What is the x value of 2x+3y=18 and x+7y=31

the first question is 9 -3/2y and the second one is 31 - 7y

Step-by-step explanation:

on the first one you move the variable to the right and divide by 2 and on the second one you can only move the variable to the right because you don’t know x to solve the entire equation! hope this helps

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
