Answer:

Step-by-step explanation:

The usual English meanings of the words "reduction" and "enlargement" apply to geometrical figures.

Figure A'B'C'D' is smaller than figure ABCD, so represents a reduction.

__

Every coordinate of every image point is half as far from the origin in A'B'C'D' as in the original figure ABCD. For example, the x-coordinate of C' is 2, and the x-coordinae of C is 4. The dilation factor is the ratio of these values:

  k = Cx'/Cx = 2/4 = 1/2

The scale factor is 1/2.

Answer:

7 trees.

Step-by-step explanation:

Number < 7 ft consists of the first 2 stems:

5 || 8   - 1 tree

6|| 2,3,7,8,9,9  -  6 trees

= 1 + 6

= 7.

The number of trees that are less than 7 trees as shown in the stem-and0leaf plot is: 7 trees.

In a stem-and-leaf plot, data points are represented in leaves and stems. For example, representing height of trees as 5 || 8, means a data point representing a height of a tree measuring 5 ft and 8 inches tall.

From the stem-and-leaf plot given, the data points that are below 7 feet are 7 in number, which range from 6 ft and 9 inches down to 5 ft and 8 inches.

The answer is: 7 trees.

Answer:

A

Step-by-step explanation:

If we start from top to bottom all we have to do is check which ones are not equal.

The first one is

[tex]a^2(b+c) = a^3(\frac{b}{a}+c)[/tex]
If we multiply is out we get

[tex]a^2b+a^2c = a^3*\frac{b}{a}+a^3c\\\text{which turns into}\\a^2b+a^2c=a^2b+a^3c[/tex]

That is NOT equal to the other. Making the answer A.

Answer:

D.

Step-by-step explanation:

1) the required probability can be calculated as sum of two probabilities:

P=p1+p2, where p1 - when the 1st attempt is correct, p2 - when the 2d attempt is correct;

2) p1=1/10; p2=1/9, then the required probability:

P=1/10 + 1/9 ≈ 1/5.

The correct table of values, graph the function and use the graph to estimate the sales 1 .... 12 weeks after release is,

t             s = 12 √4t + 10

1                    34

2                   43.94  

3                   51.56

4                   58

5                   63.66

6                   68.78

7                   73.49  

8                   77.88

9                   82

10                  85.89

11                   89.59

12                  93.13

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The sales of a certain product after an initial release can be found by the equation,

⇒ s = 12 √4t + 10

where s represents the total sales (in thousands) and t represents the time in weeks after release.

Here, The equation is,

⇒ s = 12 √4t + 10

where, s represents the total sales (in thousands) and t represents the time in weeks after release.

We put t=1,2,3,.....,12 and create a table

t             s = 12 √4t + 10

1                    34

2                   43.94  

3                   51.56

Answer:

x=4 (Vertical angles have to be equal to each other! If one side is 46 then the side vertical to it is 46!) **Plug number in for x to verify once again!**

Step-by-step explanation:

You need to understand vertical angles!!

Vertical Angles must be congruent and equal to each other!

You need to do:

10x+6=46

Subtract 6 from both sides

10x=40

Do 40 divided by 10

x=4

To verify: plug 4 for x which should be 40 added to 6 is 46!

Step-by-step explanation:

Here,

Base(b) =9

Opposite/Perpendicular (p)= x

Hypotenus (h) = 24

We know,

(p)^2 = (h)^2 - (b)^2

(x)^2 = (24)^2 - (9)^2

x^2 = 576 - 81

x^2 = 495

x = root under 495

C is the hypotenuse, or longest side of the triangle (24).

A is the one length we have besides the hypotenuse(9).

b = 22.2486

Answer:

Answer:

The graph of a linear equation is a straight line.  The "solution" to a system of two linear equations is the point where the two lines cross.  If the two lines are parallel, they never cross; hence parallel lines have no solution.  Two lines are parallel if they have the same slope (the m value in y = mx+b).  One of your equations is y = -2x + (you left the y-intercept out).  The slope is -2.  So any line with a slope of m = -2 will be parallel to this line and will not cross it.  The second line also needs a different value of b, the y-intercept.  Otherwise it is the same line and every point is a solution.  So if your equation is:

y = -2x + 1

Then any equation of the form y = -2x + b, b≠1 will create a system with no solution.  Hence the values of m and b are m = -2, b ≠ 1.

As is often the case with multiple choice questions, you only need to find part of a correct answer to be able to make the right choice.

The number line picture shows the left-most point has a value less than -1. That means the numerator of its negative fraction will be greater than the denominator. The only fraction like that on the list is -4/3, and the only answer choice with that listed first is choice D.

Answer:

x = -4

Step-by-step explanation:

x+y = -10       or     y = -10 - x

substitute this into the second equation

x      -    y    = 2

x      -  (-10-x) = 2

2x + 10 = 2

2x = -8

x = - 4
