Answer:
Hello, so the answer is 21.
Step-by-step explanation:
Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.
So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.
Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.
Now, 24 minus 3 equals 21. So there we have it :)
Hope I helped!
Answer:
y = -3/2x + 13/2
Step-by-step explanation:
y = -3/2x + b
2 = -3/2(3) + b
2 = -9/2 + b
13/2 = b

STEP-BY-STEP EXPLANATION:
We must bear in mind that when a value increases or decreases in percentage form, the form of the equation is exponential, while when it increases or decreases in a fixed manner, the form of the equation is linear.
Starting from the equation, the equations would then be:
A.
![\begin{gathered} V=10500\cdot(1+9\%)^t \\ V=10500\cdot(1+0.09)^t \\ V=10500\cdot1.09^t \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20V%3D10500%5Ccdot%281%2B9%5C%25%29%5Et%20%5C%5C%20V%3D10500%5Ccdot%281%2B0.09%29%5Et%20%5C%5C%20V%3D10500%5Ccdot1.09%5Et%20%5Cend%7Bgathered%7D)
