Step-by-step explanation:
5q+8p=775
q + p = 125
5q + 8q = 775
-5q -5q = -625
3q = 150
q = 50 premium
q + 50 = 125
q = 75 quick
Answer:
Your solution is (1, -4)
Step-by-step explanation:
The equations both equal <em>y</em>, so you can set them equal to each other.
y = -4x
y = -3x - 1
-4x = -3x - 1
add 3x to both sides
-x = -1
divide both sides by -1 for x to be positive
x = 1
plug x back in
y = -4(1)
y = -4
y = -3(1) - 1
y = -3 - 1
y = -4
Your solution is (1, -4)

Step-by-step explanation:
Even two points are enough to plot a line. Just pick two points (x1,y1), (x2,y2) that satisfy the equation 2y=3x+11, for example x=1,y=7 and x=0,y=5.5.
Then plot them on the plane, and connect the two dots to get your line.
