Answer:
Step-by-step explanation:
5x21 = 105
105/2 = 52,5
Hank: The y-intercept of a linear function is the same as the first term of an arithmetic sequence.
Hank's reasoning is being questioned for assuming that all sequences start with 1 and that the y-intercept of a linear function is always at x=0.
Given that,
Hank's reasoning is being discussed.
The claim is that Hank's reasoning is incorrect.
The reasoning involves sequences that begin with the term number 1, where x=1.
By convention,
The first term of a sequence starts with n = 1 instead of n = 0.
This is so n = 1 matches with 1st,
n = 2 matches with 2nd, and so on.
In contrast,
The y-intercept always occurs when x = 0.
So y = 3x+5 has a y-intercept of 5 when you plug in x = 0.
An arithmetic sequence:
f(n) = 2n+7 has its first term when n = 1.
So, the first term would be f(1) = 2(1)+7=9 instead of 7 as Hank claims.

The complete question is:
Hank's reasoning is incorrect because all sequences begin with the term number 1, which translates to x=1.
The y-intercept of a linear function is when x=0.
By convention, the first term of a sequence starts with n = 1 instead of n = 0. This is so n = 1 matches with 1st, n = 2 matches with 2nd, and so on.
In contrast, the y intercept always occurs when x = 0. So something like y = 3x+5 has a y intercept of 5 when you plug in x = 0.
An arithmetic sequence like f(n) = 2n+7 has its first term when n = 1. So the first term would be f(1) = 2(1)+7 = 9 instead of 7 as Hank claims.
Answer:
(C)=0631
Step-by-step explanation:
Kwh is the unit of measurement which is equal to the amount of the energy being used or the amount of energy you are using.
In order to get the readings of kwh of the electric meter, take the smallest reading when there are numbers from 0 to 9 and zero is always taken if the meter points between the number 9 and 0.
Hence, from the given meter, the first meter points between 0 and 1, thus reading will be 0 as 0 is the smallest of the two. Next, the reading is between 6 and 7, therefore the reading will be 6. similarly, the rest readings will be 3 and 1. Therefore, the correct reading will be: 0631

Answer:
B
Step-by-step explanation:
point-slope formula: y-y1 = m(x-x1)
y1 = 4 ; x1 = -2 ; m (slope) = 3
plugging it in to the formula, you get y-4 = 3(x-(-2)
then you get y-4 = 3(x+2)
