Which system has a solution of (1,4)? Y = 2x - 2 and y = -3x + 13
5x + y = 9 and 10x - 7y = -18
4x - 3y = 6 and y = -3x + 15
3x + 4y = 18 and -2x + 4y = 8

answer: lol haha i'm in flvs too!

but to answer question number 1 would be a.

and number 2 would be c.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

correct answer is b. 27/8
