10x + -9 = 59can be rewritten as10x - 9 = 59add 9 to both sides10x = 68divide both sides by 10x = 6.8
You find x. Oh! There it is!! ^ See?

You only need to find the vertex of a parabola, so I assume this is the equation. Y = X^2 - 10X + 25 set to 0 X^2 - 10X + 25 = 0 now, you need to complete the square. Halve the linear term (-10), square it and add that to both sides. subtract 25 from each side to start X^2 - 10X = - 25 X^2 - 10X + 25 = - 25 + 25 factor left; gather like terms right (X - 5)^2 = 0 Vertex (5,0)
10x + 13 = 1710x = 17-1310x = 4x = 4/10x = 0.4
y = 10x
y = kx: 10 = 37k so k = 10/37 and y = 10x/37
10x - 30 10(x - 3) ------------
400x gives the smallest field of view. The magnification of the instrument, and the field of view are inversely rational.

10x + -9 = 59can be rewritten as10x - 9 = 59add 9 to both sides10x = 68divide both sides by 10x = 6.8
10x - 5x + 5x = 10x

If you mean: -10x+4-10x+5 then it is 9-20x when simplified
Y = 10x 10x = 40 y = 40
10x + 3 = 15 10x = 15 - 3 10x = 12 x = 1.2
