So the total amount of paper is 4/4 right?
And she kept 3/4.
So we have to minus 3/4 from 4/4.
Because it has the same denominator we need not change it to similar one.So 4-3 is one.
So answer is 1/4

find an equation of the line passing through the point (-4,-6) that is parellel to the line y=-2/9x-1
ryzh [129]

<em><u>The equation of the line passing through the point (-4,-6) in slope intercept form is:</u></em>

y = \frac{-2}{9}x -\frac{62}{9}

<em><u>Solution:</u></em>

Given that we have to write the equation of the line passing through the point (-4,-6) that is parallel to the line y=-2/9x-1

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---------- eqn 1

Where, "m" is the slope of line and "c" is the y intercept

<em><u>Given equation of line is:</u></em>

y = \frac{-2x}{9} -1

<em><u>On comparing the above equation with eqn 1,</u></em>

m = \frac{-2}{9}

We know that slopes of parallel lines are equal

Thus slope of line parallel to given line is also \frac{-2}{9}

Now find the equation of line with slope \frac{-2}{9} and passing through (-4, -6)

\text{Substitute } m = \frac{-2}{9} \text{ and } (x, y) = (-4, -6) \text{ in eqn 1}\\\\-6=\frac{-2}{9} \times -4+c\\\\-6 = \frac{8}{9}+c\\\\-6 = \frac{8+9c}{9}\\\\-54 = 8+9c\\\\9c = -62\\\\c = \frac{-62}{9}

\text{Substitute } m = \frac{-2}{9} \text{ and } c = \frac{-62}{9} \text{ in eqn 1}\\\\y = \frac{-2}{9}x -\frac{62}{9}

Thus the equation of line is found

Find the HCF of x³y² and x^2<br>​
Elina [12.6K]

Answer:

x^2

Step-by-step explanation:

Hello!

The HCF or the highest common factor (sometimes also known as the greatest common factor, GCF), is the greatest factor between terms.

First, let's expand both terms:

  • x^3y^2 = x*x*x*y*y
  • x^2 = x*x

If we keep them on top of another, we can see that the overlapping variables are x*x, meaning that the greatest common factor between them is x^2.
