Answer:

7y-15=-29

The steps to solve this is as follows:

Adding 15 to both sides;

7y-15+15=-29+15        (Addition Property of Equality)

=> 7y =-14

Diving by 7 on both sides we get;

\frac{7y}{7} =\frac{-14}{7}    (Inverse Property of  Multiplication)

Finally we get;

y= -2

What is the distance from the origin to point A graphed on the complex plane below?
ExtremeBDS [4]
Distance between two points is
Root of X2 - X1 squared + Y2 - Y1 squared
So here X2 is 0 X1 is 0 as the origin is 0,0
Root of Y2-Y1 squared is what we are left with
Root of -2- -3 squared
Root of 1 squared
Root of 1
Which is 1
Distance is 1

Given that sin 2x = cos(2x - 30). Find the value of tan x.​
Paul [167]

Answer:

x=30o+n90on∈Z

Step-by-step explanation:

cos2x=sin(90o−2x)=sin(2x−30o)

Which mean 90o−2x=2x−30o+n360o

or 90o−2x+2x−30o=(2n+1)180o

The later cannot be true.

so x=30o+n90on∈Z

3. In a game, if you roll a 6 on a 6-sided number cube, you lose a turn.
dlinn [17]
Part A: The probability is 1/6. This is because there are six options in total, and only one of those options is 6.

Part B: The probability is 6/6, or alternatively 100%. This is because that the probability of rolling a 6 is 1/6, and the probability of rolling any of the other options is 5/6. Adding them together gives a probability of 6/6.

Part C: The probability is 5/6. This is because there are six options, and of those, five of them are not 6.
