Answer: b; y intercept between 8 and 4
Step-by-step explanation:
1. a; 2/3
2. b; 3, all real numbers except x=2
3. a; $.75
4. c; intercepting at (-3,-3)
5. b; 5
6. a; starts at 3
7. b; 1975
8. b; y intercept between 8 and 4
The mean should be about the same, because the sample is random
Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33
Answer:
$38.40
Step-by-step explanation:
to get your total you multiply
48 x 20% =9.60
then you subtract 48.00 - 9.60 = $38.40
A garph y=2 represents a line parallel to the x axis with the y coordinate equal to 2.
The point which lies on the y=2 graph has its y coordinate equal to 2.
In the given options, (3,2) is the coordinate with the y coordinate equal to 2.
Hence, (3,2) lies on the graph of y = 2.
Option (D) is the answer.
