I think this is the Domain. Since a domain is a group of numbers that can be entered in a function to create a valid output. They are set of all possible values of x which will satisfy a ffunction and output real y-values
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.
A wildlife conservationist has is own strategies to monitor every animals that are arrived in there quarter or center before the animals are went back to its natural habitat. So 72 of the armadillos are tag went to the wild but then again 78 is captured again and record that 15 of them are tag. So there is 53 of them still has no tag. The best estimate would be 135
Answer:
2/3
Step-by-step explanation:
4/9+2/9=6/9
then you have to reduce/simply your answer more from 6/9
divide each number by 3 and that with give you your answer 2/3.
6÷3=2 and 9÷3=3
Adding fractions with same denominator
