You can just merge the numbers together. So 8 and -12 will be 4. And you can leave the N alone.
So your left with:
N+4

If that’s not right, it’s:
N^2+4

Simplify each expression. Type your answer into the box. (8 – 4)2 x |4 – 8| =
elena55 [62]

Answer:

-32

Step-by-step explanation:

First you have to solve the numbers in the parenthesis which would be (8-4)= 4 then there is a 2 that you have to multiply which would be 4x2=8, then you have to solve the other parenthesis (4-8)=-4 so then you end up with 8x-4 which equals -32

P=3y/q solve for y make sure to add steps pls
Likurg_2 [28]

Answer:

Solving for y gives:

y = \frac{pq}{3}

Step-by-step explanation:

Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.

Given equation is:

p = \frac{3y}{q}

Multiplication property of equality(Multiplying both sides by q)

p*q = \frac{3y}{q} * q\\pq = 3y

Division property of equality(Dividing both sides by 3)

\frac{pq}{3} = \frac{3y}{3}\\\frac{pq}{3} = y

Hence,

Solving for y gives:

y = \frac{pq}{3}

How do you evaluate logarithms? Explain using an example or mathematical evidence to support your answer.
kenny6666 [7]

Answer: Explanation below.

Step-by-step explanation:

First of all you need to know how to convert a logarithm into an exponential expression. The property is:

log_Bx=n

This is the same as: B^n=x

Example 1:

log_99=

We are trying to find what to raise 9 to, in order to get a result of 9.

9^x=9

When you have same bases, you equal exponents.

x=1

Therefore; log_99=1

Example 2:

log_232=

2^x=32

In this case, we have to make sure both sides have the same base. 32 can have a base of 2 if expressed as: 2^5 which is 2*2*2*2*2

Rewriting this example we have;

2^x=2^5

Since we have the same base, we equal exponents.

x=5

Therefore; log_232=5

Example 3:

log_3729=

3^x=729

729 can have a base of 3 if expressed as: 3^6

3^x=3^6

x=6
