Can someone please help me

Answer:

the graph of the function is non-linear

the table can be represented by the equation y=4x+4

Step-by-step explanation:

non linear because 1+7=8 and then 10+2 = 12 so they have different numbers to add each time

represented by the equation because the x numbers (1,2,3,4,) all multiplied by 4 and added by 4 gives you y

any more help just ask :)

What is the answer to 2x+4y=16:4y=12

allsm [11]

Answer:

Here,

$2x + 4y = 16....eqn \: i \\ 4y = 12....eqn \: ii$

substituting the value of 4y in eqn i fron eqn ii

so eqn i becomes

$2x + 12 = 16 \\ 2x = 4 \\ x = 2$

$y = 12 \div 4 = 3$

Thus,

$x = 2 \: and \: y = 3$

...hope this helps:)
