Please help!!!!! Pre algebra (8th grade math) 2 questions double the points!!! At least help me with one;( Very easy but I’m not

dusya [7]

Answer:

11.)

We can let the scores we don't know by x, and we know that tokay had 14 more points than Lodi. This can be shown as the following:

x + (x+14) = 162

2x+14=162

162-14= 148

148/2 = 74

Therefore Lodi scored 74 points.

12.)

We can substitute the prices we don't know by x and have the following:

4x+x=6.50

5x=6.50

6.50/5= 1.3

4x1.3= 5.2

Therefore the sandwich cost $5.20 and the drink costs $1.30

In 2012 your car was worth $10,000. In 2014 your car was worth $8,850. Suppose the value of your car decreased at a constant rat

monitta

Answer:

The function to determine the value of your car (in dollars) in terms of the number of years t since 2012 is:

$f(t) = 10000(0.9407)^t$

Step-by-step explanation:

Value of the car:

Constant rate of change, so the value of the car in t years after 2012 is given by:

$f(t) = f(0)(1-r)^t$

In which f(0) is the initial value and r is the decay rate, as a decimal.

In 2012 your car was worth $10,000.

This means that $f(0) = 10000$ , thus:

$f(t) = 10000(1-r)^t$

2014 your car was worth $8,850.

2014 - 2012 = 2, so:

$f(2) = 8850$

We use this to find 1 - r.

$f(t) = 10000(1-r)^t$

$8850 = 10000(1-r)^2$

$(1-r)^2 = \frac{8850}{10000}$

$(1-r)^2 = 0.885$

$\sqrt{(1-r)^2} = \sqrt{0.885}$

$1 - r = 0.9407$

Thus

$f(t) = 10000(1-r)^t$

$f(t) = 10000(0.9407)^t$
