Answer:
B.
Step-by-step explanation:
"negative reciprocal slopes" means the lines are perpendicular, so they will always intersect.
Hence there will be exactly one solution.
The slope is -0.8 and all values of x are > -3
So its the last option.
First we have to find how many chose cat:
100-48-14-2= 36%. Because the whole thing is 100% and I removed all the other animals to find the percentage of cats chosen.
Then we want to know the number of classmates:
Cat= 36% of 50 people = 0.36 x 50=18
Fish= 14% of 50 people = 0.14 x 50= 7
Now we see the difference between them :
18-7=11 people
The answer is D which is 11.
Your answer is 1.291666666666667 not to sure if its right but i used the calculator and i'm being really lazy.
Answer:
{(1, 120), (2, 100), (3, 150), (4, 130)}. The set of all first elements is called the domain of the relation. The domain of W = {1, 2, 3, 4}.
