The correct answer is y + 2 = -2(x-5). 

Original Equation: y = -2x + 8

Test Option B:

y + 2 = -2(x-5)

   y + 2 = -2x + 10
       - 2             - 2
-----------------------------
   y = -2x + 8

Answer:


Step-by-step explanation:

In the first part the given polynomial is 3x^{3}-2x^{2}+x-1, we have to divide this polynomial by (x-1) using synthetic division.

Here are the steps of synthetic division

Step 1: Set up the synthetic division table in which the coefficients are written in descending power of x.

Step 2: Drop down the leading coefficient i.e the coefficient of highest power of x to the bottom row.

Step 3:  Multiply a by the value just written on the bottom row and write this value just down of the number written next of leading coefficient.  Here, a is 1(taken from divisor)

Step 4:  Add the column made in step 3.  Repeat these steps until the last column reached.

In the second part,

It is given that divisor polynomial is the factor of given polynomial then we have to tell the remainder which is 0 because if divisor polynomial is the factor the it will completely divide the given polynomial which gives remainder 0.

In the third part,

Given when one uses the synthetic division to divide by (x-3) then what number is used to multiply each term that is dropped down or added.

As explained the steps of synthetic division in first part

x-3=0 ⇒ x=3 which is a

In step 3, Multiply a by the value just written on the bottom row and write this value just down of the number written next of leading coefficient. So, 3 is multiplied.

As explained in Step 2: Drop down the leading coefficient i.e the coefficient of highest power of x to the bottom row.

The columns which is formed by above steps are added.

Example on how you will use statistics and probability in real life situations as a student
LUCKY_DIMON [66]

Answer:

weather forecasting, health insurances

Step-by-step explanation:

probability is used by weather forecasters to assess how likely it is that there will be rain, snow, clouds, storms, etc. on a given day in a certain area. health insurance also uses statistics and probability to determine how likely it is that certain people will spend a certain amount on healthcare each year.

Using the quadratic formula to solve 11x^2-4x=1, what are the values of X?
Rashid [163]
The correct answers for x would be \frac{2 +/-  \sqrt{15} }{11}.

In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following. 

11x^{2} - 4x - 1 = 0

Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below. 

\frac{-b +/-  \sqrt{ b^{2} - 4ac} }{2a}

Now we can plug the values into the equation to solve. 

\frac{4 +/- \sqrt{ -4^{2} - 4(11)(-1)} }{2(11)}

Then simplify using the order of operations. 

 \frac{2 +/- \sqrt{15} }{11}.
