all i know is that the double lines mean 90*
Answer:
b
Step-by-step explanation:
because the line i tercept of x is the s sloped
To make a cake :-
Quantity of flour needed = 500 g
Quantity of butter needed = 450 g
Quantity of sugar needed = 470 g
Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g
Quantity of eggs needed = 70 × 4 = 280 g
It's weight after adding all the ingredients =
=500 + 450 + 470 + 1000 + 800 + 280
= 3500 g
Mass that got lost while baking the cake :
<h3>= 12 % of 3500 </h3>





Final mass = Initial mass - mass that got lost


∴ The final mass of the cake is 3080 g .
Let f(b) = <span>3b^2+13b+4/b+4
</span>the domain of f is D = {b/ b+4#0} so b# - 4
so the undefined value of is when b = -4
Just do 7/4 and cross multiply with 1/2
