Answer:
y = (3/2)x + 7
Step-by-step explanation:
(−4, 1) and (−2, 4)
slope m = rise/run = (4-1)/(-2-(-4)) = 3/2
Slope intercept form is y=mx+b
where m=slope, b = y-inercept
y = (3/2)x + b
Use one of the given points for (x,y) to find b
1 = (3/2)(-4) + b
1 = -6 + b
7 = b
y = (3/2)x + 7

1
Step-by-step explanation:
For this case we must indicate the value of the following expression, expressed in scientific notation:
![(1.2 * 10^{-3}) * (1.1 * 10^{8}) =](https://tex.z-dn.net/?f=%281.2%20%2A%2010%5E%7B-3%7D%29%20%2A%20%281.1%20%2A%2010%5E%7B8%7D%29%20%3D)
We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:
![a ^ n * a ^ m = a ^ {n + m}](https://tex.z-dn.net/?f=a%20%5E%20n%20%2A%20a%20%5E%20m%20%3D%20a%20%5E%20%7Bn%20%2B%20m%7D)
Then, rewriting the expression we have:
![(1.2 * 1.1) * 10 ^{- 3 + 8} =\\1.32 * 10 ^ 5](https://tex.z-dn.net/?f=%281.2%20%2A%201.1%29%20%2A%2010%20%5E%7B-%203%20%2B%208%7D%20%3D%5C%5C1.32%20%2A%2010%20%5E%205)
Answer:
![1.32 * 10 ^ 5](https://tex.z-dn.net/?f=1.32%20%2A%2010%20%5E%205)

Step-by-step explanation:
Answer:
A) 4.77%.
B) 5%.
Step-by-step explanation:
Given that Adam borrows $ 6,000 from his parents today for university fees and he promises to pay a lump sum of $ 6,900 in 3 years' time, to calculate the effective annual interest rate and the equivalent simple annual interest rate the following calculations must be performed:
A)
6,900 = 6,000 x (1 + X / 1) ^ 3x1
6,900 = 6,000 x 1X ^ 3
6,900 = 6,000 x 1 x 4.77 ^ 3
Thus, the interest rate of said investment is 4.77% per year.
B)
(6,900 - 6,000) / 3 = 300
6,000 = 100
300 = X
300 x 100 / 6,000 = X
30000 / 6,000 = X
5 = X
Thus, the simple interest rate would be 5% per year.
