Answer:

a = 9 + 6

Step-by-step explanation:

The subtraction equation we are given is a - 9 = 6

To get a version with the addition sign that means the same thing, all we have to do is to add 9 to both sides of the equals to sign.

<em>This is because whenever you want to add an arbitrary value to cancel out figures in an equation, you have to perform such an operation to both sides of the equation so that the equation will still remain balanced.</em>

This will give us.

a - 9 + 9 = 6 + 9

<em>from this, we can see that -9 + 9 = 0</em>

Hence, a = 6 + 9

This equation above means the same thing as the first.

2x - 3 = 11
2x = 14
x = 7

Using this value, The answers would be the following:
A. 23/21 (assuming you are dividing 2 by 3x; if you multiplied 2/3 by x, the answer would then be 17/3)

Which function is represented by the graph? f(x) = –|x| 4 f(x) = –|x| – 4 f(x) = –|x 4| f(x) = –|x – 4|.
exis [7]

The function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

f(x)=-|x-4|

<h3>What is a graph of function?</h3>

The linear function has the highest power of the unknown variable one. Thus, the graph plotted for the linear function is a straight line.

Types of function movement over the graph -

  • Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.
  • Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph b units down and by replacing parent function with f(x)+cshifts the graph b units up.

The graph given in the problem is attached below. All the parents function of the options are absolute function.

In the graph, the parent function 4 units shifted to right. So the -4 should add in the parent function. Thus, by the above definition, this is a horizontal shift of the function and can be written as,

f(x)=-|x-4|

Hence, the function which is represented by the graph attached below shifted 4 units right is similar to option d, which is,

f(x)=-|x-4|

Here is a list of numbers.
max2010maxim [7]

Answer:

-0.3, -0.12, -0.03, 0.15

Step-by-step explanation:

-0.3 is the least because 0.3 = 0.30 and 0.30 is greater than 0.12, -0.12 is the second one because it is 0.12 behind 0 and is greater than -0.03. 0.15 is the last one because it is the only positive number therefore is the greatest one.

really hope this helps and isn't confusing but I'm pretty sure this is correct!

A jar contains 10 ounces of gumdrops, 3 ounces of licorice bits, and 3 ounces of jelly beans. How many more ounces of jelly bean
Andrew [12]

Answer:

10 jelly beans.

Step-by-step explanation:

Let x be ounces of jelly beans.

We have been given that a jar contains 10 ounces of gumdrops, 3 ounces of licorice bits, and 3 ounces of jelly beans.

To make weight of jelly beans be 50% of total assortment, we will add x ounces of jelly beans to 3 so that it will be 50% of total assortment plus x. We can represent this information in an equation as:

3+x=\frac{50}{100}(10+3+3+x)

Let us solve for x.

3+x=0.50(16+x)

3+x=8+0.5x

3-3+x=8-3+0.5x

x=5+0.5x

x-0.5x=5+0.5x-0.5x

0.5x=5

\frac{0.5x}{0.5}=\frac{5}{0.5}

x=10

Therefore, 10 jelly beans must be added to make the assortment 50 percent jelly beans in weight.

Let us cross check our answer.

\frac{3+10}{3+3+10+10}=\frac{13}{26}=0.5=50\%
