Answer:
The square root of -1 is i
We can find the number of extra clubs in the deck from the given probability, since the probability of drawing a diamond and a club is

but this would imply that

, which suggests we're taking 4 clubs out of the original deck and contradicts the problem statement that there are "too many clubs".
Perhaps the question is providing the probability of drawing a diamond, THEN a club, or vice versa. In that case, we have

and solving gives

, which makes more sense. Then the number of extra spades in the deck must be 2.
Answer:
She walked neighbor's dog 4 times.
Step-by-step explanation:
It is given that:
Peri earned $27 for walking the dogs 3 times.
Unit rate =
Unit rate = $9 per dog
Now,
Peri worked at the same rate and earned $36.
Unit rate = 

d= 36/9
d = 4
Therefore,
She walked neighbor's dog 4 times.
Answer:
y=2x-5
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
m=2
b=-5
Answer:
Step-by-step explanation:
y = mx + b
in this form, the constant of proportionality is also known as the slope....and it can be found in the m position
y = 3x.....is actually y = 3x + 0....so the slope (constant of proportionality is gonna be 3
