What is the quotient (2x4 – 3x3 – 3x2 + 7x – 3) ÷ (x2 – 2x + 1)?
Inessa [12570]

Answer:

Quotient: 2x^2+x-3

Refer to the attached document.

Step-by-step explanation:

Provided: (2x^4-3x^3-3x^2+7x-3)\div (x^2-2x+1)

A rational expression is provided, and we need to compute the quotient.

We will utilize long division to obtain the quotient.

Initially, we eliminate 2x^4 by x^2

x^2-2x+1 ) 2x^4-3x^3-3x^2+7x-3 ( 2x^2+x-3

-2x^4+4x^3-2x^2

x^3-5x^2+7x

-x^3+2x^2-x

-3x^2+6x-3

3x^2-6x+3

0

Thus, the result of the division is 2x^2+x-3

Ivan and Tanya share £150 in the ratio 4:1 how much more Ivan has then tanya
Zina [12379]

Hello!

--------------------------------------------------------

Solution:

The ratio is expressed as 4 to 1.

Add these parts together.

4 + 1 equals 5.

Now divide.

150 divided by 5 results in 30.

Next, multiply to find Ivan's share.

30 multiplied by 4 gives us 120.

30 multiplied by 1 equals 30 for Tanya.

Verify.

120 plus 30 totals 150.

Then subtract.

120 minus 30 equals 90.

--------------------------------------------------------

Answer:

Ivan possesses £90 more than Tanya!

--------------------------------------------------------

I hope this has been helpful! Best of luck!

Answer:

A: With each additional procrastination day, the expected grade drops by 3.64 points.

Step-by-step explanation:

The slope of a Regression Line

A linear equation can be expressed in slope-intercept form:

y = mx + b

Here, m represents the slope and b indicates the y-intercept.

The slope reveals the rate and direction of change in the graph as x varies.

<pif m="" is="" positive="" increases="" in="" x="" result="" y.="">

If m is negative, increases in x lead to decreases in y.

<pthe regression="" equation="" is:="">

ŷ = –3.64x + 96.5

Where:

x = number of procrastination days

ŷ = anticipated grade

<pthus the="" slope="" is="" m="-3.64." this="" indicates:="">

A: With each additional procrastination day, the expected grade drops by 3.64 points.
