Answer:
The answer is C: .19
Step-by-step explanation:
<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7

Answer:
-16
Step-by-step explanation:
In this problem, we are adding a negative integer and a positive integer. From this, we already know that the sum will be negative. (- plus + = -)
Since 20 is positive, you can remove the plus sign so your equation looks like
20 - 36
Next, subtract to get -16

X1 = 4 so sqrt(4) = 2
x2 = 9 so sqrt(9) = 3
3-2 = 1
9-4 = 5
rate of change = 1/5
