1-18+25
if u subtract first the answer would be 8
if u add first it would be 42
the order of operations is necessary otherwise we would get different and wrong answers
Answer: The required scale factor![=\dfrac43](https://tex.z-dn.net/?f=%3D%5Cdfrac43)
Step-by-step explanation:
Formula : ![\text{Scale factor }=\dfrac{\text{Side in image}}{\text{Corresponding side in pre-image}}](https://tex.z-dn.net/?f=%5Ctext%7BScale%20factor%20%7D%3D%5Cdfrac%7B%5Ctext%7BSide%20in%20image%7D%7D%7B%5Ctext%7BCorresponding%20side%20in%20pre-image%7D%7D)
Here, ED = 3 units in Δ DEF which corresponding to SR = 4 units in ΔRST
Now,
Scale factor for the given transformation = ![\dfrac{SR}{ED}](https://tex.z-dn.net/?f=%5Cdfrac%7BSR%7D%7BED%7D)
![=\dfrac{4}{3}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B4%7D%7B3%7D)
hence, the required scale factor![=\dfrac43](https://tex.z-dn.net/?f=%3D%5Cdfrac43)
Answer:
D
Step-by-step explanation:
Since James gave Malcolm a head start of 20 feet, Malcolm's line should start at 20 feet. So that rules out A. They were obviously going further so they went more feet, So C is ruled out because it shows them not moving, plus James didn't get a 15 foot head start which is what the C graph shows. Finally it's not B because if you look at the key at the bottom of every graph, it says that Malcolm is the dotted line, and B shows James getting a 20 foot head start, not Malcolm.
Hope this helps!
