Luden [163]3 years ago

6 0

Answer:

(- 1, 9 )

Step-by-step explanation:

Given the 2 equations

y = - 3x + 6 → (1)

y = 9 → (2)

Substitute y = 9 into (1) and solve for x

9 = - 3x + 6 ( subtract 6 from both sides )

3 = - 3x ( divide both sides by - 3 )

- 1 = x

Solution is (- 1, 9 )

Question 10 (3 points)

Zinaida [17]

Answer:

$3,090.64

Step-by-step explanation:

We shall allocate a random letter to each value, with that I explain the formula.

Initial value of investment = $5,003.86 = P

Rate of interest = 3.7% = R

Compounding interval in a year = 365 = I

Total period = 13 years = T

Value of investment in compound interest formula shall be:

$= P \times (1 + \frac{R}{(I})^{(I \times T)}$

Now, putting values in the above equation:

$= 5,003.86 \times (1 + \frac{0.037}{365}) ^{(365\times13)}$

= $8,094.50

Thus, interest earned = Total value of investment on maturity - Initially invested amount

= $8,094.50 - $5,003.86 = $3,090.64
