You are investing $2,000 fro 3 months and the APR is 4% so you will get one quarter of the APR for a year. For the year 4% interest is $2,00 x .04 or $80 for the year. # months is 1/4 of a year so divide $80 by 4 to get the interest fro 3 months which is 20 so the answer is B.
Answer: 14
<u>Step-by-step explanation:</u>
f(x) = 3x + 2
To find f⁻¹, swap the x's and y's and solve for y --> Note: f(x) is y
x = 3y + 2
x - 2 = 3y
f(f⁻¹(14)) = f(4)
f(4) = 3(4) + 2
= 12 + 2
= 14
NOTE: the simplified version is .... f and f⁻¹ cancel out, leaving you with 14
20 - 4x = 2(4 - 8x)
Make sure to do the parentheses first or factor out first
20 - 4x = 8 - 16x
add 16x to both sides
20 + 12x = 8
Subtract 20
12x = -12
Divide by 8
x = -1
Answer:
Unit rate is $7 per pound.
6 pounds will cost $42
You can buy 10 pounds for $70
Step-by-step explanation:
28/4 = $7 --> Unit rate is $7 per pound.
