3x+y=19
y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:
19-3x=x+3
19-4x=3
-4x=-16
x=4, and since y=x+3
y=7 so the solution is the point:
(4,7)
Answer:
The following are the answers:
a = 1
b = 6
c = -55
Step-by-step explanation:
When looking for a, b, and c in a quadratic, you are looking at coefficients only. The coefficient of x^2, which in this case is 1, is a. The coefficient of x, which in this case is 6, is b. Lastly, the constant at the end, which in this case is -55, is c.
