Step-by-step explanation:

3x-3+x=4x-3

First you need to combine like terms on the left side of the equation

3x-3+x the like terms are 3x and x, remember there is always an invisible 1 next to x  

add them:

3x+x=4x

so now we have

4x-3=4x-3

- we are subtracting 3 on both sides of the equation add 3 to cancel out the three

4x-3   4x-3

  +3      +3

- The threes cancel out so we are left with

4x=4x

x=0

46. The midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.

Using this info,

We already know EF=11 so

[tex] \frac{1}{2} (8 + 2x - 4) = 11[/tex]

[tex]x + 2 = 11[/tex]

[tex]x = 9[/tex]

53. Apply Midpoint Formula

[tex]( \frac{x1 + x2}{2} \: and \: \frac{y1 + y2}{2} )[/tex]

Let find the midpoint of each side

KL (+2a/2, +2a/2), LM(-2a/2, 2a/2) MN(-2a/2, -2a/2) NK(2a/2, -2a/2)

So the midpoint of each side is

KL=(a,a)

LM= (-a,a)

MN=(-a,-a)

NK=(a,-a).

The slopes of these line is y2-y1/x2-x1

KL=2a/-2a=-a

LM=-2a/-2a=a

MN=-2a/2a=-a

NK=-2a/-2a=a

Let find the length of all sides. Since each coordinate has a form of 0 in it, we would just consider the finite value, 2a.

Distance of all sides are 2a.

Consider the midpoint, notice how each midpoint can be obtained by a rotation of 90-180-270 or 360 degrees about the origin of one of the midpoints. Since all the side lengths and slope are equal, a rigid transformation like a rotation would preserve the side lengths and midpoint of each line. It also proves rotational symmetry and the only 4 figure quadralaterial that has a 90,180,270, and/or 360 degrees rotational symmetry is a square.

The number of eggs, Bridget collect from the chickens this morning is 28.

Given that, Bridget collected the eggs her chickens had laid and gave ½ to her neighbor.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The equation for the given situation is (e/2)-6=8

⇒ e/2 = 8+6

⇒ e/2 = 14

⇒ e = 28

Hence, the number of eggs, Bridget collect from the chickens this morning is 28.

The number of eggs will be 28, which Bridget collected from the chickens this morning.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Given that, Bridget collected the eggs her chickens had laid and gave ½ to her neighbor.

The equation below represents Bridget's original collection.

⇒ (e/2) - 6 = 8

⇒ e/2 = 8 + 6

Apply the addition operation,

⇒ e/2 = 14

Multiply by 2 into both sides of the above equation

⇒ 2 × e/2 = 2 × 14

⇒ e = 28

Therefore, the number of eggs will be 28, which Bridget collected from the chickens this morning.

Answer:

The answer is 300

Step-by-step explanation:

so first you do 100% of 400 which is 400 then you do 400 divided by 4 because it is counted from 25%, 50%, 75%, and 100%.

after that when u get the answer for 400 divided by 4 which is 100 you do 100 times 3 which is 300.

hope this helps :D

Answer:

75% of 400 is 300. Equation- (75×400) ÷ 100=300 (Im not sure what the model is because it was not included in this question but hopefully this helped solve the first part of your question.)

Step-by-step explanation:

Multiple 75*400

You would get 30,000, then take that 30,000 and divide it by 100

You get 300, which is the answer for the first part of the question.

Step-by-step explanation:

if you mean x multiply 2 :

j(x) = 2x + 1

j(a+1) = 2(a+1) + 1

= 2a+ 2 +1

=2a + 3

if you mean x to the power of 2

j(x) = x^2 +1

j(a+1) = (a+1)^2 + 1

= a^2 + 2a + 1 +1

= a^2 + 2a + 2

Answer: The domain is 3/7, -6, and 4.

Step-by-step explanation:

In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.

As the other answer mentioned, x = -6 and x = 4 are not in the domain, since they both make the denominator equal to zero, and thus the overall expression undefined. But x = 3/7 is allowed, since f (3/7) = 0.

Every other real number is also acceptable.

In interval notation, the domain is then

[tex](-\infty,-6) \cup (-6,4) \cup (4, \infty)[/tex]

Answer:

x = -36

Step-by-step explanation:

x/3+7=-5

Subtract 7 from each side

x/3+7-7=-5-7

x/3 = -12

Multiply each side by 3

x/3*3 = -12*3

x = -36

Answer:

A

Step-by-step explanation:

[tex]\frac{x}{3}[/tex] + 7 = - 5 ( multiply through by 3 to clear the fraction )

x + 21 = - 15 ( subtract 21 from both sides )

x = - 36 → A

An image is always formed at the back of a mirror. Thus, the appropriate option is D. -8.75 m. The flagpole is 8.75 m tall.

Let the angle of depression from Madelyn's point of view be represented by θ. Then applying the required trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

          = [tex]\frac{1.65}{1.7}[/tex]

Tan θ = 0.9706

θ = [tex]Tan^{-1}[/tex] 0.9706

  = [tex]44.2^{o}[/tex]

θ = [tex]44.2^{o}[/tex]

Let the height of the flag be represented by h. And for a given mirror, the angle of incidence is equal to that of reflection. Then;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

         = [tex]\frac{h}{8.75}[/tex]

0.9706 = [tex]\frac{h}{8.75}[/tex]

h = 0.9706 x 8.75

  = 8.49275

h = 8.5 m

Since the image is formed at the back of the mirror, then the flagpole is 8.5 m.

Therefore the appropriate answer is option D. -8.75 m

Answer:

Step-by-step explanation:

since AB and BC are perpendicular so AB.BC=0, (scalar product)

AB=(-4, -6), and BC=(xc+2, yc-8)

AB.BC= -4x-8-6y+48 =0

so the equation of BC is 2x+3y-20=0

C is on the line BC, so 2xc+3yc-20=0, but yc=0, so xc=20/2=10

AB and CD are parallel, so det(AB, CD)=0

AB and AD are perpendicular so AB.AD=0

AB=(-4, -6) and CD =(x-10, y), AD= (x-2, y-14)

det(AB, CD)=0

             x-10-y = 0 equivalent to  x-y = -10

AB.AD=0

 -4x+8-6y+84=0  equivalent to   2x+3y=44

let's solve

x-y = -10

2x+3y=44

-5y = -64, y = 64/5, x= -10+64/5=14/5
