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

Answer:
y=-x-2
Step-by-step explanation:
y+5=-(x-3)
y+5=-x+3
y=-x+3-5
y=-x-2
Answer:
Step-by-step explanation:
<u>Take any two points or coordinated from the graph.</u>
Let's take (2,2) and (0,-3)
So,
Hence,
![\sf Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\Slope = \frac{-3-2}{0-2} \\\\Slope = \frac{-5}{-2} \\\\Slope = \frac{5}{2} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20Slope%20%3D%20%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%20%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-3-2%7D%7B0-2%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-5%7D%7B-2%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B5%7D%7B2%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
