The length of the rectangle is 8cm longer than the width.

masya89 [10]

The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2

to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w

l=w+8=10.5+8=18.5

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.

andreev551 [17]

Answer:

$f(x) = 6x -12$

Step-by-step explanation:

We must write the function of the line in the form $f (x) = mx + b$

First calculate the slope m

$m =\frac{y_2-y_1}{x_2-x_1}$

$y_2 = 18\\y_1 =6\\x_2=5\\x_1=3$

$m= \frac{18-6}{5-3} = 6$

Then

$f(x) = 6x +b$

To have b replaced a point in the function

$f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12$

Finally the function is

$f(x) = 6x -12$
