Answer:

5+k.

Step-by-step explanation:

As you can see in the image I made the example with n=6. In general, if the interval is divided into n equal parts we have that te right value of x in the kth rectangle (Rk) is

Rk = 2+ (1/2)k

So, f(Rk) = f(2+(1/2)k) = 2(2+(1/2)k)+1 = 4+k+1 = 5+k.

By "<span>f(x = 2x + 1" you likely meant "f(x) = 2x + 1."

The given interval is [2,5], and so the width of each interval is (5-2)/n, or (3/n). Since we are using right end points, the x value at the right endpoint of the kth rectangle is 2+k(3/n).  Examples:  if k=1, the value at the right endpoint is 2+1(3/n); if k=2, 2+2(3/n), and so on.  If k=n, then the value at the right endpoint is 2+n(3/n), or 2+3=5, which agrees with the given interval [2,5].

Once again, the given function is f(x) = 2x + 1.
At x = 2+k(3/n), the value of the function is 2[2+k(3/n)] + 1 (Answer).  Check:  If k=n, x = 2 + n(3/n) = 2+3 + 5, and f(5)=2(5) + 1 = 11.</span>

For the graph shown, select the statement that best represents the given system of equations. 3y – x = 2 9y – 3x = 6
poizon [28]
You can find that out by first putting two equations in slope-intercept form y=mx+b by solving for y.
3y - x = 2
3y = x+2
y = (1/3)x + 2/3

9y = 3x + 6
y = (3/9)x + 6/9
y = (1/3)x + 2/3

They are the same line as you can see in the final step.
Since the two lines are the same line, (they "coincide") they are coincident.
Coincident means there are an infinite number of solutions, and since they are the same line, there are an infinite number of solutions.

Need help with this questsion answer as a dollar amount
makkiz [27]

Answer:

100,000,000,000

Step-by-step explanation:

10^6 = 1,000,000. So one million computer programmers.

They're all making 10^5. So 100,000.

1,000,000 * 100,000, since every single one is making 100k.

Therefore, $100,000,000,000 is your answer.

Remember not to include the dollar sign!
