The answer is 1.
If you put -1 instead of x, then you can get 1.
2(-1)+3=y
-2+3=y
1=y
Answer:
Proved!
Step-by-step explanation:
For two functions f(x) and g(x) to be inverses of each other then;
f(g(x)) = x and g(f(x)) = x condition must be satisfied.
<u>Checking: A. f(x) = 7x³ + 10 and g(x) = ∛</u><u />
<u />
So f(g(x)) = 7()³ + 10
We get; 7() + 10 = x - 10 + 10 = x (*<em>This is correct!)</em>
<em />
So g(f(x)) =
Ten cancels out and we are left with;
= = x (* <em>This is also correct!)</em>

Answer:
(12^2)+(4^2)=160
=Large side of a rectangle
(2^2)+(6^2)=40
=small side of a rectangle
area
Step-by-step explanation: 12*4=48/2=24Large triangle area
2*6=12/2=6 small triangle area
Two large triangles=2*24=48
two small triangle=2*6=12
48+12=60
Largerectangle area=14*10=140
140-60=80
Answer:
(25.732,30.868)
Step-by-step explanation:
Given that in a random sample of 42 people, the mean body mass index (BMI) was 28.3 and the standard deviation was 6.09.
Since only sample std deviation is known we can use only t distribution
Std error =
t critical for 99% two tailed
Margin of error
Confidence interval lower bound =
Upper bound =
