Hey buddy, here is your answer. Hope it helps u.

Step-by-step explanation:

Without adding we can find out the sum. We just need to count how many numbers are there. In this case there are 9. Then we need to sqau the number. So 9 square=81. So without adding the sum the answer is 81.

Can anyone please help me determine the slope of the line in the graph.
juin [17]

Answer:

slope = 2

Step-by-step explanation:

To find the slope, we need to read 2 points off the graph.

Where the line crosses the y-axis, the point is (0, 2.5).

The next point up on the line looks like (1, 4.5).

slope = m = (difference in y)/(difference in x)

To find the difference in y and difference in x, subtract the y-coordinates and the x-coordinates, respectively, in the same order.

difference in y = 4.5 - 2.5 = 2

difference in x = 1 - 0

slope = m = (difference in y)/(difference in x) = 2/1 = 2

I just don't know it
denis23 [38]
Looking at the question. you'll know that it's a subtraction question so that eliminates C and D. Now look at A and B. It says that 33 stamps were used. So that means the answer is not a negative expression. (B) Is Eliminated.

Consider a function <img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B%281%20-%20x%29%5E2%7D%7B%281%20%2B%20x%29%5E2%
SCORPION-xisa [38]

Answer:

f=

x2−2x+1

x3+2x2+x

Step-by-step explanation:

Let's solve for f.

fx=

(1−x)2

(1+x)2

Step 1: Multiply both sides by x^2+2x+1.

fx3+2fx2+fx=x2−2x+1

Step 2: Factor out variable f.

f(x3+2x2+x)=x2−2x+1

Step 3: Divide both sides by x^3+2x^2+x.

f(x3+2x2+x)

x3+2x2+x

=

x2−2x+1

x3+2x2+x

f=

x2−2x+1

x3+2x2+x
