Answer:
f(x) is a one to one function.That maps out one function to another ,and it therefore passes both the vertical and horizontal I ine test
Answer:
1:7
Step-by-step explanation:
Answer:
y = -5x + 7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
5x + y = -2
Random point (2, -3)
Step 2: Rewrite
y = -5x - 2
m = -5
Step 3: Write parallel line
y = -5x + b
-3 = -5(2) + b
-3 = -10 + b
7 = b
y = -5x + 7
Answer:
4 stations
Step-by-step explanation:
If we need to be at least 98% certain that an enemy plane flying over will be detected by at least one station, we must ensure that there is at most a 2% chance that no radar stations detect the plane.
The probability that a single radar station does not detect the plane is 0.35.
For n radar stations:

Rounding up to the next whole station, at least 4 stations are needed.
A function is for every input, there is 1 output
aka
x never repeats with a different y
A. x doesn't repeat, it's a function
B. -8 repeats with 34 and 40, this is not a funciton (this is the answer0
C. x doesn't repeat, it's a function
D. x doesn't repeat, it's a function
answer is B
