Y = 3x
x(3) = y
1) (-2) 3 = -6
2) (-1) 3 = -3
3) (0) 3 = 0
4) (1) 3 = 3
-6, -3, 0, and 3 respectively.
<u>Answer:</u>
243 students are involved in either sports or music whereas 100 are not
involved in either of it.
<u>Step-by-step explanation:</u>
No. of students who are in music = 115
No. of students who are in sports = 197
No. of students who are in both activities = 69
So, no. of students who are involved either in sports or music,
= (115 + 197 - 69)
=243
So, no. of students who are not involved in either sports or music,
= (343 - 243)
=100
if you're solving for x it's -30
steps: x/-3+20=30
first subtract 20 from both sides then you'll have
x/-3=10 then multiply both sides with -3
you should have x by itself and -30 on the other side
answer x=-30
Answer:
A. 3, 4, 5
Step-by-step explanation:
Option A:
LHS = 3² + 4² = 9 + 16 = 25
RHS = 5² = 25
(3, 4, 5) is a right triangle.
Option B:
LHS = 7² + 8² = 49 + 64 = 113
RHS = 9² = 81
(7, 8, 9) is NOT a right triangle.
Option C:
LHS = 3² + 9² = 9 + 81 = 90
RHS = √95² = 95
(3, 9, √95) is NOT a right triangle.
The answer is most likely (c).
