What is the quotient
mario62 [17]

Answer:

The quotient is 3x - 11 + 60/(x + 5) ⇒ 2nd answer

Step-by-step explanation:

* We will use the long division to solve the problem

- The dividend is 3x² + 4x + 5

- The divisor is x + 5

- The quotient is the answer of the division

- If the divisor not a factor of a dividend, the quotient has

  a remainder

* Lets solve the problem

- At first divide the first term in the dividend by the first term in

 the divisor

∵ 3x² ÷ x = 3x

- Multiply the divisor by 3x

∴ 3x (x + 5) = 3x² + 15x

-Subtract this expression from the dividend

∴ 3x² + 4x + 5 - (3x² + 15x) = 3x² + 4x + 5 - 3x² - 15x = -11x + 5

- Divide the first term -11x in the new dividend by the first

 term x in the divisor

∴ -11x ÷ x = -11

- Multiply the divisor by -11

∴ -11(x + 5) = -11x - 55

-Subtract this expression from the new dividend

∴ -11x + 5 - (-11x - 55) = -11x + 5 + 11x + 55 = 60

∴ The quotient is 3x - 11 with remainder = 60

* The quotient is 3x - 11 + 60/(x + 5)

What equation of the line that has a slope of -4 and passes through the point (-2,-5)? Answer ASAP!!
Anna11 [10]

Answer:

<em>Given </em><em>points </em><em>are </em><em>(</em><em> </em><em>-</em><em>2</em><em> </em><em>,</em><em> </em><em>-</em><em>5</em><em> </em><em>)</em><em> </em><em>and </em><em>slope </em><em>(</em><em> </em><em>m</em><em>) </em><em> </em><em>=</em><em> </em><em>-</em><em>4</em>

Step-by-step explanation:

<em>y </em><em>-</em><em> </em><em>y1</em><em> </em><em>=</em><em> </em><em>m </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>x1</em><em>)</em>

<em>y </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>-</em><em>4</em><em> </em><em>(</em><em> </em><em>x </em><em>+</em><em> </em><em>2</em><em> </em><em>)</em>

<em>y </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>-</em><em>4</em><em>x</em><em> </em><em>-</em><em> </em><em>8</em>

<em>4x </em><em>+</em><em> </em><em>y </em><em>+</em><em>5</em><em> </em><em>+</em><em> </em><em>8</em><em> </em><em>=</em><em> </em><em>0</em>

<em>4x </em><em>+</em><em> </em><em>y </em><em>+</em><em>1</em><em>3</em><em> </em><em>=</em><em> </em><em>0</em><em> </em>

<em>y </em><em>=</em><em> </em><em>-</em><em>4</em><em>x</em><em> </em><em>-</em><em> </em><em>1</em><em>3</em>
