A student used synthetic division to divide x^3-3x^2-2x by x+1

Answer:

The Synthetic Division and Remainder theorem is as shown below

Step-by-step explanation:

Given:

Polynomial x^{3} -3x^{2} -2x divided by x+1

Solution:

For Synthetic Division we need to have coefficients,

So  the coefficients are

1, -3, 2, 0

and we have x+1

∴    -1   <u>1   -3  2   0      </u>

           <u>    -1   4   -6      </u>

           1   -4  6  -6

Now the remainder is -6  by synthetic division

In Remainder theorem substitute x=-1 in the polynomial we will get the required remainder.

(-1)^{3} -3(-1)^{2} -2(-1)

∴ = -1 -3-2

∴ = -6

which is same as in synthetic division.

A line passes through (5,-2) with a slope of 1/4. Write the equation in slope-intercept<br> form.
trapecia [35]

Answer: y = \frac{1}{4}x - 3 \frac{1}{4}

Step-by-step explanation:

    Slope-intercept form is in the form of y=<em>m</em>x + <em>b</em> where m is the slope and b is the y-intercept.

    We are given the slope, so we will plug this in.

y = <em>m</em>x + <em>b</em>

y = (\frac{1}{4})x + <em>b</em>

<em />

    Now, we will solve for the y-intercept by plugging in the point they give us.

y = (\frac{1}{4})x + <em>b</em>

(-2) = (\frac{1}{4})(5) + <em>b</em>

-2 = 1.25 + <em>b</em>

-3 \frac{1}{4} = <em>b</em>

<em />

    Lastly, we will plug this variable into the equation we wrote above for our final answer.

y = \frac{1}{4}x - 3 \frac{1}{4}
