The quadratic clearly has two real zeros, two places where it crosses the x axis. That corresponds to a positive discriminant.
Answer: positive
Answer:
None.
Step-by-step explanation:
The equation 3=5 is false, therefore, there are no solutions.
3≠5
Answer:
c = 8x-30
23x-90
Step-by-step explanation:
Since the cost of soda is x, 8 times the cost of soda is is 8x.
Then, you have to take 30 cents away, so the cost for pizza would be 8x-30 or 8x-.30.
This is your pizza or c.
Next, to put in 3 pizzas and 5 sodas, you just multiply 3 and 5 by the corresponding variables.
So 3(8x-30) + 5(x) = 18x - 90 + 5x = 23x - 90 or 23x - .90
Answer:
square root of 26 (sorry couldn't get the symbol)
Step-by-step explanation:
C^2 = A^2 + B^2 (Pythagoras Theorem)
C^2 = 5^2 + 1^2
C^2 = 26
take square root of both sides
C =
The answer would be 10. Im not quite sure if thats the answer, im sorry if i get it wrong. Otherwise i hope this helped you! :)
