ANSWER

EXPLANATION
The given parabola has directrix x=2.
This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.
The equation of such parabola is of the form:

where (h,k)=(-5,8) is the vertex.


But the parabola opens to the left.
p=-7
The equation now becomes


The number of permutations is 5!.
5! = 5 x 4 x 3 x 2 x 1 = 120
the answer Is 170 because the amount of flour you put in you need to double the amount eggs
Answer:112 nectarines are needed.
Step-by-step explanation:
The math club is baking pies for a bake sale and they would require a number of peaches and nectarines
Let x represent the number of peaches.
Let y represent the number of peaches.
The fruit pie recipe calls for twice as many peaches as nectarines. This is expressed as
y = 2x
if it takes a total of 168 pieces of fruit for all the pies, it means that
x + y = 168 - - -- - - - - - 1
Substituting y = 2x into equation 1, it becomes
x + 2x = 168
3x = 168
x = 168/3 = 56
y = 2x
y = 2×56 = 112
Answer:
The two 50ml bottles
Step-by-step explanation:
(I will be using the $ but just change the sign to the euros)
$55/80ml= .68 per ml
45+22.5= $67.5
67.5/100 is about $.67
Therefor the two 50ml bottles is cheaper per ML and you get more product
