The same way you add and subtract any pair of fractions. You need to make sure the denominators are equal. Once they are equal, you can add or subtract the numerators and place the result over the common denominators.

what is the equation of the line, in slope-intercept form, that contains the points (−1, 2) and (2, −1)?

Ierofanga [76]

$The\ slope-intercept\ form:y=mx+b\\\\The\ slope-point\ form:y-y_1=m(x-x_1)\\\\The\ slope:m=\dfrac{y_2-y_1}{x_2-x_1}\\---------------------\\(-1;\ 2);\ (2;-1)\\\\m=\dfrac{-1-2}{2-(-1)}=\dfrac{-3}{3}=-1\\\\y-(-1)=-1(x-2)\\y+1=-x+2\ \ \ |subtract\ 1\ from\ both\ sides\\\boxed{y=-x+1}$

aleksley [76]

Answer:

The length of the yard is $48\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of the yard required to be fenced is equal to

$P=(5x+8)+2(3x-1)+2(x-2)\\P=13x+2$

$P=106\ ft$

so

$106=13x+2$

solve for x

$13x=106-2$

$13x=104$

$x=104/13=8\ ft$

Find the length of the yard

$5x+8=5(8)+8=48\ ft$
