2nd equation:
8 x-y=10 ⇒ y= 8 x-10
We will switch that in 1st equation:
8 x-10=x²+12 x+30, or:
x² + 4 x +40 = 0, a=1,B=4, c=40
Discriminant : D= b² - 4 ac= 16 - 160 = -144 and because it is negative there are no real solutions.
Answer: D)
Answer:
C. Zero
Step-by-step explanation:
The solution of the system of equations would be the point where they intersect, but since these lines are parallel, they will never intersect, so therefore there are zero solutions.
Answer:
5
Step-by-step explanation:
This is in the form y = mx + b
M is the slope of the equation which is rise over run
b is the y intercept, which is when x = 0 and the line intercepts the y-axis
