Brainliest Simplify completely 14x^5+21x3y2/7x^3y
olga_2 [115]

If the given expression is simplified we get c. 2x²y³ + 3y.

Explanation:

  • The numerator has two terms while the denominator only has one term. We divide the numerator terms each separately with the denominator term.
  • So 14x⁵y⁴ + 21x³y² / 7x³y becomes 14x⁵y⁴ / 7x³y + 21x³y² / 7x³y.
  • The simplification of the first term; 14 / 7 = 2, x⁵ / x³ = x², y⁴/y = y³. So the first term is 2x²y³.
  • The simplification of the second term; 21 / 7 = 3, x³ / x³ = 1, y² / y = y. So the second term is 3y.
  • Adding both the terms we get 2x²y³ + 3y. This is the option c.

The license plates on all karts in MarioLand contain three numbers followed by three letters. If you know that the MarioLand num
iogann1982 [59]

Answer:

It can be created 1575 license plated with at least one three-piece palindrome.

Step-by-step explanation:

If a license plates has at least one three-piece palindrome, we have the following cases:

1. The license plate just has a palindrome in the three numbers: The number license plates for this case can be calculated using the rule of multiplication as:

<u>   5              </u>*<u>      5      </u>* <u>      1       </u>* <u>        3         </u>*<u>      3       </u>*<u>      2       </u>=  450

1st Number        2nd        3rd          1st Letter       2nd           3rd

For have a palindrome in the numbers, the first and the 3rd number need to be the same. So, we have 5 digits for the first and the 2nd Number and one digit for the 3rd Number.

On the other hand, if the palindrome is just in the numbers, the 3rd letter need to be different from the 1st. So we have 3 options for the 1st and the 2nd letter and 2 options for the 3rd letter.

At the same way, we can calculated the number of license plates for the other cases:

2. The license plate just has a palindrome in the three letters:

<u>   5              </u>*<u>      5      </u>* <u>      4       </u>* <u>        3         </u>*<u>      3       </u>*<u>      1       </u>=  900

1st Number        2nd        3rd          1st Letter       2nd           3rd

3. The license plate has a palindrome in the three numbers and in the letters:

<u>   5              </u>*<u>      5      </u>* <u>      1       </u>* <u>        3         </u>*<u>      3       </u>*<u>      1       </u>=  225

1st Number        2nd        3rd          1st Letter       2nd           3rd

Then, It can be created 1575 license plates with at least one three-piece palindrome and it is calculated as:

450 + 900 + 225 = 1575

slope-intercept form for the line that passes through (-1,-7) and is perpendicular to the graph of 3x+12y=-6
Mrac [35]

Answer:

Step-by-step explanation:

We first need to find the slope of the given line.  Putting that standard form of a line into slope intercept:

12y = -3x - 6 so

y=-\frac{1}{4}x-\frac{1}{2}

In this form we can easily determine that our slope is -1/4.  That means that the perpendicular slope, the opposite reciprocal, is +4.  We will write first the point slope of the new line using our given point, then solve it for y, putting it into slope-intercept form.  y - (-7) = 4(x - (-1)) and

y + 7 = 4x + 4 so

y = 4x + 4 - 7 so

y = 4x - 3
