x = 171
Solve the equations
(x+2)^3
x = -8
Find the range of the function for the given domain
f(x)=3x+7 ; {-2, -2, 0, 1, 2}
{1, 4, 7, 10, 13}
Solve t=(F^3 + G)a for a.
t/F^3 + G
x+2>= 9
x>= 7
Solve the equations. Note if it has an identity or no solution.
-2(-x-12) = -2x-12
It is an identity
x= -9
f(x)= 2x^2 + 4x - 3
x = 13
Is this equation a function?
y = 2x+4
Yes
Solve: D = (s-q)/x for s

Solve for x
5x+2 < 4x-4
x< -6
Solve for x:
|-2x+1|=17
x= -8, 9
Find the range of the function
f(x)=5x - 4 ; {-2, -2, 0, 1, 2}
{-14, -9, -4, 1, 6}
f(x) = -|3x+12| + 8 ; {-2, -1, 0, 1, 2}
{2, -1, -4, -7, -10}
Solve for A.
BA + 8 = 3m
A = 3m - 8 / B
Solve |x+2|>=9
x<= -11 or x>= 7
Whats the mistake?
f(x) = -2(x+3)<4x - 7
1. f(x) = -2x +6 <4x - 7
2. f(x) = -2x < 4x - 1
3. f(x) = -6x < -1
4. f(x) = x< 1/6
Step 4: incorrect inequality symbol
Round to the nearest thousandth
f(x) = (sqrt(x) -19) / 3x for f(2)
Approx -2.931
Find the range of f(x)= 9x/(x^2 -9) for f(-2)
Round to nearest tenth

Solve for u.
uw+uv = t
u = t/v+w
Solve:
-|6-3x| - 6>-12
x = 0 and x = 4
Solve for x
-2(-3x-2)-5x+3 = -2
x = -9
Evaluate:
f(x) = 3x^2 + 16 ; {-4, -2, 0, 2, 4}
{64, 28, 16, 28, 64}
Solve for range with the given domain.
