Answer:

93.15

Step-by-step explanation:

Multiply 230.00 dollars and 0.55 = 126.50

Subtract 230.00 dollars and 126.50 = 103.50

Multiply 103.50 and 0.10 = 10.35

Subtract 103.50 and 10.35 = 93.15

Find the equation of the line that passes through he points (2,6) and (-2,4)
stepan [7]
First Find slope by using \frac{y2-y1}{x2-x1}

\frac{4-6}{-2-2} = \frac{-2}{-4} =  \frac{1}{2}

Now use point Slope form to find the equation of the line (y-y₁)=m(x-x₁)
(y-6)=\frac{1}{2}(x-2) 
y-6=\frac{1}{2} x-1
y=\frac{1}{2} x+5 is your equation

4^3 * 4^4 = <br> A) 4^-1<br> B) 4^1<br> C) 4^7<br> D) 4^12

<h2>Hello!</h2>

The answer is:

The correct option is:

C) 4^{3}*4^{4}=4^{7}

<h2>Why?</h2>

To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

a^{m}*a^{n}=a^{m+n}

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.

So, we are given the expression:

4^{3}*4^{4}

We can see that both powers have the same base (4), so solving we have:

4^{3}*4^{4}=4^{4+3}=4^{7}

Hence, we have that the correct option is:

C) 4^{3}*4^{4}=4^{7}

Have a nice day!

What would I to the 8th power be?
FromTheMoon [43]
I think it'd be 1 because well all you are doing is multiplying 1, 8 times. That is only if you meant the I to be 1.
