Answer:
y=2/3
y=4
x=1
Step-by-step explanation:
y=2/3
y=x+3
x= -2x+3
x+2x=3
3x=3
x=3/3
x=1
Answer:
length = 63 ft; width = 10.5 ft
Step-by-step explanation:
Let the width be x.
The length is 6 times the width, so the length is 6x.
The perimeter is the sum of 2 lengths and 2 widths.
6x + 6x + x + x
The perimeter equals 147 ft.
6x + 6x + x + x = 147
14x = 147
x = 10.5
The width is 10.5 ft.
The length is 6x, so the length is 6 * 10.5 ft = 63 ft
The linear inequalities that will limit the solution region in a linear programming problem are called the origin.
<u>Explanation</u>:
- The x-axis is a horizontal line, and it is perpendicular to the y-axis. The origin is called the convergence of the two axes. This property allows multiplying a term or terms into a polynomial.
- The origin is a starting point, and in mathematics, the origin can also be said as the starting point.
- The co-ordinates for every other point are based on how far from the origin that point is. x and y are equal to zero at the origin and cross the x-axis and y-axis.
