Answer:
It would really depend on what the choices were.
Step-by-step explanation:
Given function:
f(x) = 2 - 5x
Table;
x f(x)
-2 12
-1 7
0 2
1 -3
2 -8
The function is f(x) = 2 -5x
For; x = -2; f(x) = 2 - 5(-2) = 12
f(x) = 2 - 5(-1) = 7
f(x) = 2 - 5(0) = 2
f(x) = 2 - 5(1) = -3
f(x) = 2 - 5(2) = -8
Answer:
Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.
Answer:
A
Step-by-step explanation:
Given that the cones are similar then corresponding dimensions are in proportion, that is
= 
( cross- multiply )
12x = 6 ( divide both sides by 12 )
x = 0.5 → A
Answer:
B
Step-by-step explanation:
The smaller one is divided by 2 and is reflected around the y-axis
