Answer:
100(x) /÷0p1
Step-by-step explanation:
t(x) factor 4
The rate of change is 1/2
Because it’s the constant and whatever x is, it would always multiply by 1/2
Answer:
E) $1.05
Step-by-step explanation:
before sale: $1.35×12=$16.20
during sale: $0.95×(12×3)=$34.20
total money spent=$16.20+$34.20=$50.40
total bars bought=12+(12×3)=48

Equation of a parabola is written in the form of f(x)=ax²+bx+c.
The equation passes through points (4,0), (1.2,0) and (0,12), therefore;
replacing the points in the equation y = ax² +bx+c
we get 0 = a(4)²+b(4) +c for (4,0)
0 = a (1.2)²+ b(1.2) +c for (1.2,0)
12 = a(0)² +b(0) +c for (0,12)
simplifying the equations we get
16a + 4b + c = 0
1.44a +1.2b + c = 0
+c = 12
thus the first two equations will be
16a + 4b = -12
1.44 a + 1.2b = -12 solving simultaneously
the value of a = 5/2 and b =-13
Thus, the equation of the parabola will be given by;
y= 5/2x² - 13x + 12 or y = 2.5x² - 13x + 12
