Let L represent the length of the rectangle.

Let W represent the length of the rectangle.

We know that the perimeter of the rectangle is 48cm, which is equal to 2(L + W).

Therefore, L + W = 24cm.

We also know that L = 2W.

Hence, Length = 16cm and Width = 8cm.

$205 + 18% of $205

205+\frac{18}{100}\times 205

=205+0.18\times 205

Write an equation in slope intercept form that passes through the point (3,9) and has a slope of -5
Anna35 [415]

Answer:

y= -5x +24

Step-by-step explanation:

<u>Slope-intercept form</u>

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -5, m= -5.

Substitute m= -5 into the equation:

y= -5x +c

To find the value of c, substitute a pair of coordinates that the line passes through into the equation:

When x= 3, y= 9,

9= -5(3) +c

9= -15 +c

c= 9 +15

c= 24

Thus, the equation of the line is y= -5x +24.
