Answer:
1. you start with $ 3 and save $1 each month
2. your total savings is 3 times the number of month multiplied by itself
3. you save $3 the first month and then each month the amount triples
Step-by-step explanation:
1.
as y axis represents savings while x axis represents months
the statement "you start with $ 3 and save $1 each month"
is best described by the graph of straight line having slope of 1 and intercept of 3.
2. your total savings is 3 times the number of month multiplied by itself
= 3(x)(x)
= 3x^2
3. as y axis represents savings while x axis represents months
the statement "you save $3 the first month and then each month the amount triples" is best described by the exponential graph starting to rise from point (1,3) which means $3 save at 1 month.

Answer:
Applying the formulae, (a+b)2+(a−b)2=2(a2+b2)
and (a+b)2−(a−b)2=4ab where a=5x;b=2
4×(5x)×22((5x)2+22)=1213
20x25x2+4=1213
On cross multiplying and simplifying,
75x2−65x+12=0
75x2−20x−45x+12=0
5x(15x−4)−3(15x−4)=0
(5x−3)(15x−4)=
x={53,154}={0.6,0.27}
Hence, m=0.6

Ok so if 4x-y=5 then x+y=10 thats the answer
