Answer:
Step-by-step explanation:
Piecewise function 'f' has been given as,
f(x) = 4x + 3 when x < 0
(x + 7) when x ≥ 0
By using the piecewise function,
a). f(-2) = 4(-2) + 3 (Use f(x) = 4x + 3, since x = -2 is less than 0)
= -8 + 3
= -5
b). f(0) = 0 + 7 (Use f(x) = x + 7, since x = 0 is equal to 0)
= 7
c). f(1) = 1 + 7 (Use f(x) = x + 7, since x = 1 is greater than 1)
= 8
Answer:
3. -2
4. 12
5. -4
Step-by-step explanation:
For all problems, let n represent "a number." You will note that when we specify an operation to be done on the equation, it is done to <em>both sides of the equation</em>.
__
3. 5n +(-3) = -13
5n = -10 . . . . . . add 3
n = -2 . . . . . . . . divide by 5
The number is -2.
__
4. (n/2) -7 = -1
n/2 = 6 . . . . . . . add 7
n = 12 . . . . . . . . multiply by 2
The number is 12.
__
5. 2n -1 = -9
2n = -8 . . . . . add 1
n = -4 . . . . . . divide by 2
The number is -4.
It is 380. because it goes up by 30 each month so multiply 13x30=380.
Hope that helps!!
