Answer:
C. -1
Step-by-step explanation:
Find the y intercept by plugging in the slope and a given point into the equation y = mx + b. Then, solve for b:
y = mx + b
-7 = -3(2) + b
-7 = -6 + b
-1 = b
So, the y intercept is -1.
The correct answer is C. -1
Answer:
I am not sure the answer but I can say this from my experiences, to know the shapes and sizes, you may measure like I usually do.
Step-by-step explanation:
I am not sure
Let x be white marbles, y be yellow marbles
x+y=54…(1)
x=3y - 6 …(2)
put (2) into (1)
(3y - 6) + y = 54
4y = 60
y=15
put y=15 into (1)
x + 15=54
x=39
so y=15 x=39
