Answer:
x = -1
Step-by-step explanation:
y = 5 is a horizontal line
It's perpendicular would be a vertical line of the form:
x = a
Since it passes through (-1,-3)
a = -1
Hence line is: x = -1
Answer:

Step-by-step explanation:
First of all we need to know the relation between 1 dollar and 1 cent in order to express everything in the units required in the question.
We know that
, so the amount paid for the item with single dollars has to be multiplied by 100 to express its value in cents.

Now that we have everything in cents, we can make the subtraction:

Replacing the value in cents we get:

Answer:
Let me take 2,3,3 be 2x, 3x, 3x
Colin = 2x
Natasha = 3x
Angad = 3x
The equation forms to find out the value of x
2x + 3x + 3x = 48
=> 8x = 48
=> x = 48/8
=> x = 6
So share of Colin = 2x = £(2×6) = £12
Share of Natasha = 3x = £(3×6) = £18
share of Angad = 3x = £(3×6) = £18
For proof
£12 + £18 + £18 = £48
Hope it helps
