What type of graph uses percents to display data?

It depends on the data type. if you want to show an increase or decrease in something, you want a LINE GRAPH. if you want to show the difference between more than one variable, i would use a BAR GRAPH.

What is the result of a dilation of scale factor 3 centered at the origin of the line 2y + 3x=10?? PLEASE HELP PLEASEEEEEEEEE

maks197457 [2]

Given:

The equation of a line is:

$2y+3x=10$

The line is dilated by factor 3.

To find:

The result of dilation.

Solution:

The equation of a line is:

$2y+3x=10$

For $x=0$ ,

$2y+3(0)=10$

$2y+0=10$

$y=\dfrac{10}{2}$

$y=5$

For $x=2$ ,

$2y+3(2)=10$

$2y+6=10$

$2y=10-6$

$2y=4$

Divide both sides by 2.

$y=\dfrac{4}{2}$

$y=2$

The given line passes through the two points A(0,5) and B(2,2).

If the line dilated by factor 3 with origin as center of dilation, then

$(x,y)\to (3x,3y)$

Using this rule, we get

$A(0,5)\to A'(3(0),3(5))$

$A(0,5)\to A'(0,15)$

Similarly,

$B(2,2)\to B'(3(2),3(2))$

$B(2,2)\to B'(6,6)$

The dilated line passes through the points A'(0,15) and B'(6,6). So, the equation of dilated line is:

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-15=\dfrac{6-15}{6-0}(x-0)$

$y-15=\dfrac{-9}{6}(x)$

$y-15=\dfrac{-3}{2}x$

Multiply both sides by 2.

$2(y-15)=-3x$

$2y-30=-3x$

$2y+3x=30$

Therefore, the equation of the line after the dilation is $2y+3x=30$ .

Evaluate f(x) = –x2 + 1 for x = –3. –9 4 –4 –8

Klio2033 [76]

Answer:

-63

Step-by-step explanation:

Write the problem as a mathematical expression.

$f(x)=-x^2+1$ $for$ $x =3-9$ $4-4-8$

Simplify 4−4−8 to substitute in f(x)=−x^2+1

Subtract 4 from 4

$0-8$

Subtract 8 from 0

$-8$

Replace the variable x with −

8 in the expression

$f(-8)=-(-8)^2+1$

Simplify

$f(-8)=-64+1$

$f(-8)=-63$

Answer = -63

If i had a question like: If y = 2x-3 find the value of y when x= 2

meriva

That's is depend from the author of the equation. But most time there is need to multiply value X into constant before.
In other words it look likes
y=2*x-3

There are 8 members of a basketball team . In their last game their mean points scored was 12 . Dom was their best player with 3

irina1246 [14]

The mean points of the team is the average points per game

Dom's claim is wrong

<h3>How to determine if Dom is right</h3>

The number of players in the team is:

n = 8

The mean score per game is:

Mean = 12

The mean of a dataset is calculated as:

$Mean = \frac{Total}n$

So, we have:

$12= \frac{Total}8$

Multiply both sides by 8

$Total = 96\\$

When Dom's point is removed, we have:

$Points = 96 - 33$

$Points = 63$

There are 7 players left.

So, the mean point is:

$Mean = \frac{63}7$

$Mean = 9$

The mean score is not 10.

Hence, Dom's claim is wrong
