The quadratic equation with roots a and b is given by:

Here a=1/2 and b=-4.
So the equation is given by:

The quadratic equation is as shown above.
Answer:
36
Step-by-step explanation:
x+4y=8+4(7)=8+28=36
Complimentary angles, when added, will equal 90 degrees
so < DFG and < JKL, when added = 90
x + 5 + x - 1 = 90
2x + 4 = 90
2x = 90 - 4
2x = 86
x = 86/2
x = 43
< DFG = x + 5......43 + 5 = 48 degrees <==
< JKL = x - 1........43 - 1 = 42 degrees <==
Answer:
Step-by-step explanation:
1. The length of the fish a fisherman catches, f, must be at least 8 inches for him to keep it.

v<$8,400
4. The number of people, p, that a café can seat at once is no more than 53.
p<_53 people
5. The time, t, a customer has left on a parking meter is at least 13 minutes.
