The desired value will be the solution to the equation ...
... (5 - a) = 20 + (6a - 1)
... 5 - a = 19 + 6a . . . collect terms
... 5 = 19 + 7a . . . . . . add a
... -14 = 7a . . . . . . . . . subtract 19
... -2 = a . . . . . . . . . . . divide by the coefficient of x
The value of the variable is -2.
Answer:
19
Step-by-step explanation:
f(x) = 2x^2 +1
Let x =3
f(3) = 2 (3)^2 +1
= 2 *9 +1
= 18 +1
= 19
Answer: -40
Multiply 2 by 4.
8+4•3-30•2
Multiply 4 by 3
8+12-30•2
Multiply-30 by 2
8+12-60
Simplify by adding and subtracting:
Add 8 and 12
20-60
Subtract 60 from 20
-40
