<h3>F(x) = - 5(x+1+3)</h3>
or, - 12= - 5x-5-15
or, - 12= - 5x-20
or, - 12+20= - 5x
or, 8= - 5x
or, x= 8÷-5
Also,
F(x)= - 5(x+1+3)
or, f(8÷-5)= - 5(8÷-5+1+3)
= - 5(8-5-15÷-5)
= - 5×-12÷-5
= - 12 #
I think this is the answer, though you might need to recheck it
Answer:
In the coordinate form the first no is always the abcissa(x coordinate) and the 2nd value is ordinate (y coordinate)
Answer:
Step-by-step explanation:
Given the perimeter of a rectangle P = 80 inches
Let 'x' be the width of a rectangle.
i.e.
x = width
As the length of a rectangle is three times its width. Thus,
length = 3x
We know that perimeter is the sum of all the sides (width and length) of a rectangle. So,
The Perimeter of a rectangle = 2(width + length)
substituting P = 80, width = x, length = 3x
80 = 2(x + 3x)
80 = 2x + 6x
80 = 8x
divide both sides by 8
80/8 = 8x/8
10 = x
Thus, the value of x = 10
Therefore,
The width = x = 10 inches
The length = 3x = 3(10) = 30 inches
Thus,
