Answer:
y = 0.5x + 1
Step-by-step explanation:
4 up, 8 right
rise over run
slope = 4/8 or 1/2
y-int = 1
Assuming the spaces mean plus (+):
2(3y+5) = 3(5y+13)
6y+10 = 15y+39
10 = 9y+39
9y = -29
Therefore, y = -29/9 or -3.22
The answer is the first tile on the very left
s = sqrt(227) where "sqrt" is shorthand for "square root"
To get this answer, we basically replace A with 227 and we go from
A = s^2
to
227 = s^2
So if s^2 = 227, then s = sqrt(227) after we apply the square root to both sides. Because s is some length value, it makes no sense to have it negative. Therefore we don't consider the negative version of the square root.
