Answer:
length of each plan A work out: 1 hour
length of plan B work out: hours
Step-by-step explanation:
Let x represents the time taken to do plan A
y represents the time taken to do plan B
On Monday there were 5 clients who did Plan A and 2 who did Plan B.
Miguel trained his Monday clients for a total of 6 hours
5x + 2y = 6 -----------> equation 1
On Tuesday there were 3 clients who did Plan A and 8 who did Plan B. .He trained his Tuesday clients for a total of 7 hours
3x + 8y = 7 -------------------> equation 2
Now we solve for x and y
Let multiply the first equation by -4 to eliminate y
-20x -8y = -24
3x + 8y = 7
------------------------ (add both equations)
-17x = -17
Divide both sides by -17
So x= 1
Plug in 1 for x in first equation and solve for y
5x + 2y = 6
5(1) + 2y = 6
5 + 2y =6
Subtract 5 on both sides
2y = 1
y = 1/2
length of each plan A work out: 1 hour
length of plan B work out: hours

Answer:
Option A is correct.
General form of the equation of the line: y-2 = 0
Step-by-step explanation:
The general form of the equation is given by:
y = mx +b where m is the slope and b is the y-intercept.
y-intercepts of the line is the value of y at the point where the line crosses the y-axis(i.e x= 0)
From the given figure;
we can see that the line crosses the y-axis at y =2 and also here the slope is , m= 0
therefore, by definition of y-intercepts
y-intercept (b) = 2
Therefore, the equation of line as shoen in figure is:
y = (0)x + 2
or
y = 2
y-2 = 0
Therefore, the general form of the equation line as shown in the figure is:
y-2 =0
