Since 3^2 - (-4)(7) must be bigger than 0
Then it has two real roots.
Answers are as follows
B = 51.5
a = 34.6
c = 55.6
Ex. if your problem is 2/3 ÷ 6/1 you would keep the first fraction the same, change division to multiplication and flip the second fraction
2/3×1/6
Hint: KCC (Keep, change, change)
Answer:
Option C, 1225
Step-by-step explanation:
y=4.009x-77.531
selling 325 pizzas, so x=325, now putting the value of x in the equation,
y=4.009×325-77.531
or, y=1225.394
y = 1225.394, which is the profit, if we approximate it to the nearest value, it's $1225
The answer would by 58. I hope this helps!!
