Find the slope of the line through the given pair of points, if possible. Based on the slope, indicate whether the line through the points rises from left to right, falls from left to right, is horizontal, or is vertical. (-7, -9) and (-5, -8)

Graph the system of inequalities. 2x – y ≤ -8x + 4y ≥ -16

Solve the equation by factoring x2 + 3x =40 Write equation in factored form equal to zero: x =

Find the product and write the result in standard form. (9 + 8i)(6 – 6i)

Factor out the GCF from the polynomial. 24x6y + 21xy4

Factor the trinomial completely. If the polynomial cannot be factored, write “prime.” Choose the one correct factor. x2 – 7x – 30

Find the product. (x + 10)(4x – 8)

Solve the linear inequality. Other than ∅, use interval notation to express the solution set. -8x + 6 ≤ -2(3x – 7)

Add or subtract. Assume all variables represent positive real numbers.

Evaluate the expression. -82
