Answer:
<em>(a) The system that models the situation: 
and 
</em>
<em>(b) David needs 40 pounds of bread flour and 240 pounds of cake flour.</em>
Step-by-step explanation:
The amount of flour mixture is 280 lb. that is 8% plain flour.
So, the amount of plain flour in the mixture will be: 
lb.
The number of pounds of bread flour and cake flour needed to make the new mixture are 
and 
respectively.
<u>So, the first equation will be</u>: 
The bread flour has 14% plain flour and the cake flour has 7% plain flour.
Thus, the amount of plain flour in bread flour 
lb. and the amount of plain flour in cake flour 
lb.
<u>So, the second equation will be</u>: 
From equation (1), we will get: 
Now substituting this into equation (2) in place of ........
Plugging this 
into equation (1), we will get.....
So, David needs 40 pounds of bread flour and 240 pounds of cake flour.
Answer:
y=4x-3
Step-by-step explanation:
Find the slope for your equation by calculating the change in y over change in x ∆y/∆x or (y2-y1)/(x2-x1)
13-5=8
4-2=2
8/2=4
We now need to use one of these coordinates to finish the equation y=4x+b
5=4(2)+b
5=8+b
b=-3
Now we rewrite our equation in slope int form as y=4x-3
You can check your work by using the other coordinate (4, 13) and see the equation balances.
