Answer- A-16
Because when doing completing the square, you divide the coefficient of x by 2, which is 4, and the square it which is 16
Answer:
Step-by-step explanation:
-16-16v - v = 10v + 4
Add 16 to both sides and combine like terms giving you
15v = 10v + 20
Subtract 10v from both sides
5v= 20
Divide by 5
V=4
Square D because 2/8 are not shaded. 2/8=1/4 and 1/4=25%
Answer:
The solution is (3,13) and (-1,-3). So none of the mentioned options is correct.
Step-by-step explanation:
Given that


Now, by susbstituting the value of 'y' from equation i to equation ii, we get






Now by factorization, equation iii can be written as



x = 3 and x = -1
By putting the values of x in equation i, we get
y = 4(3) + 1
y = 12 +1
y = 13
and
y = 4(-1) + 1
y = -4 +1
y = -3
Therefore, the solution is (3,13) and (-1,-3). So none of the mentioned options is correct.
