What is the length of PR?
A. 7
B. 8
C. 6
D. 9

C

Step-by-step explanation:

The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

20PR = 120 ( divide both sides by 20 )

PR = 6 → C

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
