Which of the following is not a congruence transformation? A.Translating
B.Rotating
C.Dilating

Answers

Answer 1
Answer: The answer is C.) Dilating 
because dilating doesn't make them congruent anymore, but they change size to be either smaller or bigger than one another, but the shape itself does not change.

The angles in a triangle add up to 180°.

180 - 118 - 34 = 28

In how many different ways can 3 identical green shirts and 3 identical red shirts be distributed among 6 children such that each child receives a shirt

Answers

Answer:

Total number of ways will be 20

Step-by-step explanation:

We have given three identical green shirts and three identical red shirts

So total number of shirts = 3+3 = 5

We have to distribute these shirts to 6 children so that each children got one shirt

Number of ways will be equal to =(6!)/(3!3!)=20 ( Here we divide by 3!3! because three green shirts and 3 red shirts are identical )  

(x − 2) is a factor of x4 + 2x3 − 7x2 − 8x + 12. The other factors are ___, ___, and ___.

Answers

The all other 3 factors of the equation  x⁴ + 2x³ − 7x² − 8x + 12 will b e(x + 2),(x - 1) and (x + 3).

What are the roots of an equation?

Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.

For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.

Given the equation,

x⁴ + 2x³ − 7x² − 8x + 12

If (x - 2) is a factor of the equation then it should be divisible by it.

So,

(x⁴ + 2x³ − 7x² − 8x + 12) / (x - 2) = (x³ + 4x² + x - 6)

Now divide by (x - 1) of  (x³ + 4x² + x - 6)

(x³ + 4x² + x - 6) / (x - 1) = x² + 5x + 6

So,

⇒ (x - 2)(x - 1)(x² + 5x + 6)

⇒  (x - 2)(x - 1)( x² + 2x + 3x + 6)

⇒   (x - 2)(x - 1)[ x(x + 2) + 3(x + 2) ]

⇒  (x - 2)(x - 1)(x + 2)(x + 3)

Hence "The all other 3 factors of the equation  x⁴ + 2x³ − 7x² − 8x + 12 will b e(x + 2),(x - 1) and (x + 3)".

Answer:

Step-by-step explanation:

The given equation is:

x^4+2x^3-7x^2-8x+12

Now, (x-2) is a factor of the given equation, therefore

(x-2)(x^3+4x^2+x-6)

(x-2)(x-1)(x^2+5x+6)

(x-2)(x-1)(x^2+3x+2x+6)

(x-2)(x-1)(x(x+3)+2(x+3))

(x-2)(x-1)(x+2)(x+3)

Therefore, the other factors are (x-1), (x+2) and (x+3).

Which graph represents the linear function y=-2x+3

Answers

The coordinates will be (0, 3) and (1.5, 0), and mark these points on the paper and make a straight line.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The linear function is given below.

y = -2x + 3

Then the graph of the equation will be

Put x = 0, then the value of y will be

y = -2(0) + 3

y = 3

Put y = 0, then the value of x will be

2x = 3

 x = 1.5

Then the coordinates will be (0, 3) and (1.5, 0).

Mark these points on the paper and make a straight line.

The graph is given below.
