Asystem of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation? O y = 4x + 5
O y = 4x - 5
O 2y = 8x - 10
O-2y = -8x - 10

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =    

hope this you and

step-by-step explanation:

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

y - 25 = 2 ( x - 10 ) should be the answer

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
