I got 460.
Step-by-step explanation:
You multiply 115 by 4. Right?
Answer:
5x + (- 1)
Step-by-step explanation:
So the terms are 2x, -5, 3x, and +4.
2x and 3x have x in common so they can be combined to create 5x.
-5 and +4 don't have variables, so they are also common and can be combined to make -1.
Margot could pickle 500 cucumbers in 2 hours.
She got tired and reduced her rate by one half.
=> 250 cucumber in 2 hours
Let's solve how long would it take her to pickle 2000 cucumbers at thenew rate.
=> 2000 / 250 = 8 times 2 hours
=> it will take her 16 hours to do so.
Constant of proportionality is given by: y=kx oy 
So lets suppose y = 50 and x = 5 so k will be 
This 10 will remain constant. For every $50 Michael saves $5, for $100 he will save $10 , for $150 he will save $15 and so on.
So this 'k' will be same for each value of x and y.
Answer:
A. 0
Step-by-step explanation:
The value of the discriminant is ...
b² -4ac = (-3)² -4(1)(4) = 9 - 16 = -7
The negative discriminant means the roots will be complex.
There are 0 real solutions.
