F(x) = -2/3x+ 2; find f(-3)

Step-by-step explanation:

f(-3) = -2/3(-3) + 2

             2 + 2 = 4

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.

answer: qc and de are congruent
