Answer:

$S=\left \{ 0\:or\:6 \right \}$

Step-by-step explanation:

Absolute value equation has one property that explains why we'll have two solutions for that equation:

$|a|=-b \Rightarrow a=-b\:and\:a=b$

$3|v-3|=9$

Dividing by three to simplify it:

$3|v-3|=9\\\frac{3|v-3|}{3}=\frac{9}{3}\Rightarrow |v-3|=3\\|v-3|=3\\$

Applying that property over here, the absolute value is equal to one value and its symmetrical one. Notice that when we take the bars out v-3=3 and v-3=-3.

$v-3=-3\Rightarrow v=-3+3\Rightarrow v=0\\v-3=3\Rightarrow v=3+3 \Rightarrow v=6\\S=\left \{ 0\:or\:6 \right \}$

The table shows the input and output of a function Table(input:3,4,6,11. Output:5,7,11,21) (a) Explain what makes this set of da

JulijaS [17]

Ans(a):

We know that a function can't have repeated x-values.

In given table we see that there i no repeating x-value. That's why the given table represents function.

Ans(b):

We know that a function can't have repeated x-values.

So if in given table we see any repeating x-value then that may cause the given data set to not be a function.

like if we have 3, 4, 3, 11 in the input then it will not be a function.

Ans(c):

we can use two points say (3,5) and (4,7) to find the linear equation of the form y=mx+b

slope is given by

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{7-5}{4-3}=2$

Noow plug value of m=2 and any point say (3,5) into y=mx+b

5=2(3)+b

5=6+b

-1=b

now plug m=2 and b=-1 in y=mx+b, we get y=2x-1

Hence required equation in function notation can be written as

f(x)=2x-1.

Now to prove that above function is correct, we just graph the given points from table and the obtained function.

We see that points lie on the grpah of f(x)=2x-1.

Which proves that our equation is correct.

What is the average of -2.6, 1.8, -3.3, -2.7, 2.2 ?<br> I dont understand this.

olya-2409 [2.1K]

Average = Mean

To find the mean, add up the numbers and divide it by how many numbers there are.

So, $-2.6+1.8+(-3.3)+(-2.7)+2.2=-4.6$

There are 5 numbers in total.

$-4.6 \div 5=-0.92$

To do these types of division, ignore the decimal and add a 0 at the end.

So we can do:
$-460\div5=-92$

And put back the decimal.
Hope this helps :)

Using the graph, choose the correct formula for the function g.

serious [3.7K]

The graph scale is 0.5.
g(x) is 3 units lower than f(x). How do we find this?
A isn't correct because then g(x) would be 1 <em>above</em> f(x).
C isn't correct either because that would mean that g(x) is f(x) moved 1 over to the left.
D isn't correct because that would mean g(x) is f(x) moved 3 to the right.
B is correct because it means that g(x) is f(x) moved down 3 units.
I got B, but it is always helpful to double check work. Hope this helps!

Jessica wants to calculate her grade in her accounting class.she has four test grades (82, 65, 71, and 77) and a homework grade

Aleks04 [339]

To solve the problem, get the percentage of each test by multiplying the score and the percentage then add it all up:

82 * .25 (highest test grade) + 65* .15 (lowest test grade) + 71*.20 (each test remaining) + 77*.20 (each test remaining) + 92*.20 (homework grade)

= 20.5 + 9.75 + 14.2 + 15.4 + 18.4 = 78.25 or 78% in whole number
