10. Given f(x) = 3x2 – 3x + 5 and g(x) = -7x + 4, find (f - g)(x).
A. 3x2 - 10x + 9
B. 3x2 + 4x + 9
C. 3x2 - 10x + 1
D. 3x2 + 4x + 1

Answers

Answer 1

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= (3x² - 3x + 5) - (-7x + 4)

= 3x² - 3x + 5 + 7x - 4

= 3x² + 4x + 1. (D)

The graph of y = 4x2 - 4x – 1 is show
Use the graph to find estimates for
the solutions of
i) 4x2 - 4x – 1 = 0

Answers

Answer:

Here we have the equation:

y = 4*x^2 - 4*x - 1

And we should have the graph (you can see it below this answer)

Now we want to find the solutions of:

4*x^2 - 4*x - 1 = 0

These solutions will be the two values of x at which the graph of our function intersects the line y = 0, that is the x-axis.

Then we need to find the two values of x at which our graph intersects the x-axis.

In the graph, we can estimate the solutions as:

x = -0.2

x = 1.2

To find the exact solutions we can use the Bhaskara's equation, and we will find that the solutions are given by:

[tex]x = \frac{-(-4) +- \sqrt{(-4)^2 - 4*4*(-1)} }{2*4} = \frac{4+ -\sqrt{32} }{8} = \frac{4 +-5.66}{8}[/tex]

Then the two solutions are:

x = (4 + 5.66)/8 = 11.2075

x = (4 - 5.66)/8 = -0.2075

The perimeter of the first rectangle below is 120 inches. The perimeter of the second rectangle is 180 inches. What are the values of x and v?

A. x = 6; v = 42
B. x = 13; v = 42
C. x = 42; v = 6
D. x = 48; v = 28

Answers

Answer:

A

Step-by-step explanation:

Answer:

A. x = 6; v = 42

Step-by-step explanation:

Strategy : Guess and Check

Let's start with A:

If x = 6, then the first rectangle would be 12 + 42 + 6  + 12 + 42 + 6 = 120

Let's see if this checks out with the second rectangle.

6 + 42 + 42 +  6 + 42 + 42 = 180

Step-by-step explanation:

I took the flvs test

The action to make both side balanced

Take away 5 blocks from the left side.

What is Balanced?

In science, if an object is still, we say it is balanced. An object is in an equilibrium state when it is balanced. Any forces acting on the object are counterbalanced by forces moving the other way. The average location of the gravitational pull on an object is known as the centre of gravity.

We have the figure.

On right side there are total 8 weights.

and, on left there are total 3 weights.

So, the difference of blocks on

= 8- 3

= 5 blocks

So, take away 5 blocks from left.
