Hello!
"Standard form" looks like Ax + By = C.
Start by carrying out the indicated multiplication:
y + 9=-3(x-2) becomes y + 9 = -3x + 6
We want to group the x and y terms on the left and the constants on the right. Achieve this by adding 3x to both sides, obtaining: 3x + y + 9 = 6. Next, subtract 9 from both sides: 3x + y = -3.
The given equation, in standard form, is 3x + y = -3.
Answer:
The price increases by 5439 dollars.
The price of the next model is 42439 dollars.
Step-by-step explanation:
The next model of sports car will cost 14.7% more so it will be 114.7% of the current model. Therefore you multiply
37000 * 1.147 = 42439
To find out how much it increases by, you find the difference between the two prices which is 5439 dollars.
Hope this helped!!

Answer:
- 1364
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
4
← is an n th term
with a = 4 and r = - 2
The sum to n terms of a geometric series is
=
, thus
= 
= 
= 
= 
= - 1364
