Plug in 3 for x
f(3) = 2(3) + 1
f(3) = 6 + 1
Solution is 7
The unit price is $0.20 per ounce or $3.20 per pound.
Answer:
y = 2|x+3| -2
Step-by-step explanation:
1) slope = rise/run= 4/2 =2 - for the right line
2) y = 2|x| initial graph
3) It is moved 3 units left
y = 2|x+3|
4) It moved 2 units down
y = 2|x+3| -2
It's a 90 degree rotation since it only moves one quadrant up clockwise
<u>Answer:</u>
$2500
<u>Step-by-step explanation:</u>
We know that 5000 is invested at 3% and we are to find the amount of money which must be invested at 5% such that the total interest after one year is $275.
Supposing x to be the amount of money to be invested, we can use the following equation to solve this problem:
0.03 * 5000 + 0.05x = 275
5x = 27500- 15000
5x = 12500
x = $2500
Therefore, $2500 must be invested.
