Jill rented (B) 2 movies that month.

<h3>What is an equation?</h3>

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.

To find how many movies did Jill rent online that month:

The equation for the monthly bill when m number of movies are rented per month = 9.80 +1.5m.
Given, 9.80 + 1.5m=12.80
1.5m = 3
m = 2

Therefore, Jill rented (B) 2 movies that month.

You are on a game show and you are given the choice of three doors. Behind one door is a car (the main prize). Behind each of th

makvit [3.9K]

Answer:

You need to switch doors.

Switching the door has higher probability of winning.

Step-by-step explanation:

Consider the provided information.

Suppose there are 3 doors, A, B and C

Behind one door is a car that means the probability of getting a car is 1/3

Suppose you select door A

The probability that the it has a goat is 2/3. That means it is very likely to be a goat behind door A.

The other two door(B and C) are more likely to contain a goat and car.

The host opens another door which has a goat behind it. Let say he open the door B.

Now there is more chance to be a car behind it as compare to the previous choice.

Thus, you need to switch doors.

Switching the doors will gives you 2 in 3 chance of winning while staying with same door will gives you 1 in 3 chance of winning.

Switching the door has higher probability of winning.

The expression that represents Lonnie's final number is 2(x + 3) - 6

<h3>Writing an expression</h3>

From the given information, we are to write the expression that represents Lonnie's final number

From the given information,

"<em>kristy asks lonnie to think of a number, add 3 to it</em>"

Let the number be x

Then,

The statement becomes

x + 3

<em>"multiply the sum by 2</em>" we get

2×(x +3)

= 2(x + 3)

"<em> subtract 6</em>",

The expression becomes

2(x + 3) - 6

This is the expression that represents Lonnie's final number

Hence, the expression that represents Lonnie's final number is 2(x + 3) - 6

The vertex of a parabola is (3,2). A second point on the parabola is (1,5).which of the following points is also on the graph?

vekshin1

+ <span>The vertex of a parabola is (3,2),
that means the parabola's equation is y=a(x-3)</span>²+2
+ <span>A second point on the parabola is (1,5) and we replace x=1 and y=5. We have:
5</span>=a(1-3)<span>²+2 , so we have 4a=5-2 or a=3/4
So the equation is y=3/4 (x-3)</span>²+2

And by checking we have the point (5;5) is on the parabola
