Novay_Z [31]

Answer:

Length = 6cm

Step-by-step explanation:

You would get 6cm as the length, because 6 ÷ 3 = 2, that is your width. So in the same way, you would divide 18 by 3 and get 6, thus the length of the second rectangle is 6 centimeters

Hope it helps :D

Find an equation of the line passing through the pair of points. Write the equation in the form Ax+By=C
Igoryamba

Answer:

<h2>11x - y = -79</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

We have the points (-7, 2) and (-8, -9). Substitute:

m=\dfrac{-9-2}{-8-(-7)}=\dfrac{-11}{-1}=11

y-2=11(x-(-7))\\\\y-2=11(x+7)

Convert to the standard form:

y-2=11(x+7)           <em>use the distributive property </em>a(b + c) = ab + ac

y-2=11x+77            <em>add 2 to both sides</em>

y=11x+79           <em>subtract 11x from both sides</em>

-11x+y=79        <em>change the signs</em>

11x-y=-79
