Answer:
All of the options are in standard form (ax+by=c). But none of the answers is an option. The correct answer is <u>x+4y=8.</u>
Step-by-step explanation:
The following screenshot is a graphing website to prove that the equation x+4y=8 passes through the points (4,1) and (20,-3).
I don’t know if the equation x+4y=8 is an option for you, because I don’t see it as an option to choose out of the four.
But I hope this helps and answers your question :)
Answer:
the scale factor k is between 0 and 1
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
A dilation with the larger image than initial figure is called an enlargement.
A dilation that the smaller image than initial figure is called a reduction.
- If the scale factor k is greater than 1, the image is an enlargement
- If the scale factor k is between 0 and 1, the image is a reduction
- If the scale factor k = 1, the figure and the image are congruent
Thus, if the image is smaller than the original figure, then the scale factor k is between 0 and 1.
Jones takes 8 hours , therefore in one hour he paints a fraction of 1/8
smith takes 6 hours, thus in one hour he paints a fraction of 1/6
When working together they paint a fraction of 7/24 in an hour.
After 2 hours they will have painted a fraction of (7/24) ×2 = 7/12
The remainder will be 5/12 which will be undertake by smith alone.
Smith will therefore take 5/12 ×6/1 = 2.5 hour or 2 hours 30 minutes
