A store sells bread and milk. On Tuesday, 3 loaves of bread and 2 litres of milk were sold for €6.25. On Thursday
poizon [28]

Answer:

A store sells bread and milk. On Tuesday, 3 loaves of bread and 2 litres of milk were sold for €6.25. On Thursday  4 loaves of bread and 5 litres of milk were sold for €10.90. If b = the price of a loaf of bread and m = the price of

one litre of milk, Tuesday's sales can be written as 3b+2m=6.25.

Part A Using simplest terms, write an equation in band m for Thursday's sales.  

PartB calculate the values of b and m

3b + 2m= 6.25  >> Tuesday equation 1

4b +  5m = 10.90 >> Thursday equation 2

Subtract equation 1 and 2

3b+2m-6.25-4b+5m-10.90= 0

b+7m-4.65= 0

b+7m= 4.65+0

b+7m= 4.65

b= 4.65 - 7m

if b= 4.65-7m

then substitute b in b+7m=4.65

4.65-7m+7m= 4.65

4.65-m= 4.65

4.65-4.65= m

m= 0

Please help and explain.
Radda [10]

Explanation:

Vertex form of a quadratic function is given by y = a(x - h)² + k

where

1) 'a' determines if parabola is stretched or compressed.

   If a > 1 then graph is stretched by a factor of a.

   If 0 < a < 1, then graph is compressed by a factor of a.

2) If a > 0 then graph opens upwards with a happy face. (minimum)

3) If a < 0 then graph opens downwards with a sad face. (maximum)

4) (h, k) is the vertex point

5) The axis of symmetry is x = h

While solving for y = 1(x - 4)² + 3

Identify following's:

Vertex: (h, k) = (4, 3)

Axis of symmetry: x = 4

Max/Min: As here a > 0, Minimum (4, 3)

Stretch/compression: a = 1, the graph is stretched by a factor of 1.

Direction of opening: As a > 0, the graph opens upwards.
