Recall your d = rt, distance = rate * time
now, if say, by the time they meet, Mr Cunningham has travelled "d" miles, that means Mrs Cunningham must also had travelled "d" miles as well.
However, he left 3 hours earlier, so by the time he travelled "d" miles, and took say "t" hours, for her it took 3 hour less, because she started driving 3 hours later, so, she's been on the road 3 hours less than Mr Cunningham, so by the time they meet, Mrs Cunningham has travelled then "t - 3" hours.
Answer:
x=-8 x=2
Step-by-step explanation:
x^2 +6x-6 = 10
Subtract 10 from each side
x^2 +6x-6-10 = 10-10
x^2 +6x-16 = 0
Factor
What 2 numbers multiply to -16 and add to +6
8*-2 = 16
8-2 =6
(x+8) (x-2) =0
Using the zero product property
x+8 = 0 x-2 =0
x=-8 x=2
Given:
The given system of equations is:
To find:
The solution to this system of equations by graphing.
Solution:
We have,
The table of values for first equation is:
x y
0 1
1 -1
Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.
The table of values for second equation is:
x y
0 -4
2 -3
Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.
The graphs of given equations are shown in the below figure.
From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).
Therefore, the solution to this system of equations is:
x-coordinate: 2
y-coordinate: -3
28 appointments can be scheduled each week if each customer must be trimmed and styled
<em><u>Solution:</u></em>
From given,
<em><u>Therefore, total time taken for each customer hair to be trimmed and styled is:</u></em>
Thus, each customer trim and style = 25 minutes
Given that,
The hairstylist plans to work 2 1/3 hours each day for 5 days each week
Then, for 5 days, the hairstyist will work for:
Thus hairstylist will work for 700 minutes each week
<em><u>Total number of appointments:</u></em>
Total number of appointments for each week is found by dividing the working time of hair stylist for each week divided by time spent for each customer for trim and styled
Thus 28 appointments can be made
