2 \frac{1}{2}+(-2\frac{1}{4})

This is equal to:

2\frac{1}{2}-2\frac{1}{4}

When you add a negative number, it turns into subtraction.

First, I would change it to mixed numbers:

\frac{5}{2}-\frac{9}{4}

Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:

\frac{10}{4}-\frac{9}{4}

Now, you simply subtract:

10-9=1

1/4 is your answer.

I hope this helps :)

The graph below plots a function f(x):
ASHA 777 [7]

Answer:

40 units per sec

Step-by-step explanation:

The average rate of change in this case is the change in y over the first three seconds (which is 220 - 100, or 120) divided by the elapsed time (which is 3 seconds).

                             120

Thus, we have ------------ = 40 units per sec

What is the simplified form of the quantity 4 x squared minus 25 over the quantity 2 x plus 5 ?
Vera_Pavlovna [14]

(4x^2 -25) /( 2x+5)

Factorise the numerator

((2x)^2 - (5)^2 ) / ( 2x+5)

Applying the Difference of squares

= ((2x +5)(2x -5))/ (2x+5)

(2x+5) cancels in both numerator and denominator

That implies ,

= (2x-5) , with restriction 2x+5 not equals to 0

or x not equals to -5/2

So the first one is the correct answer

(2x+5) , restriction , x not equals to -5/2
