Answer:
Step-by-step explanation:
(3,4) ; (6,-1)
slope = y₂ - y₁ / x₂-x₁
= -1 - 4 / 6-3
= -5/3
(2x)sqrt 2- 64y2 is the answer
X = y + 12. You then substitute or plug in that from the first equation into the second equation. You get (y+12)+y=18, then you simplify to get your y value. In this case y = 3. The you can plug your y value into either equation. (x+3=18) or (x-3=12) or (x=3+12) either way you get x=15 and y=3.
4(x+1) is the only one equal to 0
You just multiply 0.3 and 8 to get 2.4. So, peter's dog will eat 2.4 kilograms of dog food in 8 days
