Which expression is equivalent to 36^-1/2

inn [45]

ANSWER

$( {36})^{ (- \frac{1}{2}) } = \frac{1}{6}$

EXPLANATION

The given expression is

${36}^{( - \frac{1}{2} )}$
This is having a negative index. We must first of all change to a positive index.

Recall that,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this law of exponents to get,

${36}^{( - \frac{1}{2} )} = \frac{1}{ {36}^{( \frac{1}{2} )} }$

We cab rewrite the given expression to obtain;

${36}^{( - \frac{1}{2} )} = \frac{1}{ \sqrt{36} }$

This will simplify to give us,

${36}^{( - \frac{1}{2} )} = \frac{1}{ 6 }$

Solve x+y=7 and 3x-2y=11 using elimination

BartSMP [9]

X=5 and y =2.
Here's how you do it.
Multiply the first equation by -3, and the second one by 1.
add the equations to eliminate x.
then solve for y by dividing both sides by -5, which gives us 2.
to solve for x subsitute 2 in for y.

Answer:

S= 4000n+50000

Step-by-step explanation: Table

50000+4000=54000 0 5000

54000+4000=58000 1 54000

58000+4000=62000 etc.. 2 58000

3 62000

Is increasing by 4000 and thats the rate of change so S=4000n

And the y intercept always will be with a 0 in the cordinates and the only with a 0 is 50000.

We put all together and it will be

Answer: S=4000n+50000
