A has the coordinates (–4, 3) and B has the coordinates (4, 4). If DO,1/2(x, y) is a dilation of △ABC, what is true about the im

age △A'B'C'? Check all that apply.
AB is parallel to A'B'.

DO,1/2(x, y) = (1/2x, 1/2y)

The distance from A' to the origin is half the distance from A to the origin.

The vertices of the image are farther from the origin than those of the pre-image.

A'B' is greater than AB.

A dilation is a transformation D_{o,k}(x,y), with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P'. The center O is a fixed point, P' is the image of P, points O, P and P' are on the same line.

In a dilation of D_{o, \frac{1}{2} }(x,y), the scale factor, \frac{1}{2} is mapping the original figure to the image in such a way that the distances from O to the vertices of the image are half the distances from O to the original figure. Also the size of the image is half the size of the original figure.

Therefore, <span>If D_{o, \frac{1}{2} }(x,y) is a dilation of △ABC, the truth about the image △A'B'C'</span> are:

<span>AB is parallel to A'B'.

D_{o, \frac{1}{2} }(x,y)=( \frac{1}{2}x,  \frac{1}{2}y)

The distance from A' to the origin is half the distance from A to the origin.</span>

How do you solve 6) n2+7n+15=5 by factoring?
charle [14.2K]
First, you need to set the equation equal to zero:

n^2 + 7n + 10 = 0

Now we factor. We need to find two numbers that add up to 7 and multiply to 10. 

2 + 5 = 7
2 * 5 = 10

Now, we just need to write this as a polynomial:

(n + 2) (n + 5)
is our answer. 

Hope this helps!

the line y=2x-4 is dilated bt a scale factor of 3/2 and centered at the origin. Write an equation that represent that image of t
Veseljchak [2.6K]

Answer:  y = 2x -6

Step-by-step explanation:

Since, If (x,y) represents the coordinates of a line, then after dilation about the origin by the scale factor k, the coordinates of the resultant line will get by the rule,

(x,y)\rightarrow (kx,ky)

Here, The equation of the given line is,

y = 2x - 4

x-intercept and y-intercept of the line are (2,0) and (0,-4) respectively,

Hence, the line y = 2x - 4 will be passes through the points (2,0) and (0,-4),

By the above property,

The dilated line about the origin will be passes through the points (3,0) and (0,-6),   ( Because (3/2× 2, 3/2×0) = (3,0) and (3/2×0, 3/2×-4) = (0,-6) )

Hence, the equation of transformed line after dilation,

y-0 = \frac{-6-0}{0-3}(x-3)    

y-0=2(x-3)

y-0=2x-6

y=2x-6

10.) Kelly is flying a kite to which the angle of elevation is
jarptica [38.1K]

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

sin70 =  \frac{h}{l}  \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.

If -3( x+2)-5=x-(6+x),what is the value of 1/3-x?
Mariana [72]

<u><em /></u>

Answer:

The value of x is -5/3.

The value of 1/3 - x is 2.

Step-by-step explanation:

-3( x+2)-5=x-(6+x)          Distribute

-3x + -6 - 5 = x - 6 - x      Combine llike terms

-3x + -11    = -6              <em><u>POSITIVE AND NEGATIVE IS NEGATIVE</u></em>

      -3x -11 =  -6              Add 11 on both sides

            -3x = 5            Isolate the variable by dividing -3 on both sides

              x  =  -5/3

1/3 - x

= 1/3 - -5/3   <u><em> </em></u><u><em>NEGATIVE AND NEGATIVE IS POSITIVE</em></u>

= 1/3 + 5/3

= 6/3

<em>= 2</em>

<em>You must isolate the variable in order to solve equations with variables. </em>

<em> </em>

<em>Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on </em><u><em>ONLY </em></u><em>one side of the equation. </em>

<em> </em>
