If y = 9x - 7, which of the following sets represents possible inputs and outputs of the
function, represented as ordered pairs?
{(7,9), (8, 10), (9, 11)}
{(0, -7), (1, 2), (-1, -16)}
{(1,9), (2,7), (3, 16)}
{(-7,0), (2, 1), (-16, -1)}
The answer is b {(0,-7), (1,2), (-1,-16)}
$1 = 2 weeks
-
<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks
-
Answer: You need <u>1600 weeks </u>to get $800
The amount after 3 years would be $221.74
<u>Explanation:</u>
Given:
Principal, P = $200
Rate of interest, r = 3.5%
Time, t = 3 years
Amount, A = ?
We know:

Substituting the value we get:

Therefore, the amount after 3 years would be $221.74
X=2.6
Solution
5x=10+3
5x=13
(divide 5 by both sides)
5x/5=13/5
x=2.6
hope this helps
