I am joyous to assist you anytime.

Option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.

What is transformation of rotation?

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The graph shows the parallel lines p, q and p', q' in the plane.

The parallel lines p and q coincide with parallel lines p' and q' when we transformed the parallel lines by counterclockwise rotation 90°  about the origin.

After this transformation of rotation, the parallel lines p and q will coincide with parallel lines p' and q'.

Hence we can conclude that option (A) counterclockwise rotation 90° about the origin makes the the parallel lines p and q will coincide with parallel lines p' and q' is the correct answer.

solve by substitution or elimination 5x+3y=-15 -8x-2y=10

Answers

Answer:

x=0, y=-5

Step-by-step explanation:

The system is

(1)  5x+3y=-15  

(2) -8x-2y=10

Let's solve it by elimination.  In order to do it, you have to multiply the equations by suitable numbers in such a way that when you add the 2 equations, one of the unknowns is eliminated

Multiply (1) by 2 and (2) by 3

(1) 10x+6y=-30

(2) -24x-6y=30

Add the two equations

10x-24x+6y-6y=-30+30 ----> -14x=0---->x=0

Now replace this value in any equation, for example in (1)

6y=-30 ----> y=-30/6----> y=-5

Answer:  The required solution is (x, y) = (0, -5).

Step-by-step explanation:  We are given to solve the following system of equations by the method of substitution or elimination :

[tex]5x+3y=-15~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-8x-2y=10~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

We will be solving the given system by substitution method.

From equation (ii), we have

[tex]-8x-2y=10\\\\\Rightarrow -4x-y=5\\\\\Rightarrow y=-4x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (i), we get

[tex]5x+3(-4x-5)=-15\\\\\Rightarrow 5x-12x-15=-15\\\\\Rightarrow -7x=0\\\\\Rightarrow x=0.[/tex]

From equation (iii), we get

[tex]y=-4\times0-5=-5.[/tex]

Thus, the required solution is (x, y) = (0, -5).

Answers

Answer:

y = -2 2/5

Step-by-step explanation:

-3(y+3)=2y+3

-3y - 9 = 2y + 3

-3y - 2y = 3 + 9

    -5y   = 12

        y = 12/-5  = -12/5 = - 2 2/5

-3(y+3)=2y+3

Mutiply the bracket by -3

(-3)(y)= -3y

(-3)(3)= -9

-3y-9= 2y+3

Move -9 to the other side

Sign changes from -9 to +9

-3y-9+9= 2y+3+9

-3y= 2y+3+9

-3y= 2y+12

Move 2y to the other side

Sign changes from +2y to -2y

f (5) times g (5)
f (5) + g (5)
5 f (5)
5 g (5)

Answers

Answer:

Option A.

Step-by-step explanation:

Expression given in the question is (f g)(5).

We know when two functions are f(x) and g(x) then (f g)(x) represents the multiplication of two functions.

(f g)(x) = f(x).[g(x)]

For x = 5

(f g)(5) = f(5).g(x)

It may be represented by the operation as

(f g)(5) = f(5) × g(x)

Therefore, option A. will be the answer.

The function (f g)(5) can be expressed as f(5) × g(5) as an equivalent expression.

Equivalent expression to (f g)(5)

The equivalent expression is determined as follows;

Two given functions such as  (f(5) and g (5), can be represented by the multiplication of the two functions as shown below.

(f g) (5) = (f (5) x g (5)

(f g) (5) = (f (5) x g (5)

Which quadratic function only has one x-intercept?


A f ( x ) = x 2 − 12 x + 36

B f ( x ) = x 2 − 13 x + 36

C f ( x ) = x 2 + 13 x + 36

D f ( x ) = x 2 + 20 x + 36

Answers

Answer:

f(x) = x² - 12x + 36 = (x - 6)²

The correct answer is A.

The quadratic function that has only one \(x\)-intercept is A. [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]

A quadratic function has only one [tex]\(x\)[/tex]-intercept if it touches the [tex]\(x\)[/tex]-axis at exactly one point, which happens when the discriminant [tex](\(\Delta\))[/tex] of the quadratic equation is zero. The discriminant of a quadratic function [tex]\(ax^2 + bx + c = 0\)[/tex] is given by:

[tex]\[ \Delta = b^2 - 4ac \][/tex]

Let's calculate the discriminant for each given function to determine which one has only one [tex]\(x\)[/tex]-intercept.

Option A: [tex]\( f(x) = x^2 - 12x + 36 \)[/tex]

[tex]\[ a = 1, \, b = -12, \, c = 36 \][/tex]

[tex]\[ \Delta = (-12)^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 144 - 144 \][/tex]

[tex]\[ \Delta = 0 \][/tex]

Option B: [tex]\( f(x) = x^2 - 13x + 36 \)[/tex]

[tex]\[ a = 1, \, b = -13, \, c = 36 \][/tex]

[tex]\[ \Delta = (-13)^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 169 - 144 \][/tex]

[tex]\[ \Delta = 25 \][/tex]

Option C: [tex]\( f(x) = x^2 + 13x + 36 \)[/tex]

[tex]\[ a = 1, \, b = 13, \, c = 36 \][/tex]

[tex]\[ \Delta = 13^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 169 - 144 \][/tex]

[tex]\[ \Delta = 25 \][/tex]

Option D: [tex]\( f(x) = x^2 + 20x + 36 \)[/tex]

[tex]\[ a = 1, \, b = 20, \, c = 36 \][/tex]

[tex]\[ \Delta = 20^2 - 4 \cdot 1 \cdot 36 \][/tex]

[tex]\[ \Delta = 400 - 144 \][/tex]

[tex]\[ \Delta = 256 \][/tex]

Only option A has a discriminant of 0, which means it has exactly one \(x\)-intercept.
