Step-by-step explanation:
Solution,
f(x) = -4x2 + 19
f(x)=-8+19
f(x)=27
As it is a constant function, therefore
f(-7)=27
Answer:
1.5 bananas.
Step-by-step explanation:
1.5 x 2 = 3
eg. x is the number of milk chocolate candy bars, y is the number of white chocolate of candy bar
x + y = 330
2x + 3y = 900
From first equation
x + y = 330
x = 330 - y
From second equation, subtitute x with 330 - y
2x + 3y = 900
2(330-y) + 3y = 900
660 - 2y + 3y = 900
660 + y = 900
y = 900-660
y = 240
The number of white chocolate candy bars is 240
