Answer:
y = x/3 - 2 or f(x) = x/3 - 2
Step-by-step explanation:
f(x) = y
y = 3x + 6
To solve for inverse change y to x and x to y and solve for y.
x = 3y + 6 //Subtract 6 on both side
x - 6 = 3y //Divide 3 on both side
x/3 - 6/3 = y //Simply
y = x/3 - 2
Answer:
79.77%
Step-by-step explanation:
P(X≥120) = normalcdf(120,1e99,130,12) = 0.7976716754 ≈ 0.7977 = 79.77%
Therefore, about 79.77% of operations last at least 120 minutes
Answer: a sperm and an egg
Step-by-step explanation:
Your inequality is (x being number of people):
175≥35+10x+3x
First, combine like terms so your new inequality is:
175≥35+13x
Then subtract 35 from both sides which makes it:
140≥13x
then divide 140 by 13 making it:
<span>10.769≥x
</span>But because you can't have .769 of a person the actual answer is 10
then you have to subtract 1 because he isn't including himself and there is the answer!:
9≥x
