Answer:

whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:

Step-by-step explanation:

I think the answer to your first question should be:

30a²b - 30ab²

Your second answer is good

whenever you're multiplying terms that have exponents you multiply the coefficients and add their exponents:

for example, 6a²b³c x 2abc = 6(2)(a²)(a)(b³)(b)(c)(c)

= 12a³b⁴c²

Answer & Step-by-step explanation:

3x²

This term represents a monomial expression. Mono- means one. This term is by itself. It has no other term added or subtracted to it.

The coefficient of this term is 3 because it is the number that the variable is connected to.

gregori [183]

Answer:

Step-by-step explanation:

Part A

The function representing the amount of money in account A after x years is represented by the function

f(x) = 9,628(0.92)x

The amount of money in account A is decreasing by 8% per year.

Part B

The table showing the amount g(r), in dollars, of money in account B after r years with number of years given as 1 2 3 4 and amount in dollars) 1,375 1,512.50 1,663.75 1,830.134.

Looking at the table,

The change per year is

(1512.5 - 1375)/1375 = 137.5/1375 = 0.1

The percentage change is 0.1× 100 = 10%

The amount in account B increases by 10%

Therefore, account B recorded a greater percentage change in amount of money over the previous year since the change in account B is 10℅ which is greater than 8% in account B

The correct answer is: x < 1.25

To solve this, we following the same steps as when solving inequalities. We just have to remember to reverse the sign if we multiply or divide by a negative number.

-1.2x - 8.2 > -9.7
-1.2x > -1.5
x < 1.25
