So you are given a recursive series, which is an equation that writes itself. Now we want to create a explicit rule. Explicit rule is a pattern that uses our first term and add our common difference. So it gives us our first term. $a_{1} = -3$

Lets find the second term of the recursive series.

a_2 = -3 +7 = 4

So it is increasing by 7

So our explicit rule is:

a_n = -3 + 7(n-1)

The limit (as 'x' approaches zero) of x²/(2x+1) is

0 / (0+1) = 0 .

You get this by substituting the limit in place of 'x'.

Sometimes that doesn't work. Sometimes it gives you
monstrosities like 0/0, or 1/0, or ∞/∞ .

But it works for this one. There's nothing wrong with 0/1 = zero .

Suppose that the minimum score on certification test is 200 and the maximum score is 1000. Write an absolute value equation that

vitfil [10]

Answer:

| x - 600 | = 400

Step-by-step explanation:

Absolute value equation of the form:

| x - a | = b

can be solved by:

x - a = b

x = a + b

and

x - a = -b

x = a - b

We can write the inequality | x - 600 | = 400

Let's solve and see if we get values of 200 and 1000:

x - 600 = 400

x = 1000

and

x - 600 = -400

x = 200

So this equation is right.

| x - 600 | = 400

Graph the linear function.<br> f(x)=x+2<br> HELP PLEASE

Serggg [28]

Hey there!

Graphing this will be similar to graphing slope intercept equations (y=mx+b).

As you can see, we have a slope of 1 and a y-intercept of two when you look at the equation and match it up with the slope intercept form Let's look at each answer option and see which one fits.

--------------------------------------------------------------------------------------------

GRAPH A

Graph A does have a y-intercept of two. This means that the line crosses the y-axis at two units up from the origin. However, it has a negative slope because it is going downwards rather than upwards. The slope of our function is positive, so Graph A does not match.

--------------------------------------------------------------------------------------------

GRAPH B

Graph B does have a positive slope of one (a slope of one means that it goes diagonally across every small square on the grid), but it's y-intercept is -2 because it hits the y-axis at 2 down from the origin. Therefore, Graph B does not match this function.

--------------------------------------------------------------------------------------------

GRAPH C

Graph C both goes downward (negative slope) and it hits the y-axis at -2 instead of 2 (wrong y-intercept). Therefore, Graph C does not match the function.

--------------------------------------------------------------------------------------------

GRAPH D

Graph D has a y-intercept of 2 and it has a positive slope of one! Therefore, Graph D does match this function.

--------------------------------------------------------------------------------------------

The correct answer is Graph D.

I hope that this helps! Have a wonderful day!
