An elephant is as strong as how many horses?

Answer:

x = -12

Step-by-step explanation:

-6x - 73 = 12x + 143

Add 6x to each side

-6x+6x - 73 = 12x+6x + 143

-73 = 18x+143

Subtract 143 from each side

-73-143 = 18x+143-143

-216 = 18x

Divide by 18

-216/18 =18x/18

-12 =x

System of Linear Equations entered :

[1] y - 2x/3 = -1

[2] y + x = 4

// To remove fractions, multiply equations by their respective LCD

Multiply equation [1] by 3

// Equations now take the shape:

[1] 3y - 2x = -3

[2] y + x = 4

Graphic Representation of the Equations :

-2x + 3y = -3 x + y = 4

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -y + 4

// Plug this in for variable x in equation [1]

[1] 3y - 2•(-y +4) = -3

[1] 5y = 5

// Solve equation [1] for the variable y

[1] 5y = 5

[1] y = 1

// By now we know this much :

y = 1

x = -y+4

// Use the y value to solve for x

x = -(1)+4 = 3

Bisection is a process that produces two equal parts of angles or lines. Thus applying the bisection principle, the measure of angle lmn = [tex]168^{o}[/tex]

This question deals with sub-bisection of angles. Bisection is the method required to divide a given angle or line into two equal parts.

From the given question:  m<rmp = [tex]21^{o}[/tex]     (given)

But,

m<qmp = m<rmp + m<qmr = 2 x m<rmp      (addition property of bisected angles)

            = 2 x [tex]21^{o}[/tex]

m<qmp = [tex]42^{o}[/tex]

Also,

m<lmp = m<lmq + m<qmp = 2 x m<qmp      (addition property of bisected angles)

            = 2 x [tex]42^{o}[/tex]

m<lmp  = [tex]84^{o}[/tex]

Then,

m<lmn = m<lmp + m<pmn  = 2 x m<lmp (addition property of bisected angles)

           = 2 x [tex]84^{o}[/tex]

m<lmn = [tex]168^{o}[/tex]

Thus, the measure of angle lmn is [tex]168^{o}[/tex].

Answer:

Domain: [-5, 5)

Range: (1, 3]

Brackets and parenthesis are important! Make sure to put them in the correct spot

Step-by-step explanation:

Domain is which x values the line hits. It hits from -5 to 5 but doesn't include 5 as indicated by the open circle.

Range is which y values the line hits. It hits from 1 to 3 but doesn't include 1 because, again, there is an open circle.

When a number is not included, you put it with a parenthesis.

When it is included, you put it with a bracket.

Answer:

C

Step-by-step explanation:

We want to determine the vertex of the quadratic equation:

[tex]\displaystyle y = -x^2 + 2x + 1[/tex]

Recall that the vertex is given by the formulas:

[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In this case, a = -1, b = 2, and c = 1.

Determine the x-coordinate of the vertex:

[tex]\displaystyle x = -\frac{(2)}{2(-1)} = 1[/tex]

To determine the y-coordinate, evaluate the function at x = 1:

[tex]\displaystyle \begin{aligned} y(1)&= -(1)^2 + 2(1) + 1 \\ &= 2\end{aligned}[/tex]

In conclusion, the vertex of the quadratic equation is (1, 2).

Hence, our answer is C.

Rate of change is the slope.

The slope is the change in Y over the change in X:

Slope = (5- -3) / (2 - -2)

Slope = 8/4

Slope = 2

Answer: A.2

Answer:

x = 12 degrees

y = 50 degrees

Step-by-step explanation:

3x + 144 = 180

3x = 180 -144

3x = 36

x = 12 degrees

Let the angle to the left of 2y-5 be z:

z + 95 = 180

z = 85 degree

z + 2y - 5 = 180

85 + 2y - 5 = 180

2y = 180 - 85 + 5

2y = 100

y = 50 degree

Step-by-step explanation:

the side length = [tex]\sqrt{105}[/tex]

Consider perfect squares either side of 105 , that is

100 < 105 < 121 , then

[tex]\sqrt{100}[/tex] < [tex]\sqrt{105[/tex] < [tex]\sqrt{121}[/tex] , so

Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x  = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)²  = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11

Frequency tables are used to show the number of occurrence of each data in a dataset.

The complete frequency table is as follows:

[tex]\begin{array}{cc}{Trick}&{Years}\\52&0&53&1&54&2&55&1&56&2\end{array}\right][/tex]

The given data are:

54, 56, 53, 54, 56, 55

To complete the frequency table, we simply count each data element and the number of occurrence (i.e. the frequency).

So, we have:

52 has a frequency of 0

53 has a frequency of 1

54 has a frequency of 2

55 has a frequency of 1

56 has a frequency of 2

So, the complete frequency table is:

First step is to put all the same ones together

( FYI, xy and yx is the same thing, just like how

2 x 3 and 3 x 2 is the same thing) this time I'll bracket the groups to make it easier on the eyes

(x^2 +x^2) + (xy - xy) +( y^2 + y^2) + (yz - yz) +

(z^2 +z^2) + (zx - zx)

2x^2 + 2y^2 + 2z^2

All the others just cancel themselves out, for example, xy-xy

Answer:

for question 4, 1/3 is the probability since there are 6 sides and there are two numbers on a die less than 3, 2 and 1.

2 and 1 are 2 of the 6 numbers on the die.

so 2/6

but we have to simplify!

divide 2 by 2 and 6 by 2

1/3 done!

Step-by-step explanation:

Explanation:

The set of outcomes we want to happen is {1,2}. These items are less than 3. We have A = 2 outcomes here.

There are B = 6 total outcomes in the set {1,2,3,4,5,6} which are values on a standard cube.

The probability we want is A/B = 2/6 = 1/3

The reason why the information in the diagram is enough to determine that ΔLMN ≅ ΔPON using a rotation about point N and a dilation is;

C: because one pair of congruent corresponding angles is sufficient to determine similar triangles

From the attached diagram, we observe that angles NOP and NML are congruent to each other, thus, we can write that;

∠NOP ≅ ∠NML

Now, since corresponding angles of both triangles LMN and PON are congruent it means we can say that both triangles are indeed similar triangles.

Thus, we can conclude that one pair of congruent corresponding angles

is sufficient to determine similar triangles.
