Find the slope:
(-19 - 11) / (-8 - 2) = (-30/-10) = 3
Find the y intercept:
y = mx + b
11 = 3(2) + b
b= 5
So equation is:
y = 3x + 5
Answer:
B
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = 80 x b
total cost = 520
the profit has to be at least $1240
80 x 22 = 1760
1760 - 520 = 1240
b is correct
Answer:
Step-by-step explanation:
Move all terms to one side
4x^2 + 4x + 5 = 0
Plug into quadratic formula
x = (-4 <u>+</u> 
) / 2(4)
= (-4 <u>+</u> 
)/8
At this point, there are no real answers. The roots to this equation are complex.
x = (-4 <u>+</u> 8i)/8
= (-1 <u>+</u> 2i)/2
