What is the solution to y = x + 2 and y = 3x – 2 and how do you know? PLEASE HELPPPPP! THANK U!

Nutka1998 [239]

Answer:

(2,4)

Step-by-step explanation:

We have the system:

y=x+2

y=3x-2.

This is already setup for substitution.

I'm going to replace my first y with what the second y equals.

That is, I'm going to write 3x-2=x+2.

Time to solve the following for x:

3x-2=x+2

Subtract x on both sides:

2x-2= 2

Add 2 on both sides:

2x. = 4

Divide both sides by 2:

x. = 2

Now that we know x=2 and we have an equation that relates x to y: either y=x+2 or y=3x-2, doesn't matter which we use, we can find y.

So we y=x+2 with x=2 which means y=2+2=4.

So the solution, the intersection, is (2,4).

The Carter Motor Company claims that its new sedan, the Libra, will average better than 31 miles per gallon in the city. Assumin

Answer:

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis $H_a : \mu > 31$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 31 \ miles / gallon$

Generally

The null hypothesis is that the company's new sedan, the Libra, will have an average of $\mu = 31 \ miles / gallon$

This mathematically represented as

The null hypothesis $H_o : \mu = 31$

The alternative hypothesis is that the company's new sedan, the Libra, will have an average better than $\mu = 31 \ miles / gallon$

This mathematically represented as

The alternative hypothesis $H_a : \mu > 31$
