Answer:
3x - y +5=0
Step-by-step explanation:
<u>Slope:</u><u>-</u><u> </u>
=> m = 2-8/-1-1 = -6/-2
=> m = 3
<u>Using</u><u> point</u><u> slope</u><u> form</u><u> </u><u>:</u><u>-</u><u> </u>
=> y - 2 = 3 ( x - (-1))
=> y - 2 = 3x + 3
=> 3x - y +5 = 0

Answer:
Density = 1.042 grams /cm^3
Step-by-step explanation:
Work out the mass of each of three in a unit volume (cm^3)
Givens
- Apple Juice = 1.04 grams / cm^3
- Fruit Syrup = 1.6 grams / cm^3
- Sparkling water = 0.99 grams / cm^3
Mixture
35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams
25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 = 40 grams
270 cm^3 water = 0.99 * 270 267.3 grams
Total Mixture
- Volume = 25 + 35 + 270 = 330 cm^3
- Mass = 36.4 + 40 + 267.3 = 343.7 grams
Density
Density = mass / volume = 343.7 / 330 = 1.0415
Answer
1.042 grams / cm^3
