The value of x where the expression –4x – 8 will be equivalent to –9x –1 will be 7/13.

<h3>How to calculate the value?</h3>

It should be noted that we are simply to find the value of x where the expression –4x – 8 will be equivalent to –9x –1.

This will be:

= +4x - 8 = -9x - 1.

4x + 9x = -1 + 8

13x = 7

Divide

x = 7/13

The value is 7/13.

Which would you consider to be more accurate, a probability experiment of 10 trials or a probability experiment of 100 trials

Marat540 [252]

I would 100 because the more the trials means the more the results which means you get more of an accurate experiment then if you only did 10. Because since you have so many answers from all of the experiments you can conclude the correct answer from all of the experiments. I hope you get what I’m trying to say

You start at (5, 3). You move down 3 units and left 6 units. Where do you end?

raketka [301]

Answer:

(-1, 0)

Step-by-step explanation:

5 is the x value which is left and right, so you said u move left 6 units. Since the 5 is positive and left is negative; 5-6= -1. 3 is the y value which is up and down (vertical), so you said u move down 3 units, since the 3 is positive, when you move down that is negative; so 3-3=0.

Which of the following is the graph of f(x) = -0.5|x+3| -2?

Tcecarenko [31]

Answer:

The last graph

Step-by-step explanation:

We transform functions in the following ways:

multiplying the function by a number to stretch or shrink it
multiplying by a negative to flip the orientation of the function
adding/subtracting a value to the input x to shift it horizontally
adding/subtracting a value to the output (or outside the function operation) to shift it vertically or horizontally.

Looking at the equation we can see $f(x)=-0.5\left|x+3\right|-2$

Vertically shrunk by 0.5
Negative leading coefficient to flip the graph's orientation
Horizontal shift of the vertex of 3 units to the left from (0,-2) to (-3,-2)
Vertical shift of the vertex of 2 units downward (-3,0) to (-3,-2)

The last graph has vertex (-3,-2) and satisfies the the equation.
