Answer:

<em>r = 6 </em>

Step-by-step explanation:

4r + 6r - 13 = 7r + 5

10r - 13 = 7r + 5

10r - 7r = 13 + 5

3r = 18

hi there! here's my answer for you...

Answer:

r = 6

Step-by-step explanation:

4r + 6r - 13 = 7r + 5

10r - 13 = 7r + 5

10r - 13 + 13 = 7r + 5 + 13

10r = 7r + 18

10r - 7r = 7r + 18 - 7r

3r = 18

3r/3 = 18/3

r = 6

<em>hope this helped. have a good one!</em>

Which equation is shown in the graph?
Gekata [30.6K]
Hmmmm judging by the values in between integers, like 2.5, 1.5, -2.5, -3.5 and so on, those values always produce a smaller number hmm that sounds whack... lemme put it differently.

a floor() function, namely ⌊x⌋ like that, will floor the decimal values, so ⌊2.5⌋ floors to 2, because 2.5 is between 2 and 3, and the smallest is 2, the "floor", the 3 will be the "ceiling".

so for a floor function, ⌊1.5⌋ is 1, 1.5 is between 1 and 2, 1 is the smallest, ⌊-3.5⌋ is -4, recall that on the negative side, the closer to 0, the larger, so -1 is much larger than -1000.

and say ⌊-1.35⌋ is -2, -1.35 is between -2 an -1 and -2 is the smallest, the "floor".

that said

x = 2.5      ⌊ 2.5 + 3⌋ is ⌊5.5⌋ which is 5

x = 1.5      ⌊ 1.5 + 3 ⌋ is ⌊4.5⌋ which is 4

x = -2.749   ⌊ -2.749 + 3⌋ is ⌊0.251⌋ which is 0

anyway and so on, so you can pretty much see is the floor function of ⌊ x + 3⌋.
