Y ^-7 / y ^-13 20 POINTS PLEASE HELP

Mathematics
1 answer:
kkurt [141]3 years ago
4 0

Answer:

The answer is

<h2>{y}^{6}</h2>

Step-by-step explanation:

<h3>\frac{ {y}^{  - 7} }{ {y}^{ - 13} }</h3>

To solve the expression we use the rules of indices

Since the bases are the same and are dividing we subtract the exponents

That's

<h3>\frac{ {a}^{x} }{ {a}^{y} }  =  {a}^{x - y}</h3>

So we have

<h3>\frac{ {y}^{ - 7} }{ {y}^{ - 13} }  =  {y}^{ - 7 -  - 13}  =  {y}^{ - 7 + 13}</h3>

We have the final answer as

<h3>{y}^{6}</h3>

Hope this helps you

Different shapes are drawn on cards and then the cards are placed in a bag. The number of cards for each shape is shown in the t
Anvisha [2.4K]
We can first add up the cards so we know how many we have in all:
16 + 16 + 18 = 50 cards

We can do this a little bit easier if we get the "16"-cards in one number total.

16 + 16 = 32

\frac{32}{50} = 32 x 2 = \frac{64}{100}
                                         50 x 2 

\frac{64}{100} = 64 : 2 = 32 %
                                            100
We did just divide the % of two types cards on 2, so we get the %-chance of 1 type card.

I am not quite sure, but I think that 32 % is the correct answer.

How do you solve and check x/4 = -5
Mashutka [201]

Rearrange x/4-(-5)=0

Simplify x/4

-5 = -5/1 = -5*4/4

x- (-5*4)/4 = x+20/4

x+ 20/4 = 0

x+20/4 * 4 = 0*4

The equation now takes the shape: x+20=0

subtract 20 from both sides of the equation: x=-20

Answer: x=-20
