So we got the function of the graph f(x) = 2^x + 1 what you will need to do first is find the y-coordinates corresponding to x=1 and x=3 which can be found by substituting into the function. After that we can find the average rate of change using y2-y1/x2-x1.
f(1)=2^1+1 which would be equal to 3
1,3
f(3)=2^3+1 which would be equal to 9
3,9
9-3/3-1=6/2
6/2=3
The average rate of change is 3.
12 1/2 - 5x = 3 1/3
12 1/2 - 3 1/3 = 5x
9 1/6 = 5x
x = (9 1/6) / 5
x = 1 5/6
1 5/6 pounds
Answer: y=3x-7
Step-by-step explanation:
First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative
Then since you're trying to find the line that is parallel you use the same slope which is 3x
You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept
You then solve as normal and get y=3x-7
I am pretty sure this is correct
Step-by-step explanation:
PUTTING THIS EQUATION INTO SLOPE INTERCEPT FORM MEANS EXPRESSING IN FORM
Y = MX + C
-4x +2y = –12
adding 4x to both sides
=> 2y= 4x –12
dividing the whole equation by 2
y=2x –12
HENCE, EXPRESSED IN THE REQUIRED FORM.
hope this helps :)
Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 22.3
Sample standard deviation = 8.8
We want to estimate 92% confidence interval.
92% Confidence interval:
Putting the values, we get,
Degree of freedom = n - 1 = 63
