5 3/4
5 remainder 3
Is the mixed number
While it does sounds redundant, it could be a "part to whole" ratio
Answer:
1) 2
2) -2
Step-by-step explanation:
1)
x - 5 = -3
Add 5 to both sides
x = 2
2)
3 - 2x = x + 9
Add 2x to both sides.
3 = 3x + 9
Subtract 9 from both sides
-6 = 3x
Divide both sides by 3
-2 = x
x = -2
Hope this helps you understand! :D
The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3
Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)
I'm assuming it's 10^6, so 10 would be the base, and 6 would be the exponent.
