Answer:
-54
Step-by-step explanation:
8a + 7b + c = 9
We want -6c, but we have c in the equation so multiply by -6
-6(8a + 7b + c) = 9*-6
-48a -42b -6c = -54
Rearranging the equation
-6c - 48a - 42b = -54
Using complementary events, considering a 
probability of drawing a red marble, the probability of not drawing a red marble is of 
.
<h3>What are complementary events?</h3>
They are mutually exclusive events which have the sum of their probabilities as 1.
In this problem, we consider that there is a probability of drawing a red marble, and since drawing a red marble and drawing a non-red marble are complementary events, we have that:
The probability of not drawing a red marble is of .

y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
