=x−1
It is linear function and defined for all real values.
Substitute x=0
f^{-1}(0)=-1f
−1
(0)=−1
Substitute x=1
f^{-1}(1)=1-1=0f
−1
(1)=1−1=0
f^{-1}(2)=2-1=1f
−1
(2)=2−1=1
f^{-1}(3)=3-1=2f
−1
(3)=3−1=2
Therefore, four points contained in the inverse (0,-1),(1,0),(2,1) and (3,2)
This would be a great question to just plug into a calculator. I'm sure you will find the answer quite easily if you use a calculator.
