x<=6 the first thing i do is make this x=6 this is a vertical line which you plot by drawing a line from the six up..this should be easy... next one is y>=1..y=1 wouldnt this be a horizontal...
stuck on getting set points to graph on inequalities with two signs in them we were taught to change the < or > to = first,then solve for x and y..so on this one x+y<=30 i would first...
2/x + 2/3=1 first i have to get a common denominator,yes? which would be 3x...so its 6/3x+2x/3x=1now i am lost
the problem is: (5x)^14(5x)^16 I know to add the 14 and 16 because the bases are the same.And I would get 5x^30. does the 5x stay in parenethese? My choices are (5x)^30 and 5x^30
Can I do anything with this? (a-3)^2
hi.. find the product of three consecutive integers whose product is 336 i did x (x+1) (x+2) =336 which is : x(x^+2x+x+2) =336 combine like terms..x(x^+3x+2)...
help me translate this into english please!! f(x)=4x^+2;find f(-1) what is this asking? i know that f(x) is the same as y,correct? what do they mean by "find f(-1) are they asking to...
I used the y/2 -y/1 over x/2-x/1 formula to determine the slope of : (2,5) abd (-3,-5) My answer is -10/5 The other one I would like to confirm is: (-2,-3) and (4,-9) for which I go -6/6
I plotted (0,-1),(3,5),(-1,-3) and determined that they were in fact Collinear...just want to doublecheck
In which quadrant does the point (-2,3) lie? I have Quadrant II
graph the linear equation: 3x -y=3 I did the tbar for this one and came up with x-(1,0) (-1,-6) (2,3) I plotted a straight line,so it appears ok? The other one was: 2x+3y=12 I did the...
This one is stumping me..I do not see how the ordered pair satifies both equations yet the book says it does. Order pair is (0,2) First equation: 3x-4y=8 3(0) -4(2) is -8 -8 doesnt equal...
hi, my answer isnt jiving...is it possible the issue is negative sign? the equation is: 3x-4y=8 then i take 0 for x and 2 for y what i did was : 3(0)-4(2) =8 ...
i keep doing this one over and over and i must be not setting it up correctly.help! quesiton:how many liters of a 15% salt solution must be added to 2 liters of a 30% salt solution to yield a...
hi...a chemist has a 12% acid solutions and a 24% acid solution how many liters of each should be mixed to get 16 liters of 21%..can you explain the proper equations? thanks
How many liters of 15% salt solution must be added to 2 liters of 30% salt solution to yield a solution that is 18%? I am setting it up as follows..is this correct? 15% (x )liters =.15x ...
rate x time equals distance my problem is: car a is traveling at 70mph car B is 50 miles behind car a in 2.5 hours..what rate is B traveling at?
