For these types of algebra problems, you're trying to get whatever they tell you by itself on one side of the equals sign, meaning that you have to move everything else over by adding/subtracting or whatever else.

In this problem you have to get s by itself. All you do is just subtract 4r from both sides to get:

-2 - 4r = s

Because there are 2 variables/unknowns (s and r) you have no way of actually solving this problem without having a 2nd equation or something. So thats all you can do

D= V(x2 - 1)2 + (12 - y1)?
Mrac [35]

Answer:

The approximate length of segment EF is 7 unit  

Step-by-step explanation:

Given figure is the graph having E and F coordinate

The coordinate of point E = ( x_1 , y_1 ) = ( - 2 , -4 )

The coordinate of point F = ( x_2 , y_2 ) = ( 2 , 2 )

Let The distance between the points E and F = D

So, D = \sqrt{(x_2 - x_1)^{2} + ( y_2 - y_1 )^{2} }

or,  D = \sqrt{(2 - (- 2 ))^{2} + ( 2 - ( - 4 ))^{2} }

Or,  D = \sqrt{( 4 )^{2} + ( 6 )^{2} }

or, D = \sqrt{16 + 36}

∴  D = \sqrt{52}

I.e D = 7.21 unit

So, Approximate value of D = 7 unit

Hence The approximate length of segment EF is 7 unit  . Answer

Which answer is the equation of the line represented in function notation?
algol [13]

That has a y intercept at y=-1.   For every one block to the right we go three blocks up, so that's a slope of 3/1=3.    So in slope-intercept form our equation is

y = 3 x - 1

Answer: third choice
