Step-by-step explanation:
Calculate length of OA, OB and AB seperately.
There should be 2 wit the same lengths for it to be an isosceles ∆
First we take the two points (-7,5) and (-5,9).
Compute the slope:

Then the linear relation may be in the following form

Since the point (-7,5) is on the line, then

The relation is then

.
We check that the other point are on the above line:

W
e have then a linear relation.
Answer:
4/115
64/62
Step-by-step explanation:
Since you dont have to simplify, just find the number of each animal then put it over whatever other animal the questions said was treated
To answer the question, let x be the number of children who went to the concert and y the number of adults. The equations that would best illustrate the descriptions are,
x + y = 630
2x + 5y = 2910
Solving for x and y gives an answer of x = 80 and y = 550. Therefore, 80 children went to the said concert.
