Hint: Classifications are Real, irrational, natural, whole, integer
It is Both a Real & Irrational Number
What is the Solution?
-4x - 8 = -7x - 35
-4x - 8 + 8 = -7x -35 +8
-4x + 7x = -7x + 7x - 27
(3x)/3 = -27/3
x = -9
Find the equation that passes through point (2, 4) with the slope of -1
y = -x + 6
What is (f + g) (x) if
f(x) = x + 4
and
g(x) = 3x - 2
(f + g)(x) = 4x + 2
What is the factor?
x2 - 4
(x - 2) * (x + 2)
Is this number rational or irrational and why?
0.3033033303333…
It is an Irrational number. The 3's do not repeat in a pattern.
Solve the equation?
4(x - 3)- 2x = -2(x - 2)
4(x - 3)- 2x = 2(x - 2)
4x - 12 - 2x = 2x - 4
2x - 12 + 4 = -2x + 4 - 4
2x - 2x - 8 = 2x - 2x
-8 = 0
NO SOLUTION
The Line AB passes through points (9, 4) and (6, 3) and the Line CD passes through points (3, -2) and (7, -14). What is their relation to each other?
Parallel/Perpendicular/Neither
AB and CD are perpendicular to each other.
AB Slope = 1/3
CD Slope = -3
What is (f - g)(x) if:
f(x) = -2x2 + 4x - 3
g(x) = 6x2 + 3x - 5
(f - g)(x) = -8x2 + x + 2
Solve the equation.
x - 23x + 132
Factored
(x - 11) * (x - 12)
x - 11 =0
x - 12 = 0
x = 11 & x = 12
