I need a little help -
OverLord2011 [107]

Answer:

(6x6x6x6) x (6x6x6)

Step-by-step explanation:

6 to the power of four is just 6 multiplied to itself 4 times.

6 to the power of three is just 6 multiplied to itself 3 times.

So, you would be multiplying 6, 7 times.

You could check it with a calculator. - 6^4 x 6^3 = 279936.

6^7 = 279936.

Which equation has the least steep graph? A. y = x + 6 B. y = -x - 9 C. y = 2x + 1 D. y = -7x - 2
maria [59]

Answer:

A and B.

Step-by-step explanation:

<h3>To get to know the graph with least slope, we have to write all equations in the form <u>y=mx + c. </u></h3>

where m is the slope and c is the the y-intercept.

A. y = x + 6

For this equation m = 1

B. y = -x - 9  

For equation B, m = -1

C. y = 2x + 1  

In this equation, m = 2  

D. y = -7x - 2

In equation D, m = -7

The equation with the highest slope is D while the one with the least slope/steep is <em>A and B.</em>

The hundreds digit and the ones digit of a three digit number are the same. The sum of its tree digits are 16. If the tens digit
tensa zangetsu [6.8K]
<h2>727</h2>

Step-by-step explanation:

       Let us denote the three digit number by abc, where a is the hundreds digit, b is the tens digit and c is the ones digit.

       Hundreds digit = a = Ones digit = c

       Sum of digits = a+b+c=16

       So, 2c+b=16

       On exchanging tens and ones digit, value increases by 45. So acb is 45 greater than abc.

       acb-abc=45

       100a+10c+b-100a-10b-c=45\\9c-9b=45\\c-b=5

       2c+b=16,c-b=5\\3c=21\\c=7=a\\b=2

∴ Required number is 727
