Aug 10, 2018 · See explanation below (x,y) is a pair of real numbers. The meaning is: (x,y) is an ordered pair of numbers belonging to RRxxRR=RR^2. The first pair memeber belongs to the first set RR and the second belongs to second RR. Althoug in this case is the same set RR. Could be in other cases RRxxZZ or QQxxRR (x,y) has the meaning of an aplication from RR to RR in which to every element x, the ...

Aug 6, 2015 · The easiest way in which you can solve this system of equations is to add the two equations to get the value of #x#. More specifically, you add the left side of the equations and the right side of the equations separately. #{(x+y = 10), (x-y = 8) :}# #x + color(red)cancelcolor(black)(y) + x - color(red)cancelcolor(black)(y) = 10 + 8#

The range of a function is its y-values or outputs. If you look at the graph from lowest point to highest point, that will be the range. Ex: #y = x^2# has a range of y #>=# 0 since the vertex is the lowest point, and it lies at (0,0). Ex: y = 2x + 1 has a range from #-\infty# to #\infty# since the ends of the graph point in those directions ...

Feb 24, 2016 · x=7 and y=9 Just add the two linear equations x+y=16 and x−y=−2 This gives us x+y+x-y=16-2 or 2x=14 i.e. x=7.

Mar 9, 2016 · y intercept at (0,0) and slope of -1/1 The equation y=-x can be written in slope intercept form as y=-1/1x+0 making the y intercept at (0,0) and the slope -1/1 Begin by graphing the y intercept at the origin (0,0) and then use the slope down 1 for -1 and over 1 to map the remaining points.

Mar 30, 2017 · xy product is where you multiply things. So if you multiply x and y, they become xy. Algebra . Science ...

Apr 25, 2018 · 3(x-y) The difference of x and y states subtraction. x-y The difference must be 3 times that 3(x-y)

Dec 14, 2016 · See tally-mark like graph and explanation. x>0 to make ln x real. The x-intercept ( y = 0 ) is 1. At x= o, y takes the indeterminate form 0 X (-oo) Yet, the limit is 0. since x approaches 0 at a faster rate than ln x approaches 0, as x to 0_+.

Feb 10, 2015 · Since 3x - 4y = -12 is linear, the easiest place to start is to draw the line for that equation by determining the x and y axii intercepts. When y = 0 then 3x - 4y = -12 becomes 3x = -12 or x = -4 When x = 0 then 3x - 4y = -12 becomes -4y = -12 or y = 3 We can now draw the line for the equation 3x - 4y = -12 by drawing a straight line through the two points (-4,0) and (0,3) All that remains is ...
