The equation 10x - 15x + 5 = -45 + 40 can be simplified to -5x + 5 = -5. By moving the numbers to one side, it becomes -5x = -10, to 5x = 10, then x = 2.
This website can't print plus signs in the questions. I'll assume that's 40 - 5x - 5 + x - 8 That simplifies to 27 - 4x if that's what you wanted to do.
f(x) = x2 + 5x + 6At a critical point, f'(x) = 0.f'(x) = 2x + 5 = 02x = -5x = -2.5f(-2.5) = (-2.5)2 + 5(-2.5) + 6 = (6.25) - (7.5) + (6) = 4.75
The variables have no known values and as an expression it is: 5x+9y+5
5x.40
5x+10=40 5x+10-10=40-10 5x=30 5x/5=30/5 x=6
5x+8y = 40 8y = -5x+40 y = -5/8x+5 in slope intercept form
5(x=8)

5
well its impossible to answer since there is no x=? if it was 5x+20=40 then x=4 5 x 4=20+20=40
x2 + 13x + 40 = x2 + 5x + 8x + 40 = x(x + 5) + 8(x + 5) = (x + 8)(x + 5)
(x + 5)(x + 8)

10x - 15x + 5 = -45 + 40Combine like terms:-5x + 5 = -5Get the x term alone (subtract 5 from both sides):-5x = -10Divide both sides by -5x = 2
f(x) = x2 + 5x + 6At a critical point, f'(x) = 0.f'(x) = 2x + 5 = 02x = -5x = -2.5f(-2.5) = (-2.5)2 + 5(-2.5) + 6 = (6.25) - (7.5) + (6) = 4.75
It is an algebraic expression that can be simplified to: 11x+5
