The largest square you can make using 40 tiles, would be 100
Answer:
infinitely many solutions
Step-by-step explanation:
solve by substitution:
solve equation 1 for y: - y = 7 - 4x; divide by -1 to simplify into y = -7 + 4x
Substitute - 7 + 4x into the second equation to obtain:
3(-7 + 4x) - 12x = -21, which yields:
-21 + 12x - 12x = -21, which simplifies 0 = 0
a result of 0 = 0 means infinite solutions such as:
(2,1), (3, 5), (4, 9), (5, 13), (6, 17)....

Answer:
Step-by-step explanation:
B is the answer
Answer:
y = -6x + 42
Step-by-step explanation:
Slope (m) =(y2-y1)/(x2-x2) = -6/1 = -6
b=42
