Answer:

option D

Step-by-step explanation:

Domain is the set of x values for which the function is defined

To find domain restriction first we simplify the given expression

Factor both numerator and denominator

\frac{y^2-3y-40}{y^2+9y+20}

y^2-3y-40=(y-8)(y+5)

y^2+9y+20=(y+4)(y+5)

Replace the factors in our expression

\frac{(y-8)(y+5)}{(y+4)(y+5)}

Both top and bottom have y+5, so we cancel it out

\frac{(y-8)}{(y+4)}

To find restriction for y , set the denominator =0 and solve for y

y+4=0

so y=-4

y=-4 makes the denominator 0

So, y not equal to -4

When Anders make scones he uses sugar, butter and flour in the ration 2:3:6. Hehas 200g of sugar, 300g of butter and 450g of flo
katovenus [111]

The amounts of sugar, butter, and flour used are 150 grams, 225 grams, and 450 grams, respectively.

Anders makes scones with three ingredients : sugar, butter, and flour. The ratio of the amounts of sugar, butter, and flour is 2:3:6. The available amounts of the ingredients in the kitchen include 200 grams of sugar, 300 grams of butter, and 450 grams of flour. He makes as many scones as he can with these ingredients.

Let the amounts of sugar, butter, and flour be 2x, 3x, and 6x, respectively. The maximum proportion is for flour. The amount of flour used is 450 grams. The amount of butter used is half of that of the flour. The amount of sugar is one-third of that of flour.

B = (3x/6x)*450 = 225

S = (2x/6x)*450 = 150
