Answer:
Step-by-step explanation:
A linear equation is an equation with two variables whose graph is a line. ... is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include all points.
Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer

Step-by-step explanation:
add one to all sides
Answer:
Yes
Step-by-step explanation:
Draw a vertical line on the x value of 1/4
It's just a straight line upwards
