You'd have no problem simplifying that expression if it said
-(5 cows) - (1 cow) + ( 14 cows) - (3 cows) .
You'd just add up the cows, and simplify the expression to say
5 cows .
When you see an expression that talks about 'x's instead of cows,
you get scared. It has something to do with algebra and math and
all that stuff, so you freeze.
Relax. Just make each 'x' a cow, and suddenly it almost solves itself.
The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
The correct option is (A).
What is the average rate of change of a function?
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.
Using function notation, we can define the Average Rate of Change of a function f from a to b as:

The given function is
,
Now calculating the average rate of change of function from x = 1 to x = 2.

Now, calculate the average rate of change of function from x = 3 to x = 4.

The jump from m = 10 to m = 40 is "times 4".
So option (A) is correct.
Hence, The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

Answer:
b
Step-by-step explanation:
the answer is b because you add all those together then boom
The have been saving for 10 weeks.
Given:
Duane = $5 every other week. meaning every 2 weeks
Mick = $2 every week
Amount Saved = $45
First, divide Duane's $5 by 2 to get his weekly contribution.
$5/2 = $2.50
let x be the number of weeks.
Duane + Mick = $45
2.50x + 2x = 45
4.50x = 45
4.50x/4.50 = 45/4.50
x = 10 weeks
to check:
2.50x + 2x = 45
2.50(10) + 2(10) = 45
25 + 20 = 45
45 = 45
Answer:
D. x-intercept is -5 and the y-intercept is -2
