The preimage is the solid triangle while the image is the dashed triangle. Recall that any transformation takes a preimage and maps it to an image. The "preimage" is the "before"; while the "image" is the "after"
Preimage ---> Image
Before ---> After
The "pre" is one way to help remember it means "before".
-------------------------
The preimage has a horizontal segment length of 15 units (count from x=-9 to x=6 and you should count out 15 spaces). The corresponding horizontal piece on the dashed triangle is only 3 units long. Divide the image length over the preimage length
(image length)/(preimage length) = 3/15 = 1/5 = 0.2
Now if the figure wasn't reflected over the point (6,6), then the final answer would be either 1/5 or 0.2; however, this reflection does happen so we need to make the scale factor negative. So we go from 1/5 to -1/5, and we go from 0.2 to -0.2
---------------------------------------------
Final Answer as a fraction: -1/5
Final Answer in decimal form: -0.2
Answer:
y=6x-6
Step-by-step explanation:
i think not sure tho
Divide the total portion (9 1/2 cups) by the portion size (3/4 cup).
=9 1/2 ÷ 3/4
convert 9 1/2 to improper fraction
=19/2 ÷ 3/4
to divide fractions, multiply by the reciprocal/inverse of 3/4
=19/2 * 4/3
multiply numerators; multiply denominators
=(19*4)/(2*3)
=76/6
=12.666666

Hope this helps! :)
70 miles x
————— = ———-
1 hour 14 hours
Cross multiply.
70 • 14 = x
980 = x
