Answer:
I'm pretty sure your answer would be B
Step-by-step explanation:
The teacher wants answers from all the students but it would take to long to ask every single person so it would only make sense to ask every boy in each grade
What you're really doing is finding the slope of the line between two points you need to calculate.
Because a=3, you're told that one point will always be (3, f(3)).
The second point will be (3+h, f(3+h)).
For the first point, f(3) = 7/3, so your first point is always (3, 7/3).
<u>For h=1</u>
The x-value of your second point is a+h, or 3+1 = 4 in this case.
f(4) = 7/4.
So the average rate of change, aka the slope of the line between (3, 7/3) and (4, 7/4), is the usual slope formula:
In this h=1 situation, that becomes:
You're repeat this process for each new h-value.
Answer:
x=0
Step-by-step explanation:
You start off with 2*2+x-4=0 (I may have read the question wrong)
Simplify: 4+x-4=0
Simplify again lol: x=0
x=0
Y=4x-5
Y=3x+4
Plug in each choice:
(9,31)
31=4(9)-5 ——— 31=36-5 TRUE
31=3(9)+4——— 31=27+4 TRUE
(9,31) must be the answer but let's try the other choices to be sure...
(-9,31)
31=4(-9)-5 ——— 31=-36-5... =-41 FALSE
(-9,-31)
-31=4(-9)-5 ——— -31= -36-5...=-41 FALSE
(9,-31)
-31= 4(9)-5 ——— -31= 36-5... =31 FALSE
SO THE CORRECT ANSWER = (9,31)
650 millimeters
10 multiplied by 65 is 650.
