Answer: The value of y is 2
Step-by-step explanation:
If y=5-3 and 3x-y=-1
Take y=5-3 first
y = 5 - 3
y = 2
Then, take 3x-y=-1, and put y = 2 in the Expression
3x-y=-1
3x - (2) = -1
3x - 2 = -1
3x = -1 + (-2)
3x = -1 -2
3x = -3
To get x, divide both sides by 3
3x/3 = -3/3
x = -1
Thus, the value of y is 2 while x is -1
Answer:
The other one (number2) is not a function, because if you plot those points in a graph and use the line rule it shows that more than one point is aligned in that line.
Step-by-step explanation:
0.55 pence or quid per 25 centimeters as if you multiply it by 4 it would be 2.20 pound because 1 metre is 100 centimeters after i divide 100 by 25 i get 4 which would be 1/4 which i would then multiply 1/4 x 2.2 pound
