I think the answer for this is C
Answer:
There are 180 milligrams of gold in the alloy
Step-by-step explanation:
because i know
We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.
the point slope equation of a line is y - y1 = m (x - x1)
plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8
B. The equation can become -2(4x-1)=12 by applying the addition property of equality.
