if triangle ABC=triangle DEC, and angle b=3x and angle e=6x-39, what is x

Answers

Answer 1
If angle b and angle e are the same, I guess you can write b=e ?
So you’ll have :
3x = 6x - 39
0 = 6x - 3x - 39
39 = 3x
x = 39/3
x = 13
Answer 2

The value of x in the expression is 13.

What is a Triangle?

A polygon which has three sides and three vertices is called as triangle.

The sum of all the angles of the triangle is 180°.

Given:

The triangle ABC = triangle DEC,

and angle b=3x and angle e=6x-39.

To find the value of x:

We know,

b = e

So, substituting the values,

3x = 6x - 39

3x = 39

x = 13.

Therefore, the value of x is 13.

PLEASE HURRY

Answers

Answer:

The correct answer is C(11,7)

Step-by-step explanation:

I had this question and got it right lol

The required coordinates of the preimage are (-7, 11) when the point is rotated 270° about the origin.

What is a transformation?

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

We have been given that a point is rotated 270° about the origin. The image of the point is (-11,7).

The coordinates of the preimage would be :

x  = x cos θ + y sin θ

y = x sin θ + y cos θ

Here x = -11 ,y = 7 and θ = 270°

Substitute the values in the above equations,

x  = (-11) cos 270° + 7 sin 270° = -7

y = (-11) sin 270° + 7 cos 270° = 11

Therefore, the required coordinates of the preimage are (-7, 11).

Answers

Answer:

-21/5 or -4.2

Step-by-step explanation:

y = 2x + 6

3y - x + 3 = 0

Substitute the value for y from the first equation into the second equation.  Solve for x.

3y - x + 3 = 0

3(2x + 6) - x  + 3= 0

6x + 18 - x + 3 = 0

5x + 18 + 3 = 0

5x + 21 = 0

5x + 21 - 21 = 0 - 21

5x = -21

x = -21/5 or -4.2

2.9(-1) = 0
3.x + 1 is a factor of g(x).
4. No conclusion can be made regarding g(x).

Answers

Answer:

g(1) = 0

There is a remainder of 10 so you can automatically cross out 3 and 4.

When [tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex] is divided by x - 1, the only true conclusion is g(1) = 0

The given equation is:

[tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex]

x- 1 is a factor of [tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex] only if g(1) = 0

Let us find g(1) by substituting x = 1 into [tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex]

[tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex]

[tex]g(1) = 1^4+2(1^3)-7(1^2)-8(1)+12\\\\g(1) = 1 + 2 - 7 - 8 + 12\\\\g(1) = -12 + 12\\\\g(1) = 0[/tex]

Therefore, when [tex]g(x) = x^4 + 2x^3-7x^2-8x+12[/tex] is divided by x - 1, the only true conclusion is g(1) = 0

Colin can type 1500 in 30 minutes.

Brian can type 2200 words in 40 minutes.

To find:

The person who types at the fastest rate of words per minute.

Solution:

We know that,

[tex]\text{Rate of words per minute}=\dfrac{\text{Number of words}}{\text{Number of minutes}}[/tex]

Using this formula, we get

[tex]\text{Henry's rate of words per minute}=\dfrac{3500}{70}=50[/tex]

[tex]\text{Colin's rate of words per minute}=\dfrac{1500}{30}=50[/tex]

[tex]\text{Brian's rate of words per minute}=\dfrac{2200}{40}=55[/tex]

Since 55>50, therefore Brian's types at the fastest rate of words per minute.
