Answer:

-3

Step-by-step explanation:

Given the function f(x) = -(-x)

we want to evaluate f(-3)

What we do simply here is substitute the value of -3 for x in the equation

That would be ;

f(-3) = -(-(-3)) = -(3) = -3

the singh and robinson families planned a trip to busch gardens. they needed to buy one ticket per person and then pay for parki
hjlf

Let x represent cost of each ticket and y represent cost of parking.

We have been given that the Singh's spent $335 for 5 people and parking. We can represent this information in an equation as:

5x+y=335...(1)

We are also told that the Robinson spent $465 for 7 people and parking. We can represent this information in an equation as:

7x+y=465...(2)

Now we will use elimination method to solve our given system of equations.

Upon subtracting equation (1) from equation (2), we will get:

7x-5x+y-y=465-335

2x=130

\frac{2x}{2}=\frac{130}{2}

x=65

Therefore, the each ticket costs $65.

Upon substituting x=65 in equation (1), we will get:

5(65)+y=335

325+y=335

325-325+y=335-325

y=10

Therefore, the parking costs $10.

Number of fruits = 5

Number of bowls = 3

Number of ways to put the fruits in the bowls = ?

Consider the number of choices for each fruit.

There are three bowls where you can place that fruit. So for all five fruits, there are a total of:

8. Given: PQR and TSR are right triangles,
rewona [7]

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are scalene, right angled, isosceles, equilateral.

A right angled triangle is a triangle with one angle equals to 90°.

Statement                      Reason

∠PQR = ∠RST                Given. ∠PQR = ∠RST = 90° (definition for right

                                       angle triangle.

PQ = ST                          Given

PR ≅  RT                         Since R is the midpoint of PT, hence PR = RT

ΔPQR ≅ ΔTSR                Side-angle-side triangle congruence theorem.

                                       the Side-angle-side triangle congruence theorem

                                       states that if two sides and an included angle of

                                       one triangle is equal to two sides and an included

                                       angle of another triangle, then the two triangles

                                       are congruent. PQ=ST, PR = RT and ∠PQR = ∠TSR
