Answer:
Step-by-step explanation:
- subtract 5 from both sides of the function
- divide 2 from both sides
- then at this point you're supposed to get -5/2
The interest rate is 0.58, or 58 percent.
11,193.64 = 10,000 (1 + i)^2
Divide each side by 10,000.
1.119364 = (1 + i)^2
Take the square root of both sides.
1.058 = 1 + i
Subtract 1
i = 0.58
Product of the numbers is 15
<u>Step-by-step explanation:</u>
Step 1:
Let the numbers be a and b. Given that, the sum of the cubes of the 2 numbers is 152 and the sum of the 2 numbers is 8. Form equations out of the given data.
⇒ a³ + b³ = 152 and a + b = 8
Step 2:
Use identity a³ + b³ = (a + b)³ - 3ab(a + b). Substitute the values in this identity.
⇒ 152 = 8³ - 3ab(8) = 512 - 24ab
⇒ 24ab = 360
⇒ ab = 360/24 = 15
0.03x + 15 y = 0.03x - 15 y = -0.03x + 15 y = -0.03x - 15
