How to define distance along a line

Mathematics

Answer:

Well to start we use the distance formula

Step-by-step explanation:

The distance formula is \sqrt{(x_{2} -x_{1})^{2}+ (y_{2} -y_{1})^{2 }

It's very simple you just plug in the coordinates.

The first coordinates is the x1 and y1 and the second coordinates is x2 and y2.

If you have any questions feel free to ask in the comments - Mark

Choose the set of equivalent fractions that correctly uses the LCD for these fractions 3/4 and 1/6
valina [46]

Answer: 9/12, 2/12

Step-by-step explanation:

Start by writing multiples of 6 and 4

4: 4, 8, 12

6: 6, 12, 18

Did you see the multiple that both numbers have? Yup, it's 12. So that has to be your denominator for both fractions. This is because you have to have the <u>LEAST</u> COMMON Denominator (LCD). So both numbers have 12 in common as one of their multiples and, it's the least common one because there are no numbers that come before it that are common for both numbers. Now, you just have to change the denominators of both fractions into 12. To do that to 3/4, just multiply the top and bottom by 3 to get 9/12. To do that to 1/6, just multiply the top and bottom by 2 to get 2/12.  Hope this helps!

NOTE: REMEBER THAT WHATEVER YOU DO TO THE TOP OF A FRACTION, YOU HAVE TO DO IT TO THE BOTTOM TOO (AND VICE VERSA)

Substitution. (6 points) <br> 3x + 2y = 11 <br> y = 5x - 1<br><br> {show work}
nexus9112 [7]
3x+2y=11
y=5x-1

Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1

3x+10x-2=11
y=5x-1

13x=13
y=5x-1

Now substitute the x to find the y:
x=1
y=5-1=4

If a person's score on a questionnaire has been found to predict observed social skills, and the linear prediction rule uses a r
swat32

Answer: Predicted level of social skill will be 46

Step-by-step explanation:

For a linear regression; the general equation is in the form;

y = mx + c

Where is the predicted value or variable

m = slope or gradient (regression coefficient )

c = intercept which is constant (this is where the line of best for crosses the y-axis.

y = predicted value

x = independent variable

Given the following:

Regression coefficient (m)= 3

Regression constant (c)= 16

Score(x) = 10 (independent variable)

From:

y = mx + c

y = 3(10) + 16

y = 30 + 16

y = 46

Predicted level of social skill will be 46

Write an equation perpendicular to 5x+6y=18 that passes through the point (10,7)
JulsSmile [24]

Answer:

Step-by-step explanation:

6y = -5x + 18

y = -5/6x + 3

perp slope: 6/5

y - 7 = 6/5(x - 10)

y - 7 = 6/5x - 12

y = 6/5x - 5
