expressions equations and inequalities
solve
5x-2x-3 ≤ 9
x ≤ 4
what is the shape of the graph of the equation y=3.5-.5x
straight line
cube root of 125
5
convert to standard form
3x^2+4x^5+7X^3=y
y=4x^5+7x^3+3x^2
factor
(x+2)(x-3)
x^2-x-6
when solding an inequality, when do you switch then inequality sign
when dividing by a negative number

1
square root of 1000
100
define vertex
the curve in a parabola
solve
x^2+9x+6
x=-3
solve
3y+9 > 12
y > 1
convery the equation 3.5-.5x=y to standard form

cube root of 27
3
vertex form
a(x-h)^2+k
simplify, factor, then solve
x^2-2+3x-2x+8
x={-1, -6}
when do you use an open circle when putting an inequality on a number line? when do you use a closed circle?
closed when greter then/less then or equal to, open when only equal to or less then
