Thang decided to borrow $9000 from his local bank to pay for a car. his loan was for 3 years at a simple interest rate of 7%. how much interest will thang pay?

$1,890

Step-by-step explanation:

It is important understand the type problem here. Since it is a interest problem, we need figure out which interest it is and the correct formula.

The question asks a simple interest and the formula is

"I" is is the interest.

"P" is the principal amount.

"r" is the rate.

"t" is the time in years.

Afterwards, we plug in the values into formula. We want to find "."

"" would be the $9000. "" would be the 7%. "" woud be the time in years.

Therefore, Thang will need to pay an interest of $1,890.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
