A used car has a value of 15,250 when it’s purchased in 2012. The value of the car decreases at a rate of 7.5% per year
kotegsom [21]

p=15250

r=7.5/100=0.075

y = 15250*(1 - 0.075)^x

after 8 years it would be

x = 8

y = 15250*(1 - 0.075)^8

y = $8,173.42

after 8 years the value of the car is going to be $8,173.42

What is the distance between (-3,5) (7,5)
Firlakuza [10]

Answer:

10 units

Step-by-step explanation:

use distance formula:  d = square root of the difference of the y-values minus the difference of the x-values

d = \sqrt{(5-5)^2+(7--3)^2}

d = \sqrt{(0)^2+(10)^2}

d = \sqrt{100}

d = 10 units

A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;

x = 1, y = 5.0125

B) The possible solutions of the given equation will be; x = 3.11 or -3.11

C) The solution to p(x) = g(x) is; x = 0 and y = 0

<h3>How to find the solution to simultaneous equations graphically?</h3>

When we are trying to solve two simultaneous equations, there are three methods we can use namely;

1) Elimination Method

2) Substitution Method

3) Graphical Method

Now, we see that we are to use the graphical method from the given graph.

Now, the solution to the given pair of equation will be the coordinates of the points where both graphs intersect.

A) From the given graph, we can see that the point where graph functions p(x) and f(x) intersect is seen to be;

x = 1, y = 5.0125

B) The possible solutions of the given equation will be the point where f(x) = 0 which is where the line crosses the x-axis and so we have;

x = 3.11 or -3.11

C) The solution to p(x) = g(x) is the coordinate;

x = 0 and y = 0

Solving a word problem involving rates and time conversion
LUCKY_DIMON [66]

Answer:

It takes 4.75 hours to travel 247 miles.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

A car travels at an average speed of 52 miles per hour.

This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?

1 h - 52 m

x h - 247 m

Applying cross multiplication

52x = 247

x = \frac{247}{52}

x = 4.75

It takes 4.75 hours to travel 247 miles.
