If f(x) = 3x²+2 and g(x)=x2-9, find (f- g)(x).

Mathematics
1 answer:
Solnce55 [7]2 years ago

Answer:

Step-by-step explanation:

Depending on whether or not the g(x) is x^2 or 2x, I have both ways.

If g(x) is x^2 - 9...

--> (3x^2 + 2) - (x^2 - 9) = 2x^2 + 11

If g(x) is 2x...

--> (3x^2 + 2) - (2x - 9) = 3x^2 - 2x + 11

Hope this helps!

Answer:

y = 4

Step-by-step explanation:

Note that A and B have the same x-coordinate:  1.  This means that AB is a vertical line through x = 1.  The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5.  Thus, it's just y = 4.

Review:  y = 4 bisects AB and represents a horizontal line.

What is the distance between (-5, 5) and (1, -2)
Murrr4er [49]

Answer:

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

Step-by-step explanation:

          We will use the distance formula to solve.

\displaystyle d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2}

\displaystyle d=\sqrt{(1--5)^2 +(-2-5)^2}

\displaystyle d=\sqrt{(6)^2 +(-7)^2}

\displaystyle d=\sqrt{36+49}

\displaystyle d=\sqrt{85}\text{, or about 9.22 units}

A factory uses 1/6 of a barrel of raisins in each batch of granola bars. Yesterday, the factory used 1/2 of a barrel of raisins.
balu736 [363]

1/6 = 1 batch, 2/6 = 2 batches and so on

if the factory used 1/2, the factory used 3/6 of a barrel, which equals to 3 batches.

<em>hope it helps :)</em>
