Answer:
X = 100
Step-by-step explanation:
- In proportion questions, they want you to multiply one of the sides by a variable, (i usually represent it with K) and then change the proportion sign to an equal.
- This is because proportional means they have a ratio between them, with one side increasing by "k" for each increase in the other side.
- Multiply the left by k, so
- we know that y= 5, for x = 36, so sub this in the equation
- simplify
- re-arrange for k, <u>k = 5*6 = 30</u>
- now we know k, we can create the real equation,
- sub in 3 as y
- <u>x = 100</u>
Answer:
see below
Step-by-step explanation:
Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.
If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:
A' = (1/2)A = (1/2)(8, 4) = (4, 2)
