No it isn't because 2/5=0.4
Answer:
Step-by-step explanation:
The problem here is that the question is not clear. In particular, what does "2)" mean?
Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.
Answer:
The width of the given rectangle is
units
Therefore
units
Step-by-step explanation:
GIven that the area of the rectangle is
and length is (x+3)
To find the width of the given rectangle
Area of the rectangle ![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
![w=\frac{A}{l}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7BA%7D%7Bl%7D)
![w=\frac{5x^3+19x^2+6x-18}{x+3}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B5x%5E3%2B19x%5E2%2B6x-18%7D%7Bx%2B3%7D)
Solving the equation by synthetic division
-3_| 5 19 6 -18
0 -15 -12 18
________________________
5 4 -6 0
Therefore 5x^2+4x-6=0
Therefore
units
Therefore the width of the given rectangle is
units
Answer: 2
