Reflection of point (x ,y) about x axis is given by (x,-y) and about y axis is given by (-x,y) .treat the line as plane mirror about which you have to find out point reflection .thus Q is (5 ,-6) and R is(-5,6)..

BRAINLYYYY PLUS 100 PointsThe difference between two numbers is 84 and their sum is 278. What are the numbers? Hint( answer is x
den301095 [7]

Answer:

x = 181 and y = 97

Step-by-step explanation:

let called the first number is x

the second number would be called y

We are given that:

x + y = 278 (1)

x = y + 84 (2)

Let change x in (2) into (1):

y + 84 + y = 278

2y + 84 = 278

Subtract 84 from both side, we got:

2y + 84 - 84 = 278 - 84

2y + 0 = 194

Divide both side by 2, we got:

2y / 2 = 194 / 2

y = 97

Because y = 97 and x + y = 278 so x would equal:

x + 97 = 278

Subtract 97 from both side, we got:

x + 97 - 97 = 278 - 97

x + 0 = 181

x = 181 and y = 97

Hope this helped :3

Which statement is true regarding the functions on the graph?
sergey [27]

Answer:

f(3) = g(3)

General Formulas and Concepts:

<u>Algebra I</u>

  • Reading a Coordinate Graph
  • Coordinates (x, y)
  • Solving systems of equations by graphing
  • Functions
  • Function Notation

Step-by-step explanation:

According to the graph, we see that both lines intersect at <em>x</em> = 3. Therefore, that means both lines at that <em>x</em> point will have the same <em>y</em> value. Both f(3) and g(3) would equal 6, leading us to the answer of f(3) = g(3).

Someone please help me with the perimeter and area of this problem
Tcecarenko [31]

Answer: Perimeter = 40

               Area = 204

Step-by-step explanation:

Perimeter is the sum of all the sides:

    11 + 12 + 17 = 40

The area of a triangle is 1/2 base x height

   1/2( 17 x 24)

   1/2( 408) = 204
