(d): y = mx+n

m = -2/3 ⇒ y = (-2/3)x +n

A(-4, 6) ∈ d ⇒ 6 = (-2/3)·(-4) +n ⇒ 6 = 8/3 +n ⇒

⇒ n = 6 - 8/3 ⇒ n = 10/3

Now, we have:

y = (-2/3)x +10/3

Which numbers are solutions to the inequality x < −2, using the replacement set {−5, −2.6, −2, −1.5, −0.8, 1}?

UkoKoshka [18]

X < -2

Just find the numbers that are less than -2.

-5, -2.6, -2, -1.5, -0.8, 1

With negative numbers, the numbers that seem 'bigger' than them are actually smaller.

So '-5' and '-2.6' are the only one's that are less than -2.

Sati [7]

Answer:

The profit of the bakery for this batch of rolls is C. $ 132

Step-by-step explanation:

You know the following this about the problem:

xy=300 is the total cost of the production of the rolls, where x is the cost of the rolls and y is the number of rolls.
Day 1 the bakery sold 4/5 of the rolls at 1.50 its value.
Day 2 the bakery sold 1/5 of the rolls ar 0.8 of the price of Day 1.

$Day1=1.50x\frac{4}{5}y=\frac{3}{2}x\frac{4}{5}y=\frac{6}{5}xy\\Day2=0.8\frac{3}{2}x\frac{1}{5}y=\frac{4}{5}\frac{3}{2}x\frac{1}{5}y=\frac{6}{25}xy$
