A line has a slop of 2 and passes through the point -12,8

Answers

Answer 1
Answer: The function of the line would be best represented by y=mx+b where m = slope and b = y intercept.
To find this we can put it into the slope-intercept form of y-y1=m(x-x1)

Which is:
y-8=2(x+12)
y=2x+24+8
y=2x+32
Hope that helps!
Answer 2
Answer: y=mx+b
m=slope
b=y intercept

slope=2
y=2x+b
solve for b by inputing
(-12,8)
(x,y)
x=-12 and y=8 is one solution
input -12 for x and 8 for y

8=2(-12)+b
8=-24+b
add 24 to both sides
32=b

y=2x+32

A model of a rectangular table for a dollhouse is 13 inches long and 8 inches wide. The original table is 52 inches long and 32 inches wide. are the model table and the original table similar figures?

Answers

Hi there, to find if they are similar figures, we have to find if they are the same ratio (fractions). 52 inches and 13 inches equal 52/13, 52÷3=4, the original table is 4 times longer than the model. Now, we have to figure out the width, 32/8 is also 4 because 32÷8=4. The original table is also 4 times wider than the model. So, the two tables are similar.

What is the difference between discrete and continuous data? (Bar charts)

Answers


Discrete data
This data set shows a group of discrete data.
This is called discrete data because the units of measurement (for example, CDs) cannot be split up; there is nothing between 1 CD and 2 CDs.

Continuous data
The data set shows a group of continuous data.
This data is called continuous because the scale of measurement - distance - has meaning at all points between the numbers given, eg we can travel a distance of 1.2 and 1.85 and even 1.632 miles.
Continuous data can be shown on a number line, and all points on the line have meaning and are different, but with discrete data only certain values have meaning.

Y=4x+rx+6 solve for x

Answers

y=4x+rx+6 

y-6=4x+rx    Subtract \ 6 \ from \ both \ sides 

y-6=x(4+r)    Factor \ out \ the \ common \ term \ x 

(y-6)/(4+r) =x   Divide \ both \ sides \ by \ 4+r
