Answer:
C. (9, 18)
Step-by-step explanation:
Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...
(9, 15)
Then the translation up by 3 will give you the image coordinates ...
(x, y) ⇒ (x, y+3)
(9, 15) ⇒ (9, 15 +3) = (9, 18)
The coordinates of R' are (9, 18), matching choice C.

<em>Comment on multiple choice answers</em>
As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.
Number 4 is C because when you do 28 times 5 your get 140 then you do 140 divided by 20 to get 7 when you do proportions to find the missing number you cross multiply with the numbers there and divide with the number that is across from the missing
Number 5 is $6 because to find the missing number you have to see which way makes sense you could do 4 divided by 3 but you get a really long number so if you do 3 divided by 4 you get .75 and you get .75 for all cost is usually the y-axis so you do y divided x so then do .75 times 8 to get the answer
Number 6 to plot them you just go in the middle of the line for the first because it is not directly 2
Number 7 to change a fraction to decimal do the numerator divided by denominator even if the denominator is bigger so 6 divided by 25 is .24 for decimal form to get the percent move the decimal point two places to the right so it will be 24%
Answer:
m ≥ 0
Step-by-step explanation:
Since the cost is represented by c = 0.12m, the domain should be a positive number, this is because number of minutes can't be written in negative. Therefore, the most reasonable number for the domain would be the set of positive whole numbers which means, m≥0.
Answer:
1.1万
Step-by-step explanation:
Base Surface Area = 22
= 4 yards^2
Lateral Surface Area =
2×2√(2/2)^2 + 3^2
2
= 12.649110640674 yards^2
Total Surface Area = 16.649110640674 yards^2
Your Answer: 16.60 rounded to the nearest tenth.
