Number 19 I think is if you add the awnser to one of the numbers you where subtracting and you get the other number you where subtracting you are right like...
Lets say you had the problem 3-2 which is obviously 1 but if you did 2+1 it's 3 so that's how you check.
Answer:
what can i help u with
Step-by-step explanation:
The graph of x = |y| is as shown in the figure.
When we draw a vertical line, it intersects the graph at two points.
This means for the same value of x , we have two values of y.
Or in other words, for the same pre image, we have two images.
Hence it is not a function.
But for every value of x, we do have a value of y, hence it is a relation.
x = |y| is a relation but it is not a function

Answer:
£775
Step-by-step explanation:
From the question, it was given that:
Weekly pay = basic pay + number of houses rented x bonus
This expression can be used to determine the amount of money being paid to the agent every week.
When basic pay = £400, bonus = £75, and the number of house rented = 5.
Then,
Weekly pay = 400 + 5(75)
= 400 + 375
= 775
Weekly pay = £775
The amount of money paid to Mrs Lewis every week is £775.
Answer:
Distance between B and C =
Step-by-step explanation:
Let the time taken to reach from station A to B be x hr
Let the time taken to reach from station B to C be y hr
Given total time from station A to C be 6 hr
∴ x + y = 6
⇒ y = 6 - x → (1)
Also total distance given is 285 miles
As
∴ distance travelled between station A and B
=
distance travelled between station B and station C
=
So, 40x + 55y = 285
⇒ 40x + 55(6 -x) = 285 (From 1)
=> 40x + 330 - 55x = 285
=> -15x = 285 - 330
=> -15x = -45 ⇒ x=3
gives y = 6-3 = 3 hours
Distance between B and C =
