Answer:3 7/8
Step-by-step explanation:A. I think you just want the answer not the explanation. :)
X + 5y + 2 - 7x + 5y + 2y - 7x
First collect like terms (the numbers that have the same letters after them):
x - 7x - 7x = -13x
5y + 5y + 2y = 12y
Then put these back into the expression:
2 - 13x + 12y
Answer:
Step-by-step explanation:
plug 3 into x
2(3)^2+(3)
2(9)+3
18+3
21
f(3)=21
B. A,C, and D all simplify to 5, 12, 13 which is a pythagorean triple
Answer:
1/9
Step-by-step explanation:
Probability = Expected outcome/Total outcome
From the given pi chart,
Total outcome = 360degrees (since the total angle in a circle is 360 degrees)
Since we to find the probability of scoring a 5, we can see that the angle when he scores a 5 is 40degrees, hence;
Expected outcome = 40degrees
Pr(scoring a 5) = 40/360
Pr(scoring a 5) = 1/9
Hence the probability of scoring a 5 is 1/9
