Answer:
f(3) = -20
Step-by-step explanation:
To find the value of a function, substitute the number for the variable and do the arithmetic.
f(x) = -2x^2 +x -5 . . . . . . given
f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3
f(3) = -2(9) +3 -5 = -18 +3 -5
f(3) = -20
Answer:
20 days
Step-by-step explanation:
The correct answer would be 6
y = 3p+85, because they are vertical angles.
x = 2p ‐ 10, because they are vertical angles too.
