The first photo
Step-by-step explanation:
Its a i think
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.
The factors of 32 is 1,2,4,8,16, and 32.
Answer:
9-49
a= 2r+ 7
b= 2.5x + 16
c= 3r-2x-8.8

Answer:
9 cups
Step-by-step explanation:
Since every 6 cups have 7 1/2 gallons, you would divide 7 1/2 gallons by cups which gets you 1.25 as an answer. After you have found out that, then you would divide all 4 of those answers by 11 1/4 gallons, and if your answer is 1.25, well then that is your answer to the question, so it would be 9 cups in this case.
