we have that
using a graph tool
see the attached figure
the solution is the interval [18,22]
Answer:
The desired equation is y = 3x + 2
Step-by-step explanation:
A NEW LINE parallel to y = 3x + 3 has an equation that is identical to y = 3x + 3 except that the y-intercept will be different.
Start with y = 3x + 3; replace x with -1 and y with -1 (which come from the given point): -1 = 3(-1) + b. Then -1 = -3 + b, and b must be +2.
The desired equation is y = 3x + 2.

Answer: E. (126 + 10.5x) square feet
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
The length of a living room is 12 feet and its width is 10 1/2 feet. If the length of the room is being expanded by x feet, then the new length would be (12 + x) feet
Therefore, an expression to represent the new area of the living room in square feet would be
10.5(12 + x)
The expanded form of the expression would be
(126 + 10.5x) square feet
