well that depends is it (-11,-10) and (-1,-4) or is it (-1,-11) (-4,-10) either way I'll solve the slope for both. so the first way with (-11,-10) (-1,-4) is to subtract the two y's over the two x's so -10--4/-11--1 which equals -10+4/-11+1 which equals -6/-10 and when you reduce you get 3/5 then the second ex. would be -4--11/-1--10 = -4+11/-1+10 = 6/9 reduce to 2/3.
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
4... if you plug it in, it works
654326. Or 154326. or something else.
3-1=2 4-2=2 2+3-4+1=2 3-2+1=2
x + y = -4x - y = 2x - y = 2x + y - y = 2 + yx = 2 + yx + y = -42 + y + y = -42 + 2y = -42 - 2 + 2y = -4 - 22y = -62y/2 = -6/2y = -3x = 2 + yx = 2 - 3x = -1The solution of the system is (-1, -3)
-(4-3) -(1) -1
(5 + 4 - 3 - 2) x 1 = 4
4 + 4 +1
5 + (-4) = 1 x = -4
x equals 4 over 35
6(n - 4)(n + 1) n = 4, -1
Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
This gives us the equations: n = xy = yx x != y (Note that for this example, the != stands for not equal to similar to some programming languages.) xy always equals yx due to the communtative property of multiplication. So there are actually an infinite number of answers. Some are given below: 6 = (2)(3) = (3)(2), 2 != 3 12 = (3)(4) = (4)(3), 3 != 4
-2a + 5 = 1 -2a = -5 + 1 -2a = -4 a = -4/-2 a = 2
If: 2a+13 = 5a+1 Then: a = 4
