Ok so you’ve got to remember Y=mx+b
So the first one would would go to y=5x-2 the reason why it isn’t plus to is because it’s a negative.

M= -2 B=5 goes to Y=-2x+5
M=3 B=4 goes to Y=3x+4

If a hen and a half lay an egg and a half in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?

Good Luck!! First correct answer MIGHT get brainliest!!

Answers

Answer:

72 eggs

Step-by-step explanation:

Let’s simplify the answer: if one and a half hens lay an egg in 18 hours, how many eggs will 6 hens lay in 6 days? So 18/3=6, and 6x2=12. One hen can lay an egg in 12 hours. Which means a hen can lay 2 eggs in one day. 2x6=12. So 6 hens can lay 12 eggs in one day. 12x6=72. In 6 days, 6 hens can lay 72 eggs

Oh I answered first btw if you’re wondering later

Answer:

4 eggs

Step-by-step explanation:

One and half hen=1 egg in two days

=3 hens(one and half +one and half)=two eggs in four days

6 hens(half a dozen is equal to 12 divided by 2=6)=? Eggs in six days

=the 6 hens divided by 3 hens =2

The two eggs gotten from the 3 hens + the other 2=4 eggs in six days

Inequalities

Answers

The answer to this question is the one on the left then the right then the one sign is the correct answer
Answer: 35x+20≥1,000; x ≤28


Explanation:

There is already 20 bags and 35 bags are filled per hour. So 35 is the rate of change and 20 is the constant

35x+20 ≥1,000
-20 -20

35x ≥980
Divide both sides by 35 to isolate x
=28

Flip the sign because you divided

x≤28
