The investment worth after 42 years is $115200, so option 2 is correct

<u>Solution:</u>

Given, an investment of $1,800 doubles in value every 7 years. We have to find how much is the investment worth after 42 years from the given set of options.

\begin{array}{l}{\text { Now, after } 7 \text { years } \rightarrow 1800 \times 2=3600} \\\\ {\text { After } 14 \text { years } \rightarrow 3600 \times 2=7200} \\\\ {\text { After } 21 \text { years } \rightarrow 7200 \times 2=14400} \\\\ {\text { After } 28 \text { years } \rightarrow 14400 \times 2=28800} \\\\ {\text { After } 35 \text { years } \rightarrow 28800 \times 2=57600} \\\\ {\text { After } 42 \text { years } \rightarrow 57600 \times 2=115200}\end{array}

Hence, the investment worth after 42 years is $115200, so option 2 is correct.

A cell phone plan costs $200 to start. Then there is a $50 charge each month. Is there a proportional relationship between time
xxMikexx [17]

Answer:

.

Step-by-step explanation:

The equation is

y = 200+50x

This is not a proportional relationship because it does not go through the origin

If x=0, y does not equal 0

Me QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR?
maks197457 [2]

We write the equation in the form of directional.

y -1 = 6x               ⇔    y = 6x + 1

y - 1 = 3x              ⇔    y = 3x + 1

y - 7 = 2x - 6         ⇔    y = 2x - 6 + 7

                                    y = 2x + 1

y - 7 = x - 2           ⇔    y = x - 2 + 7

                                    y = x + 5

Equations cleverly arranged .

Point Q = (0,1)  

b factor , not only fits the last equation

In the drawing have engraved points Q and R are tangent linear function appropriate to that point . This graphics solution . y = 3x + 1

Answer b

We check choice by the system of equations , where substitute wartoćsi points Q and R to the model equations linear function

The result of equations confirmed our choice Answer b
