Which equation shows the inverse property of multiplication?

2 answers:

4 0

The correct answer is C.

The inverse property of multiplication states that a number multiplied by its reciprocal equals 1. The reciprocal of 1/2 is 2/1, or 2.

C is the correct option.

The purpose of the inverse property of multiplication is to get a result of 1

The answer to this question would be the last choice (this data has no outliers)

Explanation: The reason for this is that an outlier is basically any number or value that kind of stands off or is very separated from a set of data.

For example, if I had the numbers 1,2,3,2,9,5,7,5,8,4 and 47, 47 would definitely be an outlier as it's significantly greater than the rest of the data.

The data shown in your question doesn't vary a lot though, (it's contained within a range of 65 and 80- no number seems to be radically different).

5 + 14 x y = 9 x y - 5

Anon25 [30]

Answer:

xy = -2

Step-by-step explanation:

To solve:

5 + 14xy = 9xy - 5

=> First subtract 9xy from each side of "="

5 + 5xy = -5

=> Now, subtract 5 from each side:

5xy = -10

=> Finally divide 5 on each side:

xy = -10/5

xy = -2

Hope this helps!

Lyn invested $7,000 into a investment paying 3% interest, compounded semi-annually, twice a year. After five years, how much wou

gayaneshka [121]

Answer:

Option B.) $8,123.79

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=5\ years\\ P=\$7,000\\ r=0.03\\n=2$

substitute in the formula above

$A=\$7,000(1+\frac{0.03}{2})^{2*5}$

$A=\$7,000(1.015)^{10}=\$8,123.79$

A bookstore pays $12.75 for hardcover books and charges $29.95. What is the maximum percent of discount that it can offer while

Anna [14]

9514 1404 393

Answer:

A. 40.7%

Step-by-step explanation:

The selling price for a $5 profit will be ...

$12.75 +5.00 = $17.75

From $29.95, this represents a change of ...

(17.75 -29.95)/29.95 × 100%

= -12.20/29.95 × 100% ≈ -40.7346%

The bookstore can offer a maximum discount of about 40.7%.

Which equation represents the function graphed on the coordinate plane?????

Y_Kistochka [10]

Since you haven't provided the graph, I'll explain each one and you choose the one suiting your given.

The parent modulus function is:

g(x) = |x|

It is centered at the origin and opens upwards.

A coefficient inside the modulus |x+k| means that the function is shifted along the x-axis

If "k" is positive, the shift will be to the left. If "k" is negative, the shift will be to the right.

A coefficient outside the modulus |x| + h means that the function is shifted along the y-axis

If "h" is positive, the shift will be upwards. If "h" is negative, the shift will be downwards.

Now, let's check each of the options:

g(x) = |x+4| - 2 :

This function is shifted 4 units to the left and 2 units down. It will be centered at (-4,-2). Check the blue graph in the attachment.

g(x) = |x-4| - 2 :

This function is shifted 4 units to the right and 2 units down. It will be centered at (4,-2). Check the black graph in the attachment.

g(x) = |x-2| - 4 :

This function is shifted 2 units to the right and 4 units down. It will be centered at (2,-4). Check the red graph in the attachment.

g(x) = |x-2| + 4 :

This function is shifted 2 units to the right and 4 units up. It will be centered at (2,4). Check the green graph in the attachment.

All 4 graphs are shown in the attached picture.

Hope this helps :)
