Answer (-1 , -8)

-----------------------------------
Check Equation -6(0.75)ˣ
-----------------------------------
when x = -1
y = -6(0.75)⁻¹
y = -6(4/3)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)

-----------------------------------
Check Equation y = 4(x - 1)
-----------------------------------
When x = -1 
y = 4( - 1 -1)
y = 4(-2)
y = -8

When x = -1, y = -8, therefore this equation passes through (-1, -8)

-----------------------------------
Answer (B): (- 1, -8)

MakcuM [25]

Answer:

It will take 55 years for the account value to reach 38200 dollars

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

In this problem, we ahve that:

T = 38200, P = 7500, I = 0.075

So

First we find how much we have to earn in interest.

38200 = E + 7500.

E = 38200 - 7500

E = 30700

How much time to earn this interest?

E = P*I*t

30700 = 7500*0.075*t

t = \frac{30700}{7500*0.075}

t = 54.6

Rounding up

It will take 55 years for the account value to reach 38200 dollars

igor_vitrenko [27]
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
