Answer:
-7 is your answer
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other.
4 + y = -3
Subtract 4 from both sides
4 (-4) + y = -3 (-4)
y = -3 - 4
y = -7
-7, or (D) is your answer

Answer:
Step-by-step explanation:
Given
Paper = 20 slips
Word: PENNSYLVANIA
Required
Determine P(Multiple of 4 and V)
The sample size of the 20 slips is:
The outcomes of multiples of 4 is:
So, the probability of multiples of 4 is:
The sample size of PENNSYLVANIA is:
The outcome of V is:
So, the probability of V is:
So, the required probability is: P(Multiple of 4 and V)
Express as percentage
Answer:
x=2.4650
Step-by-step explanation:
I assume that you mean 
so let s use the ln() function
so x = ln(15)/ln(3)
x = 2.4650
Answer:
Part A
to the 10th power will be positive and to the 11th power is negative. When the exponent is even it will be positive. When it is odd it will be negative
Part B
The one with the negative enclosed will be positive. The second one, the exponent is only effecting the number and not the sign. The outcome will always be negative.
