Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.
Answer:
What's a Solution to a System of Linear Equations? Note: If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.

Answer:
x squared
Step-by-step explanation:
x exponent 4 can be written like this:
x*x*x*x
*=multiply
you can then divide it by x 3 times and... ye.
If you think my answer is good can you maybe give me brainliest? I am trying to achieve virtuoso rank.
Answer:
Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2
2x^2 + 3x - 20 = 0
(x + 4)(2x - 5) = 0
Solution:
x = -4
x = 5/2
