Answer:
21, 34, and 55 because it's like that one ratio, I forgot the name tho
Answer:
C
Step-by-step explanation: Because Median is all the numbers put in order least to greatest. Then the middle number.
Store A: 15, 25, 45, 55, 64
Store B: 22, 35, 40, 65, 71
Answer:
he just shrugged and *sigh*
Step-by-step explanation:
Answer:
f^-1 (x)=x/3
Step-by-step explanation:
y=3x
x=3y
y=x/3
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
