c. 9
To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.





multiply number of pants and number of shoes
18 * 16 = 288 combinations
For this case we have the following function:
y = 1/4 (x + 2) ^ 2 - 7
We derive the equation:
y '= 1/2 (x + 2)
Equaling zero we have:
1/2 (x + 2) = 0
We clear the value of x:
x + 2 = 0
x = -2
Answer:
The equation of the axis of symmetry for the parabola is:
x = -2
Answer: John:£800
Rachel:£1600
Step-by-step explanation:
Since John and Rachel shared £2400 in the ratio 2:4, it means that £2400 was equal to(2+4) units, which is 6 units.
Thus, each unit is £2400/6= £400
Hence, John got £400x2=£800, and Rachel got £400x4=1600.
Hope u understand my solution. :)
