Y² + 14y + 49 = 0
We know a² + 2ab + b² = (a + b)²
(y)² + 2 x 7 x y + (7)² = 0
(y + 7)² = 0
y = -7
y = -7
Correct option C
Answer:
see below
Step-by-step explanation:
a) 1/7 is the smallest, so a is in the correct t location.
b) is 1/3, which is larger than 1/4
c) is 2/10 or 1/5, which is smaller than 1/4
so on the graph, b and c are backwards. c should be to the right of 1/4, and b should be to the left.
Answer:mark is 7. Mike is 4
Step-by-step explanation:x+y=11. Y=2x-10 thus substituting for y in equation1 we have x+2x-10=11. 3x-10=11. 3x=11+10. 3x=21. X=21/3. X=7. Mike =(2×7)-10=14-10=4
Step-by-step explanation:
- 5^-2= 1/25 (as when taken up 25 it becomes 5^-2).
- 2^5= 32 (when we multiply 2 for 5 times, we get 32).(2×2×2×2×2)
- 2^-4=1/16 (as when we take up 16 we get 2^-4)
- 5^3=125 (when we multiply 5 for 3 times we get 125)(5×5×5)
