Answer:

The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.

Step-by-step explanation:

1 + 4 = 5

2 + 5 = 12

12 is obtained by adding 2 + 5 = 7 and adding the result obtained in previous result which is 5 to 7

⇒ 7 + 5 = 12

Now, 3 + 6 = 21

21 is obtained by first adding 3 + 6 = 9 and the previous result obtained is 12

So adding 12 to 9 ⇒ 12 + 9 = 21

Hence, The puzzle is first add the current two numbers and then add their sum to result obtained in previous step.

They also add the previous sum....1+4=5 and 5+5+2 is 12....12+6+3 is 21 and so on (:

Answer:

See attachment

Step-by-step explanation:

We can graph this line using the equation given to us. The equation is in slope-intercept form, y=mx+b. In this form, m = slope and b = the y-intercept.

So, we can tell that the slope is -\frac{1}{5} and the y-intercept is (2,0).

We begin by plotting on the graph the y-intercept, (2,0).

The slope also equals the \frac{rise}{run}. The slope is negative, so the line will slope down. From the point we have plotted, we will <em>rise</em> negative 1 unit. This means to move down<em> </em>1 unit. From this point, we will <em>run</em> 5 units. Because the line is negative, we will move 5 units to the left, not the right. We land on point (5,1).

Now, we will draw a line from these two points. This is the line shown in the equation.

Good luck ^^

How do i do x^2 - 10x = -25
Tatiana [17]
Set the single term factor on the left side of the equation equal to 0 0 . x=0 x = 0.
Set each of the factors of the left side of the equation equal to 0 0 . ...
Since −10 - 10 does not contain the variable to solve for, move it to the right side of the equation by adding 10 10 to both sides. ...

Help. What’s the correct answer?
vesna_86 [32]

Answer:

f(g(x)) = -9(sqrt(x + 1) ) + 9

-36

Step-by-step explanation:

This is easier to see if you use the expanded notation.

f(g(x)) = ?

But what that means is that the left most function is f(x) and where every you see an x, you put in a g(x) like so

f(g(x)) = -9(g(x)) + 9    Now substitute the right side of g(x) into the equation for f(x)

f(g(x)) = -9(sqrt(x + 1) ) + 9

Edit to get the numerical answer.

This should be your answer or the expression that will give you the answer.

f(g(24)) = -9(sqrt(24+1) ) + 9

f(g(24)) = -9sqrt(25) +9

f(g(24)) = -  9*5 + 9

f(g(24)) = - 45 + 9

f(g(24)) = - 36
