Answer:

The value of x = 4

so

Step-by-step explanation:

We know that an angle bisector bisects the angle into two equivalent angles.

When BD bisects angle ABC, it forms two equivalent angles which are:

such as

m∠ABD = m∠CBD

as

m ∠ABD = 6x-8

m∠CBD = 3x+4

so the equation becomes

m∠ABD = m∠CBD

6x-8 = 3x+4

6x - 3x = 4 + 8

3x = 12

Divide both sides by 3

x = 4

Thus, the value of x = 4

so

Answer:

A. Yes

B. Yes

C. No

D. No

Step-by-step explanation:

A is a linear equation, because it has an x with no exponent

B is a linear equation, because it has an x with no exponent

C is not a linear equation, because the exponent is more than 1

D is not a linear equation, because the exponent is more than 1

Answer:

2x-3y+3=0

2x+y-3=0

Step-by-step explanation:

For 41.

points are (0,1) and (3,3)

Equation in two point form is

(x - 0)(3-1) = (3-0) ( y-1)

2x= 3y - 3

2x-3y+3=0

For 42.

Points are (0,3) and (2,-1)

Equation is

(x-0)(-1-3)=(y-3)(2-0)

-4x = 2y -6

4x + 2y -6 = 0

or 2x + y -3 = 0

Answer:

y=-5/3x+1

Step-by-step explanation:

The answer is y=-5/3x+1 because you would do the exact opposite of rise over run where it rises 5 units up and 3 units shifted right but instead it is still 3 units that are shifted to the right but 5 units down.  We can also assume that the y-intercept is 1 based on where the slope is placed.

Answer:Number 1 I think is -24 because the minus sign is right next to the () so that means multiply so - times negative is + 24 but then it says opposite so 24

number 2 I think 8 because positive times negative is negative then the opposite is positive 8

number 3 is -15 cause positive times positive is positive then the opposite of  15 is -15

number 4 is positive 33 because negative times positive is negative then the opposite is postive 33

number 5 is 40

and number 6 is -6 hope this helps

An expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]

For a complex number z = a + ib, the trigonometric form is  [tex]r(cos\theta +isin\theta)[/tex]

where [tex]r=|\sqrt{a^{2} +b^{2} } |[/tex] and [tex]\theta=tan^{-1}(\frac{b}{a} )[/tex]

For given question,

We need to find the cube root of -8

[tex]\sqrt[3]{-8}[/tex]

We can write above number as complex number.

[tex]\sqrt[3]{-8}\\ =\sqrt[3]{8\times (-1)}\\ =\sqrt[3]{8}\times \sqrt[3]{-1}\\ =2 \times(-1)^\frac{1}{3}[/tex]

Consider a complex number z = -1

We can write -1 in trigonometric form as, [tex]-1=cos(\pi)+isin(\pi)[/tex]

We know, [tex](cos\theta +isin\theta)^{\frac{1}{n} }=(cos(\frac{1}{n} \theta )+isin(\frac{1}{n} \theta))[/tex]

So,

[tex](-1)^{\frac{1}{3} }\\\\=(cos\pi+i~sin\pi)^{\frac{1}{3} }\\\\=cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} )[/tex]

Therefore, an expression that represents a cube root of -8 is [tex]2(cos(\frac{\pi}{3} )+i~sin(\frac{\pi}{3} ))[/tex]

The answer is the first one:  -4 on Edge

Step-by-step explanation:

The y-value of the solution to the system of linear equations given is: A. -4.

Given two linear equations, such as:

4x + 5y = −12 --> Eqn. 1

-2x + 3y = −16 --> Eqn. 2

Multiply eqn. 1 by 2 and eqn. 2 by 4

8x + 10y = −24 --> Eqn. 3

-8x + 12y = −64 --> Eqn. 4

Add to eliminate x

22y = -88

22y/22 = -88/22

y = -4

The y-value of the solution is: A. -4.

Answer: The total will drop by 20%

For x = 0.33, the events G and H are mutually exclusive.

Here, we are given that-  

P(G) = 0.4

P(H) = x

and P(G or H) = 0.73

⇒ P(G∪H) = 0.73

Now, we know that-

P(G U H) = P(G) + P(H) - P(G ∩ H)

For any two events that are mutually exclusive, the probability that they occur at the same time is 0. Hence, if G and H are mutually exclusive, then P(G ∩ H) will be 0

⇒ 0.73 = 0.4 + x - 0

x = 0.73 - 0.4

x = 0.33

Thus, for x = 0.33, the events G and H are mutually exclusive.

mean=6.4

standard deviation=0.6

we have to find the range in which at least 75% of the data will reside

1-1/k²=0.75

1/k²=1-0.75

1/k²=0.25

k²=1/0.25=4

k=2

so, k=2

The range of values can be computed as mean±k(standard deviation).

Answer:

64

Step-by-step explanation

Using proportions, the amounts you have of each block are given as follows:

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

From the amounts given, you can create the following ratio:

Blue : Yellow : Orange : Red

6 : 4 : 1 : 0.25.

Hence the fractions corresponding to each color are given as follows:

Hence the number of blue blocks is found as follows:

6/11.25 x 47964 = 25,581.

The number of yellow blocks is given by:

4/11.25 x 47964 = 17,054.

The number of orange blocks is given by:

1/11.25 x 47964 = 4,263.

The number of red blocks is given by:

0.25/11.25 x 47964 = 1,066.
