Which equation could be used to find the value of x

A 39x-11=17x+6
B 39x-11=2(17x+6)
C 2(39x-11)=17x+6
D 2(39x-11)=2(17x+6)

Answer:

k=0

Step-by-step explanation:

/2-5K+3=4

We move all terms to the left:

/2-5K+3-(4)=0

determiningTheFunctionDomain

-5K+3-4+/2=0

We add all the numbers together, and all the variables

-5K-1+/2=0

We multiply all the terms by the denominator

-5K*2-1*2+=0

We add all the numbers together, and all the variables

-5K*2=0

Wy multiply elements

-10K=0

K=0/-10

K=0

Answer:

all the angles in a triangle will add to 180

65 + 57 + 2x = 180

subtract the 65 and 57 from both sides

2x = 58

x = 29

D) 29

hope this helps :)

Step-by-step explanation:

Answer: x=29

Step-by-step explanation:

In a triangle, the sum of the measures of all angles is 180 degrees.

Therefore, we can add up all the angles in this triangle, setting them equal to 180:

65+57+2x=180

Using the equation above, solve for x:

Simplify:

122+2x=180

Subtract 122 from both sides:

(122+2x)-122=180-122

Simplify:

2x=58

Divide both sides by 2:

2x/2=58/2

Simplify:

x=29

For the two similar figures, the expression can be written as:

[tex]\dfrac{GH}{AB} = \dfrac{JD}{CD}[/tex]

In geometry, similarity refers to the property of two figures that have the same shape but possibly different sizes. Two figures are considered similar if their corresponding angles are congruent and their corresponding sides are proportional.

For example, two triangles are similar if they have the same shape but can be different in size. This means that the corresponding angles of the two triangles are equal and the corresponding sides are in proportion.

The symbol used to denote similarity is "~". For example, if triangle ABC is similar to triangle DEF, we write it as:

ABCDE~GHJDF are similar. So the ratios of the sides of the figure can be written as,

[tex]\dfrac{GH}{AB} = \dfrac{JD}{CD}[/tex]

Answer:

Step-by-step explanation:

ΔBCD is isosceles, so ∠CDB = ∠CBD = x. The sum of angles in the triangle is 180°, so you have ...

  x + x + 50° = 180°

  2x = 130° . . . . . . . . . subtract 50°, collect terms

  x = 65° . . . . . . . divide by 2

__

Triangle ABC is also isosceles, so ∠BAC = ∠BCA = y. Angle ABC is the supplement of angle x. The sum of angles in ΔABC is 180°:

  y + y + (180° -x) = 180°

  2y - 65° = 0 . . . . . . . . . . subtract 180°, substitute the value of x

  y -32.5° = 0 . . . . . . . divide by 2

  y = 32.5° . . . . . . . . . . add 32.5°

Answer:

A. parabola I believe that is the answer

Answer:

If any point on AB, then x = a. Hence, the equation of a straight line parallel to y-axis at a distance a from it is x = a.

Step-by-step explanation:

Thus, if P(x, y) is any point on AB, then x = a. Hence, the equation of a straight line parallel to y-axis at a distance a from it is x = a. The equation of y-axis is x = 0, since, y-axis is a parallel to itself at a distance 0 from it.

Answer: Choice A) Jada should have multiplied both sides by 108.

Reasoning:

x is a placeholder for some unknown value. We are dividing x by 108 to form the fraction x/108. To isolate x, we need to undo this operation. So we need to multiply both sides by 108. Doing so leads to the solution x = -48.

Answer:

By hypotenuse - side test (HL) the two triangles are congruent.

Step-by-step explanation:

In ∆ABC and ∆DCB

i) angleABC = angleDCB.....(each 90°)

ii) BC = BC .....( common side)

iii) AC = DB.....(given)

therefore by hypo-side test ∆ABC congruent ∆DCB

Answer:

HL

Step-by-step explanation:

∠B ≅ ∠C = 90°

AC =   DB                  {Given and they are hypotenuse}

BC = CB                     {Reflexive property}

ΔABC ≅ ΔDCB             {HL congruent}

Step-by-step explanation:

f(x) = x / (x - 7) = 1 + 7 / (x - 7).

The domain of f(x) depends whether the denominator of the rational expression is non-zero.

When (x - 7) = 0, x = 7.

Hence domain of f(x)

= All real values of x excluding 7. (C)

Answer:

C. All real values of sucth that x ≠ 7

This is the answer because:

1) Set up the composite function and evaluate, then find the domain of the result.

Answer:

B. 35

Step-by-step explanation:

The range of a set of numbers is the difference between the highest and lowest numbers in the set.

1. Find the highest and lowest numbers from the set. Arranging them from least to greatest can make this easier.

-15, -12, 6, 18, 20

The lowest number is -15 and the highest is 20.

2. Subtract these two numbers to find the range.

20 -- 15

Two minus signs like that make a positive, so it becomes an addition problem.

20 + 15 = 35

Answer is b.

Answer:

part a if that's what you mean

Step-by-step explanation:

Answer:

These triangles are not similar I think

Hi there! Let's solve this problem step by step.  :)

We have two triangles, QRP and XYP.  You're given a few values.

It is given that QR = 16.  QP = 6 + 18.  RP = 5 + 15.  Go ahead and add those.

QR = 16, QP = 24, RP = 20.  

Now XYP!

XY = 12.  YP = 15.  XP = 18.  

If you know the corresponding parts between these triangles--they should be QR to XY, QP to YP, and RP to XP.  Those are 16/12, 24/15, and 20/18.  Divide those.  

You get 1.3333, 1.6, and 1.1111.  Your turn! Are they similar?

[P.S., if you're confused about the AA/SAS/SSS similarity postulates, that just means the sides they have in common.  You're not given any angle measurements, so SAS (side angle side) is out.  SSS is possible, but since the ratios aren't equivalent, SSS is out.  Again, AA (angle-angle) isn't possible because you're not given any angle measurements.)

That's it! :)
