Alright...so the coordinates of an ordered pair have opposite signs [one sign is positive while the other is negative] so we could have an example of (-x,+y) or (+x,-y) ...that means out of the 4 quadrants these points could be in the 2nd quadrant or the 4th quadrant or corners of the graph
Answer:
1.445×10*3
Step-by-step explanation:
1) 5x-1=x+115
5x-x=115+1
4x=116
x=116/4
x=29 (Answer)
2) 3+5q=9+4q
5q-4q=9-3
q=6 (Answer)
3) 2b+4=-18-9b
2b+9b=-18-4
11b=-22
b=-22/11
b=-2 (Answer)
Hope this helps
Option A). 7, -4 and 1/3
To find the zeros you can factor the polynolial into (3x-1)((x+4)(x-7)
Then:
3x -1 =0 => x = 1/3
x+4=0 => x = -4
x-7 =0 => x =7
Those are the three zeros.
Answer:
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Total distance of the trip = 750 miles
Time of the trip = 12 hours
Speed of Kathy = 65 mph
Speed of Brian = 55 mph
2. For what length of the time did Kathy and Brian drive?
Let's solve the problem, this way:
x = Time in hours Kathy drove
12 - x = Time in hours Brian drove
Now, let's write our equation to solve for x:
65x + 55 (12 - x) = 750
65x + 660 - 55x = 750
10x = 750 - 660
10x = 90
x = 90/10
x = 9 ⇒ 12 - x = 3
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
