  Question 1
$$6x^2 = 5x + 4$$

Question 2
$$9x^2 = 25$$

Question 3
$$f(x) = -x^2 +8x - 12$$. Find the x-intercepts, y-intercept, vertex, range and domain.

Question 4
Simplify fully. $$3\sqrt{45} – 4\sqrt{80} =$$

Question 5
A cell phone company charges a monthly rate of $12.95 and$0.25 a minute per call. The bill for this month is $21.20. How many minutes were charged on this bill? Question 6 $$y = 2x^3 - 4$$. Solve for x. Question 7 Find the domain of the function $$f(x) = \frac{5}{x-2}$$. Question 8 Graph the function and find its range and domain. $$f(x) = \sqrt{2x+10} + 3$$ Question 9 Factorize completely. $$24x^7 + 8x^6 – 80x^5 =$$ Question 10 Natalie and her friend made money selling lemonade. Today, they combined their earnings and counted the total of$190. How much did each of them make if Natalie made \$40 more than her friend?

Question 11
Simplify.
A) $$4 - \sqrt{6^2 + 8^2} =$$
B) $$\frac{3}{10}(9 - \sqrt{4}) =$$

Question 12
Expand. $$(2x-4)(2x+4) =$$

Question 13
$$\frac{7}{2x - 10} - \frac{3}{x-5} =$$
