Hope you won't be turned off by a correction, but we really need to use the symbol " ^ " to denote exponentiation.

Thus, we have x^2 = 100

Taking the square root of both sides, we get x = plus or minus 10. Verify, please, that both x = -10 and x = +10 satisfy the given equation.

Step-by-step explanation:

For a line to be parallel it must have the same slope

6x-2y=-5

+5 +5

6x-2y+5 = 0

+2y +2y

6x+5 =2y

/2 /2

3x+5/2=y So the slope is 3 and we know it can only be either B or D

Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D

B. -2= 21-23 TRUE

D. -2 = 21+ 23 FALSE

So the answer is B

Answer:

p=0.05882

Step-by-step explanation:

Probability is the likelihood of an event occurring.

-A standard deck of cards has 4 kings.

#After one card is removed, 51 remains of which 3 are kings:

$P(king)=\frac{3}{51}\\\\=0.05882$

Hence, the probability that the second card is king is 0.05882
