Number 1 76
number 2 760,000
number 3 760
Funciton form is f(x)=something
basicallly know that f(x) is the output or y
just solve for y
-3x-6y=0
add 3x to both sides
-6y=3x
divide both sides by -6
y=-1/2x
f(x)=(-1/2)x
The system of inequalities that represents the number of copies that Julissa can print to meet her goal is given by:
- .

<h3>What is a system of inequalities?</h3>
A system of equations is when two or more variables are related, and inequalities are built to find the values of each variable.
The variables are given as follows:
- Variable x: Number of color copies.
- Variable y: Number of gray scale copies.
She needs to print no fewer than 8 copies, hence:
.
It takes 4 minutes to print a color copy and 2 minutes to print a grayscale copy. She has at most 25 minutes, hence:
.

Answer:
length = 8m
width = 4m
Step-by-step explanation:
The perimeter of a rectangle is the formula: P = 2w + 2l, where 'w' is equal to the width and 'l' is equal to the length. In this case, the width can be expressed as 'w' and the length, which is '4 meters longer than its width' would be 'w +4'. So, when you put these expressions into the equation:
P = 2w + 2(w +4)
P = 2w + 2w + 8 or 4w + 8
Since perimeter = 24m, plug it in and solve for 'w':
24 = 4w + 8
Subtract 8 from both sides: 24 - 8 = 4w + 8 - 8 or 16 = 4w
Solve for w: w = 4m
Solve for l: l = w + 4 or 4+4, so l = 8m
