a triangle with three congruent sides

Question 9: right angles

Answer:

angles that measure 90 degrees

Question 10: inequalities

Answer:

represents in these 4 signs:

x>2= x is greater than 2 x<1= x is less than -1 x_>2= x is greater or = to 2 x_<-1= x is less than or = to -1

Ex: (solve) 4a + 6> 2a + 10

answer: a>2

Ex: solve for z. -4z/2 -3>4z

answer: z>-1/2

Question 11: diameter of a circle

Answer:

rise over run

Ex: (0,2)(6,5) what is the slope?

slope= change in y/ change in x slope= 5-2/6-0= 3/6= 1/2

Ex: find intercept ~plug in 1 set of coordinates

y= 1/2x+b 2=1/2 X 0=b. 2=b

Question 23: quadratic expression

Answer:

contains (^2) variables, if not then its a linear expression. To factor use reverse FOIL

Ex: factor x^2-4x-2

(x+3)(x-7)
