7 books costs $14, etc. We have points in a line
(7,14)
(8,16)
(9,18)
They're all points on the line y=2x which just means it costs $2 a book. So 1 book costs $2, 2 cost $4, and 3 cost $6. We have three new points:
(1,2)
(2,4)
(3,6)
They're all on the same line, y=2x, just closer to the origin than the first three. We plot a point at x=1, y=2, etc.
Merry Christmas
Answer:
The same thing would happen over and over again.
For 1 you need 4 triangles the same size and for 2 you need to long triangles abs a different one
Answer:
x + 4y ≥ 15; y ≥ 0
Step-by-step explanation:
The solid line signifies it is a ≤ or ≥.
The equation of the line joining 0, 3.75 and 15, 0 is gotten using the formula:
Since the first and second quadrant are shaded, this represents y ≥ 0.
Also, above the solid line of 4y + x = 15 is shaded, this represents 4y + x ≥ 15.
Hence the inequality modeled is x + 4y ≥ 15; y ≥ 0
