Answer:

Solution of the given equations is (-5,2)

Step-by-step explanation:

We have been given the following system of equations:

y = (2/5)x + 4

y = 2x + 12

The solution of the system of equation can be found by finding the point of intersection of both lines on the graph. The graph of both equations is attached below.

As we can see that both the lines intersect each other at one point, and that point is (-5,2). So the solution of the given equations is (-5,2)

The value of a vintage car over time is represented by the function V(t)=24,300(1.37)t , where t is the time in years. What is t
Nimfa-mama [501]

Answer:

For the function V(t)=24300(1.37)t, the rate of increase is 37%.  

Step-by-step explanation:

The function represents the value (V) of the car over time (t).  This type of function is exponential growth, which means for each year, the value of the vintage car will increase by a rate of 37%.  Exponential growth functions are represented by the equation f(x)=ab^x, where 'a'=initial value, 'b'=the rate and 'x' represents time.  In this case, our initial value of the car is $24,300 and the rate is 1.37.  A rate of 1.37 indicates that the car will retain its initial value (1) as well as increase be an additional 37 percent (.37) over time.

The number 0.7777 repeats forever therefore it is irrational true or false?
DochEvi [55]

Answer:

It's false, this number is a rational number.

Step-by-step explanation:

It's false, the kind of decimal where the same digits repeats forever are known as periodic decimals and they can be represented with fractions therefore they are a part of the rational numbers. To represent this number in a fraction form we need to first identify the part that repeats, in this case it's 7, since it's only one number we can insert it in the numerator and the denominator will have a 9, if it were two numbers the denominator would have a 99 and so on. So in this case:

7/9 = 0.7777...

An unusual number cube (with 6 sides) has the numbers 2, 2, 4, 4, 6, and 6 on its faces.
Hunter-Best [27]

P(2 or 4) = 2/3

p(multiple of 2) =  1

p(multiple of 3) = 1/3

P(odd prime numbers) = 0

<h3>What are the probabilities?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

P(2 or 4) = (number of sides that have a value of 2 / total number of sides) + (number of sides that have a value of 2 / total number of sides) = 2/6 + 2/6 = 2/3

p(multiple of 2) = number of sides that are a multiple of 2 / total number of sides

6/6 = 1

p(multiple of 3) = number of sides that are a multiple of 3/ total number of sides

= 2/6 = 1/3

P(odd prime numbers) = number of odd prime numbers / total number of sides  = 0
