Answer 1

Answer:

23.

Step-by-step explanation:

2y(3y-5) -2(y-5) -35

At y= -2

=2×-2(3×-2 -5) -2(-2-5) -35

=-4(-11) -2(-7) -35

=44+14-35

=58-35

=23 ans.

Answer 2

Given :- Find the solution of 2y(3y-5) -2(y-5) - 35 where is y = -2.

A) 21

B) 23

C) 26

D) 20

Solution :-

we have,

→ f(y) = 2y(3y - 5) -2(y - 5) - 35

putting y = (-2) , we get,

→ f(-2) = 2*(-2){3(-2) - 5) - 2{(-2) - 5)} - 35

→ f(-2) = (-4)(-6 - 5) -2(-2 - 5) - 35

→ f(-2) = (-4)(-11) -2(-7) - 35

→ f(-2) = 44 + 14 - 35

→ f(-2) = 58 - 35

→ f(-2) = 23 (Option B) (Ans.)
