A quadratic equation has the general form
of: <span>
y=ax² + bx + c
It can be converted to the vertex form in order
to determine the vertex of the parabola. It has the standard form of:
y = a(x+h)² - k
This can be done by completing a square. The steps are as follows:
</span><span>y = 3x2 + 9x – 18
</span>y = 3(x2 <span>+ 3x) – 18
</span>y + 27/4= 3(x2 <span>+ 3x+ 9/4) – 18
</span>y = 3(x2 + 3/2)^2 – 99<span>/4
</span>
Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
Answer:
375
Step-by-step explanation:
500 x 0.25 = 125
500 - 125 = 375

1 hour = 6 pages
So,
5 hours = 6×5
ㅤㅤㅤㅤ= 30 pages
therefore, She writes 30 pages in 5 hours.
Answer:
6f
Step-by-step explanation:
i said this because x is 6 by itself it will be 6 and just f and that's equals means 6f
