Answer: I’m not sure but I think the answer is $255
Step-by-step explanation:
Answer: x(1-0.33) or 0.67 x
Step-by-step explanation:
The old soup recipe contained sodium per serving = x mg
According to the question,
The new soup recipe contains 33% less sodium per serving than the old soup recipe.
That is, the Sodium per serving in the new soup = the Sodium per serving in the new soup - 33% of the Sodium per serving in the new soup
= x - 33% of x
= x - 0.33 x ( since 1% = 0.01 ⇒ 33 % = 0.33 )
= x(1-0.33)
= x(0.67)
Vertex form is
y = a(x - b)^2 + c
here a = -3 and b = -18 so we have
y = a(x + 3)^2 - 18
when x = 0 , y= 0 ( the y-intercept) so:-
0 = a(3^)2 - 18
9a = 18
a = 2
so the parabola is y = 2(x + 3)^2 - 18
x intercepts found as follows:-
2(x + 3)^2 - 18 = 0
(x + 3)^2 = 9
x + 3 = +/- sqrt9 = +/- 3
so x intercepts are 0 and -6 Answer
