Answer:
B
Step-by-step explanation:
The solution is the point of intersection of the 2 lines
The lines intersect at (- 3, - 4 ), then
f(x) = g(x) has solution x = - 3
I believe that it is 2x^2+1x-2
Answer: it is d becaues that is the mode
Answer:
772.2
Step-by-step explanation:
Using the method of cross- product
•
=
⇒ ad = bc, thus
85.8 × 9 = 11 × 70.2 = 772.2
Answer:
The correct option is 3.
Step-by-step explanation:
The given equation is

It can be written as

Taking out the common factor form the parenthesis.

If an expression is defined as
then we add
to make it perfect square.
In the above equation b=6.
Add and subtract 3^2 in the parenthesis.



.... (1)
Add 32 on both sides.

The vertex from of a parabola is
.... (2)
If a>0, then k is minimum value at x=h.
From (1) and (2) in is clear that a=2, h=-3 and k=-32. It means the minimum value is -32 at x=-3.
The equation
reveals the minimum value for the given equation.
Therefore the correct option is 3.
