6/7Y - 18/28 =-15/14
First, let's get a common denominator
24/28Y - 18/28 =-30/28
Move your terms to isolate Y
24/28Y=-12/28
Multiply by 28 on both sides
24/Y=-12
Times both sides by Y, then divide by -12
24/-12=Y
Simplify
-2=Y

I hope this Helps!

Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)
SIZIF [17.4K]

Answer:

f(-1)=19

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

f(x)=3x^2+16

Find f(-1):

f(-1)=3(-1)^2+16

f(-1)=3(1)+16

f(-1)=3+16

\boxed{f(-1)=19}

Two cards are drawn in succession and without replacement from a standard deck of 52 cards. Find the probability that the second
Svetllana [295]

Answer:

The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497

Step-by-step explanation:

Total number of face cards = 12

Total cards = 52

Probability of getting face card on first draw=\frac{12}{52}

Remaining no. of face cards = 11

Remaining number of total cards = 51

Probability of getting face card on second draw=\frac{11}{51}

The probability that the second card is a face card if it’s known that the first card was a face card =\frac{12}{52} \times \frac{11}{51}= \frac{12}{52} \times \frac{11}{51}=0.0497

Hence The probability that the second card is a face card if it’s known that the first card was a face card is 0.0497
