The right answer is C: (9-y²)/25 - y²/36 = 1
3v-5=d
In this case, v is proportional to d. Meaning that as you increase the value of v, then the value of d will change at a proportional rate. For example, if v was 1 then d would be -2. Then if v was 2 then d would be 1. If v was 3 then d would be 4. The value of d increases 3 for every increase in v. Does that help?
Answer:
A. 
Explanation:
Associate property of multiplication: a × (b × c) = (a × b) × c
Option A
Shows associate property of multiplication. Does not change final answer.
Option B
The grouping does not change inside the parenthesis.
Option C
This does show associate property but multiplying first 8 × 1/3 is complex.
Option D
Product of this changes the final answer. Not correct.
Answer:
(4x - 1)^2 = 16x^ - 8x + 1. This is a perfect square trinomial.
Step-by-step explanation:
Take a look at B: 4a^2 - 10 a + 25. The square roots of 4a^2 and 25 are 2a and 5 respectively. Does (2a - 5)^2 come out to 4a^2 - 10a + 25? No.
Take a look at C: 25b^2 - 5b + 10 We know this is not a perfect square trinomial because 10 is not a square.
D: 16x^2 - 8x + 1: both 16x^2 and 1 are perfect squares, so we have:
(4x - 1)^2 = 16x^ - 8x + 1. This is a perfect square trinomial.
