Mathematics
1 answer:
Marianna [84]3 years ago

Answer:

5. D

6. C

Step-by-step explanation:

<u>Question 5</u>

Lets plug in values of x and y into each equation to see which one works for the entire data set...

y=2x-4

1) Plug in -7 as x and -18 as y:

-18=2(-7)-4

2) Multiply:

-18=-14-4

3) Subtract:

-18=-18

The answers are the same, therefore the correct answer to question 5 is equation D. Keep in mind, you want to check ever single pair of points to make sure it works for all of them, I'm just not going to list that as it would make this answer a lot longer for no reason.

<u>Question 6:</u>

We know that the cost for the boat is $25 as a base price, and also costs an additional $1.30 per day for fuel.

The correct equation is C=25+1.30d, because we are adding 1.3 every single day.

What is the difference between hyperbola and parabola??​
g100num [7]

Answer:

1)A parabola is defined as a set of points in a plane which are equidistant from a straight line or directrix and focus.

The hyperbola can be defined as the difference of distances between a set of points, which are present in a plane to two fixed points is a positive constant.

2)A parabola has single focus and directrix

A hyperbola has two foci and two directrices

3)Eccentricity, e = 1(parabola)

Eccentricity, e>1(hyperbola)

4)The two arms present in a parabola should be parallel to each other

The arms present in hyperbola are not parallel to each other

5)It has no asymptotes(parabola)

It has two asymptotes(hyperbola)

Which ordered pair is in the solution set of 6x + 4y ≤ −2?
Nutka1998 [239]

Answer:

x≤ −2/3y + −1/3

Step-by-step explanation:

because...

Step 1: Add -4y to both sides.

6x + 4y + −4y ≤ −2+−4y

6x ≤ −4y −2

Step 2: Divide both sides by 6.

6x/6 ≤ \frac{-4y-2}{6}

x ≤ −2/3y + −1/3

Therefor, the answer is x≤ −2/3y + −1/3

* Hopefully this helps:) Mark me the brainliest:)!!

Suppose you drive an average of 13,000 miles per​ year, and your car gets 26 miles per gallon. Suppose gasoline costs ​$3.60 a g
kow [346]
I'm assuming you're trying to find out how much you'll spend annually on gas: first you would divide the total miles driven in a year (13,000) by your car's mpg (26) giving you a quotient of 500 (the amount of times you'll have to fill up your tank) from here you will need to multiply 500 times the cost of gas ($3.60) giving you a product of $1,800 spent on gas annually.
