Solving steps:

Question:. Francisco has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater. He needs 112 points for a free movie ticket. How many visits must Francisco make to earn a free movie ticket?

Find out: How many visits required for 112 points.

Solution: Let's make an equation

=> 55 + 9.5x = 112

Let's make x the subject of formula

=> 9.5x = 112 - 55

Substract 55 from 112

=> 9.5x = 57

Divide both sides by 9.5

=> [tex] \frac{9.5x}{9.5} = \frac{57}{9.5} [/tex]

Divide

=> x = 6

Therefore Francisco needs 6 visit to earn a free movie ticket

The number of visits Francisco must make to earn a free movie ticket is 6.

Given that, Francisco receives 55 rewards points just for signing up. He earns 9.5 points for each visit to the movie theater.

Let the number of visits to the movie theater be x.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

He needs 112 points for a free movie ticket.

Now, the equation is [tex]9.5x+55=112[/tex]

[tex]9.5x=112-55[/tex]

[tex]9.5x=57[/tex]

[tex]x=\frac{57}{9.5}[/tex]

[tex]x=6[/tex]

Therefore, the number of visits Francisco must make to earn a free movie ticket is 6.

The temperature in a particular city to decrease at a constant rate of 3°F per hour.

An equation is an expression that shows the relationship between two or more numbers and variables.

At 2:00 a.m., the temperature was 54 degrees Fahrenheit, and at 5:00 a.m., the temperature was 45 degrees Fahrenheit. Hence:

Rate of change = (45°F - 54°F) / (5 - 2) = -3

Expression consist of numbers, variables, and mathematical operations. The equation that is true is x²+mx+m= (x+2)².

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As it is given that the x²+mx+m is a perfect square trinomial, and we know that the general equation of perfect square trinomial  is given as,

ax²+bx+c=0

where a,b and c are real numbers, and a≠0,

if we compare the equation with our equation

[tex]ax^2+bx+c=0\\x^2+mx+m=0[/tex]

We will get the value of 'a' as 1, b=c=m, therefore, we need a binomial which is when expanded then in its perfect square trinomial the value of b=c, therefore, the only feasible option here is (x+2)².

Hence, the equation that is true is x²+mx+m= (x+2)².

Answer: a rotation about point A

Step-by-step explanation:

The rigid transformation would map ΔAQR to ΔAKP is rotation about point A.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have to transform ΔAQR to ΔAKP.

We know that,

Point A is invariant, so we that it cannot be rotation about point R.

Also, the orientation is same then reflection is not happening here.

So, there is rotation about the point A.
