Hey there! I'm happy to help!

Let's plug in the values for a and b.

50(2)-2(20)+6

If a number is next to the parentheses you multiply.

100-40+6

60+6

Have a wonderful day! :D

<h3>You should pick:</h3>

The relationship is linear because each y-value is 5 more than the one before it.

<h3>Here's why I think so:</h3>

If we look at the relationship between the x values and the y values, we can tell that they both increase periodically. The x values increase by 1('s), while the y values increase by 5('s).

Think about it. If y starts off at 5 when x is at 0, and then goes to 10 by x becomes 1, and increases another 5 values when x increases by 1 (again), then we are witnessing a pattern. For every 1 x value, y increases by another 5 values. Such a repetitive relationship will clearly be shown with a line. Thus, the relationship is a linear one.

Since we know that the relationship of the table is linear, and that it is linear due to the fact that the y-value continuously increase by 5's without fail, the only answer that would make sense is the second one.

Therefore, the answer is 'The relationship is linear because each y-value is 5 more than the one before it.'

What is the value of x so that the mean is 5. 7, x, 5, 3, 2

VLD [36.1K]

Answer:

Step-by-step explanation:

The 'mean' is the same as the 'average'

( 7 + x + 5 + 3 + 2) / 5 = 5

7+x+5+3+2 = 25

x = 8

Explain how the Quotient of Powers Property was used to simplify this expression.

Strike441 [17]

Answer:

$\frac{5^{4}}{25} = 25$

Step-by-step explanation:

I'm not sure if you had a typographical error with this statement, "5 to the fourth power, over 25 = 52."

According to the Quotient Rule of Exponents:

$\frac{a^{m}}{a^{n}} = a^{(m-n)}$

Method 1:

In order for you apply the Quotient Rule, the base must be the same. Since 5 is a factor of 25, then you could rewrite 25 as 5². Doing so will give you the following exponential expression:

$\frac{5^{4}}{5^{2}} = 5^{(4 - 2)} = 5^{2} = 25$

Method 2:

Even if you solve the given problem manually, you'd still get the same answer:

$\frac{5^{4}}{25} = \frac{5*5*5*5}{25} = \frac{625}{25} = 25$

Both methods produced the same result, proving that the correct answer is 25.

Please answer the question as the directions say and try your best :D

False: The relation is a function because for each X value there is only one Y value.

True: The domain is the x values
The lowest X value is 3 and the highest X value is 8
So 3<= x <= 8 is true

True: The range of a function is the Y values, which are 6,7,8,10
