Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
<h3>What is an exponential function?</h3>
It is modeled by:

In which:
- a is the initial value, that is, y when x = 0.
- b is the rate of change, as a decimal.
Function 1 is given by:

Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:

Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

Answer:
It's 27 bags your teacher just dum
Step-by-step explanation:
Answer:
7x-2 = 12x-22
-7x
-2=5x-22
+22
20=5x
÷5
x=4
KL is 7x-2, so substitute the value of x.
7 x 4 - 2 = 26
KL = 26

Answer:
X^2y+x^2z+y^2+yz
Step-by-step explanation:
x^2(y+z)+y(y+z)
x^2y+x^2z+y^2+yz
basically you distrinbute the first bracket to the second bracket
