Step-by-step explanation:

Prove ∠RQS = ∠RTS

Two triangles are said to be congruent if all the three sides and three angles of one triangle is equal to the three sides and three angles of another triangle.

Statement                            Reason

QS ≅ TS                               Given

RS ≅ RS                               Reflexive property of congruence.      

R is the midpoint of QT       Given

QR = RT                                R is the midpoint of QT. Therefore by

                                             definition, QR = RT.

ΔRQS = ΔRTS                       Side-side-side triangle congruence theorem. If

                                             three sides of one triangle is equal to three

                                             sides of another triangle, then both triangles

                                             are congruent to each other.

∠RQS = ∠RTS                        Corresponding angles of congruent triangles

                                              are equal.

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
