Answer: A

Step-by-step explanation: A, because it by the end of all of this, (A) manages to reach to the top, and B stretches across the chart/ which is considered the distance. Also if you look where the points are, you can see that point A rose quicker in shorter time.

Step-by-step explanation:

We find determinant for the given matrix and set it equal to -1

To find determinant we apply formula

$|A| = a_{11}(a_{22}a_{33} − a_{32}a_{23}) - a_{12}(a_{21}a_{33} − a_{31}a_{23})+a_{13}(a_{21}a_{32} - a_{31}a_{22})$

$|A| = x(1x - 2) - 0(7-7) + 0(14-7x)$

|A| = x^2 - 2x

Now we set the determinant = -1

$x^2 - 2x=-1$

Add 1 on both sides

$x^2 - 2x + 1=0$

Now factor it

(x-1)(x-1) = 0

Set each factor =0 and solve for x

x- 1=0 so x=1

The first rule you need to know is

$(a^b)^c=a^{bc}$

So, you have

$\dfrac{(x^{25})^{-6}}{(x^{-3})^{48}}=\dfrac{x^{25\cdot(-6)}}{x^{-3\cdot 48}}=\dfrac{x^{-150}}{x^{-144}}$

The second rule you need to know is

$\dfrac{a^b}{a^c}=a^{b-c}$

So, you have

$\dfrac{x^{-150}}{x^{-144}}=x^{-150-(-144)}=x^{-150+144}=x^{-6}$

Line AB contains points A(3,-2) and B(1,8). the slope of line AB is?

ipn [44]

The slope of a line is $\frac{y_2 - y_1}{x_2 - x_1}$ . We have the points (3, -2) and (1, 8). Let's substitute those into the formula.
$\frac{8 - (-2)}{1-3}$
subtracting a negative is the same as adding, so that makes our equation
$\frac{8+2}{1-3}$
$\frac{10}{-2}$
slope = -5

The graph of f(x) = |x| is transformed to g(x) = [X + 11-7. On which interval is the function decreasing?

puteri [66]

Answer:

The interval of the decreasing function is (-∞ , -1) ⇒ g(x)

The interval of the decreasing function is (-∞ , 0) ⇒ f(x)

Step-by-step explanation:

* Lets explain how to solve it

- Decreasing function means a function with a graph that moves

downward as it is followed from left to right.

- For example, any line with a negative slope is decreasing function

- Lets look to the attached graph to understand the meaning of the

decreasing function

∵ f(x) = IxI ⇒ green graph

∵ g(x) = Ix + 1I - 7 ⇒ purple graph

- From the graph f(x) translated 1 unit to the left and 7 units down to

form g(x)

- The domains of f(x) and g(x) are all real numbers {x : x ∈ R}

- The range of f(x) is {y : y ≥ 0}

- The range of g(x) is {y : y ≥ -7}

# For f(x)

- The slope of the green line from (-∞ , 0) is negative

- The slope of the green line from (0 , ∞) is positive

# For g(x)

- The slope of the purple line from (-∞ , -1) is negative

- The slope of the purple line from (-1 , ∞) is positive

∵ The line with negative slope represent decreasing function

∴ The interval of the decreasing function is (-∞ , -1) ⇒ g(x)

∴ The interval of the decreasing function is (-∞ , 0) ⇒ f(x)
