Solve the following:
a
4x - 3 = 2x + 7
what does x equal

x=5

Step-by-step explanation:

So we have to combine like terms

4x-3=2x+7

-2x  -2x

2x-3=7

   +3 +3

And now simplify

2x=10

/2   /2

x=5

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
