Answer:
B) y² = 4x; There are two outputs for each input
Step-by-step explanation:
For an equation to be called a function, the input values for x must only result in a single output for y.
Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.
The only exception is the function y²= 4x
For this function, for any value of x, there will be more than one output for y. Take x = 1 for example
y² = 4(1)
y² = 4
y = ±√4
y = ±2
This shows that y = 2 and -2
Also if x = 4
y² = 4(4)
y² = 16
y = ±√16
y = ±4
y = 4 and -4
No matter the value of x imputed, the output value y will always be two (a positive and a negative value)
Hence, option B is correct.
M + f + a = 82
m = 7a + 1
f = 1/2m.....f = 1/2(7a + 1).....f = 3.5a + 0.5
7a + 1 + 3.5a + 0.5 + a = 82
11.5a + 1.5 = 82
11.5a = 82 - 1.5
11.5a = 80.5
a = 80.5 / 11.5
a = 7......7 adults
m = 7a + 1
m = 7(7) + 1
m = 49 + 1
m = 50 <=== 50 male students
f = 1/2m
f = 1/2(50)
f = 25 <=== 25 female students
11= x because if you simply the question you get 13= x+ 2 and then you subtract 2 from each side and cross out the 2 from 2/2 and get left with 11=x
Answer:
The answer is C. a = -4,000 m
Step-by-step explanation:
If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m
