The effect that the change in scale has on what the graph suggests is C. The differences between the groups seems much less in Graph B.

It should be noted that graph simply means a diagram that's used to show the information about a data given.

Here, the effect that the change in scale has on what the graph suggests is that the differences between the groups seems much less in Graph B.

Therefore, the correct option is C.

If triangles AMN and ABC are similar, then

AM/AB = AN/AC

or

AM/(AM + MB) = AN/(AN + NC)

Check if this is true:

AM/AB = 21/(21 + 9) = 21/30 = 7/10

AN/AC = 14/(14 + 6) = 14/20 = 7/10

The angle at vertex A is common to both of the triangles.

Then by the side-angle-side (SAS) similarity theorem, the triangles are indeed similar.

Answer:

Option D - x = 3 3/5

Step-by-step explanation:

Lets make the left side into an improper fraction :

2 2/5 = 12/5

Now let's make both fraction into equivalent ones but with the same denominator :

2/3 = 10/15

12/5 = 36/15

Now we substitute the equivalent values back into the equation :

10/15 × x = 36/15

Now we multiply both sides by 15 to remove the denominators:

10 × x = 36

Now we divide both sides by 10 and simplify :

x = 36/10

x = 18/5

x = 3 3/5

So our answer will be Option D

Answer:   3(6a+5)

We can confirm this by distributing the 3 back in

3*6a = 18a

3*5 = 15

So 3(6a+5) = 3*6a+3*5 = 18a+15

The process of factoring polynomials like this is basically using the distributive property in reverse.

Answer:

3(6a + 5)

Step-by-step explanation:

1)  Find the Greatest Common Factor (GCF).

1 - What is the largest number that divides evenly into 18a and 15?

It is 3.

2 - What is the highest degree of a that divides evenly into 18a and 15.

It is 1, since a s not in every term.

3 - Multiplying the results above,

The GCF is 3.

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

3 (18a/3 + 15/3)

3)  Simplify each term in parentheses.

3(6a + 5)

The number of students in the school given the number of people that attended the dance is 128.

Percentage is the fraction of an amount that is usually expressed as a number out of hundred. The sign used to represent percentages is %.

Number of students = number of students at the dance / percentage that attended the dance

32 / 25%

32 / 0.25 = 128

Answer:

D(x=1).

Step-by-step explanation:

2(5x+8)=6x+20

10x+16=6x+20

10-6x+16=6x-6x+20

4x+16=20

4x+16-16=20-16

4x=4

4x/4=4/4

x=1

The solution to this equation is x = 1

Given the equation, we apply the distributive property.

2( 5x + 8 ) = 6x + 20

10x + 16 = 6x + 20

10x - 6x = 20 - 16

4x = 4

x = 4 ÷ 4

x = 1

Therefore, the value of this equation is x = 1

Answer:

21 * 2 = 42

21 + 2 = 23

Step-by-step explanation:

well I know that 6 * 7 = 42 so I’m assuming that’s correct

Then 11 + 12 = 23 it could be the answer I’m not positive for this one though.

The first one should be correct.

Answer:

b = 9

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20-b\\\frac{2}{3} b+5+b=20-b+b\\\frac{5}{3} b+5=20\\\frac{5}{3} b+5-5=20-5\\\frac{5}{3}b=15\\b= 15*\frac{3}{5} \\b= 9[/tex]

Answer:

[tex]b = 9[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20 - b[/tex]

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

[tex]\frac{2}{3} b + 5 - 5 = 20 - b - 5[/tex]

Simplify.

[tex]\frac{2}{3} b = 15 - b[/tex]

Add b to both sides.

[tex]\frac{2}{3} b + b = 15 - b + b[/tex]

Simplify.

[tex]\frac{2}{3} b + b = 15[/tex]

Multiply everything by 3 to remove the fractions.

[tex]3(\frac{2}{3}b+b) = 3(15)[/tex]

Simplify.

2b + 3b = 45

Simplify.

5b = 45

Divide 5 from both sides.

5b ÷ 5 = 45 ÷ 5

Simplify.

b = 9

Step-by-step explanation:

isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

Multiply part of the right side by - 4

2x = -4*1/4 + 4* 3x/4  + 4                             Combine

2x = - 1 + 3x + 4                                            Combine again

2x = 3 + 3x                                                    Subtract 3x both sides

2x - 3x = 3                                                     Combine

-x = 3                                                              Multiply by -1.

-1 * -x = - 1 * 3

x = - 3

Analyzing the quadratic functions, it is found that the correct option is D. The functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Looking at the graph, Function f has a minimum value of 1 at x = -3. Hence, the axis of symmetry is x = -3.

Function g has a minimum value of 6 at x = -3. Hence, the axis of symmetry is also x = -3.

Therefore, the functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Answer: c

Step-by-step explanation:

The required values on the graph, the solution is approximate x = -0.33.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

To solve this equation, we can begin by combining like terms on the left-hand side:

3x² - 6x - 4 - 2/x + 3 + 1 = 0

3x² - 6x - 2/x = -3

Next, we can factor out the x term:

x(3x - 2) - 2(3x - 2) = -3

(x - 2)(3x - 2) = -3

Since the equation is equal to -3, we can add 3 to both sides to get:

(x - 2)(3x - 2) + 3 = 0

We can then factor the left-hand side to get:

(x - 2)(3x - 2 + 3) = 0

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

This equation has two solutions: x = 2 and x = -1/3.

Approximating these values on the graph, we see that the solution is approximate x = -0.33.

#SPJ2

Answer:

Step-by-step explanation:

We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).

A line parallel to y=2x-1 will have the same slope, 2.

We can write y = 2x + b for the new line.  We need to find b.  We can use the given point in this equation and solve for b:

y = 2x + b

2 = 2(4) + b  for (4,2)

2 = 8 + b

x = -6

The parallel line to y=2x-1 that goes through point (4,2) is:

y = 2x-6

We are asked to write the equation of the line that passes through (4, 2) and is parallel to y=2x-1.

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

Since the slope of the given line is 2, the slope of the line parallel to this one is also 2.

y=2x+c

Where: 2 is the y-coordinate of the point, and 4 is the x-coordinate.

Now, substitute 2 for y and 4 for x:

[tex]\longmapsto\sf{2=2(4)+c}[/tex]

Simplify!

[tex]\longmapsto\sf{2=8+c}[/tex]

Subtract 8 from both sides of the equal sign:

[tex]\longmapsto\sf{2-8=c}[/tex]

Answer:

Angles of the isosceles triangle are 36°, 72° , 72°

Step-by-step explanation:

Vertex angle : Base angle = 1 : 2

Vertex angle = x

Base angle = 2x

Sum of all angles of a triangle = 180°

          x + 2x + 2x = 180°

                      5x = 180

                        x = 180 ÷ 5

                        x = 36°

2x = 2 *36 = 72°

Angles of the isosceles triangle are 36°, 72° , 72°
