Answer:
(x) = x + 2
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = x - 2 ( add 2 to both sides )
y + 2 = x
Change y back into terms of x, thus
x = y + 2, so
(x) = x + 2
Answer:
2 and 8
Step-by-step explanation:
there on opposite sides and are exterior
We know that the longest side of the triangle cannot be longer or equal to the legnth of the sum of the other two sides ( becasue if it was equal, then you would get a straight line)
so if you assume that 12 is longest side then the other sides could be 6
if you assume that the longest side is the third side then the longest side could be 18
Answer:
The consultant sold 15 circular stones and 22 rectangular ones
Step-by-step explanation:
let quantity of circular stones be X , rectangular ones be Y
thus:,We can deduce that,
26x+34y=1138...... equation 1
He sold total of 37 ,both stones
x+y=37... equation 2
Solving simultaneously
make Y subject of the formula in equation 1
34y=1138-26x
