Step-by-step explanation:
From image we get a graphical representation of the second-order polynomial
, where
is related to the horizontal axis of the Cartesian plane, whereas
is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:
a) 
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:
,
b) 
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

Answer:
16 minutes
Step-by-step explanation:
Tom walks for 5 minutes longer than he rides. To figure out the answer, start by subtracting 5:
27 - 5 = 22
Now that you have done this, divide 22 by 2:
22/2 = 11
Now you know that he rode the bus for 11 minutes, and you can add five to the other 11 minutes to know how long he walked:
11 + 5 = 16.

Step-by-step explanation:
Step-by-step explanation:
5:28^25 I think
6:keep the base multiply exponents
7:no because you would multiply the bases and keep the exponent the same
8:7 because 7 x 5= 35
1: 2 and 3 for the second part of it 2 and 5
2:7^30
3:54^3
4:Yes they are just flipped

Answer: 100 miles
Step-by-step explanation: How much time does the bird spend in flight? If you represent the problem in terms of the amount of time the bird is flying, then a solution is fairly straightforward. The two trains are 50 miles apart, and are approaching each other at a relative speed of 50 mph (25 + 25), so it will take one hour for them to meet. If the bird spends one hour flying at 100 mph, then it will traverse 100 miles before the trains meet.
