Which equations represent the line shown in the graph?
zaharov [31]
The given graph is a straight line passing through points (-4, -3) and (1, 5)
Equation in point slope form is y + 3 = (5 - (-3))/(1 - (-4)) (x - (-4))
y + 3 = 8/5(x + 4)
y + 3 = 8/5x + 32/5
y = 8/5x + 32/5 - 3
y = 8/5x + 17/5

Multiplying through by 5 gives
5y = 8x + 17
-8x + 5y = 17
Options B and C are the correct answers.

What lump sum do parents need to deposit in an account earning 9%, compounded monthly, so that it will grow to $100,000 for thei
gogolik [260]

Answer:

They need to deposit $31,172.49

Step-by-step explanation:

The compound interest formula is given by:

A = P(1 + \frac{r}{n})^{nt}

Where A is the amount of money, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time the money is invested or borrowed for, in years.

In this problem

We want to find P for which A = 100000 when r = 0.09, n = 12, t = 13

So

A = P(1 + \frac{r}{n})^{nt}

100000 = P(1 + \frac{0.09}{12})^{12*13}

3.208P = 100000

P = \frac{100000}{3.208}

P = 31172.49

They need to deposit $31,172.49
