Answer:
130
Step-by-step explanation:
Times 40 & 3 to get 120.
Then as 1 is equal to 1/4 and 4 is equal to 4/4 which is a whole.
As 4 = 4/4 or 1 whole.
Count by 4 with your fingers until you get 40. Which is ten.
Then add 120+10 which equals to our answer that is 130.
You divide $4.55 by 7.
$0.65 times 9 = $5.85
Since someone answered wrongly I'll try to give the correct answer without the given xs. It won't matter. We're looking for a set of points which satisfy
y = f(x) = x² + 3
A. f(7)=7² + 3 = 52, not -2, so not A.
B. f(-2)=(-2)² + 3 = 7, not 1, so not B
C. f(-2)=7, that's good so far.
f(-2)=(-1)²+3=1+3=4, good
f(0) = 0²+3 = 3, good
f(1)=1²+3 = 4, good
f(2) = 2²+3 = 7, good
Answer: C
We'll rule out D. f(1)=1²+3=4, not -2, so not D.
Step-by-step explanation:
it's long there's some calculations in de side hope its helpful
20-30 and 40-50 have ranges of 1.
