Answer:
The given point A (6,13) lies on the equation. True
The given point B(21,33) lies on the equation. True
The given point C (99, 137) lies on the equation. True
Step-by-step explanation:
Here, the given equation is : 
Now,check the given equation for the given points.
1) A (6,13)
Substitute x = 6 in the given equation

⇒ y= 13
Hence, the given point A (6,13) lies on the equation.
2) B (21,33)
Substitute x = 21 in the given equation

⇒ y = 33
Hence, the given point B(21,33) lies on the equation.
3) C (99, 137)
Substitute x = 99 in the given equation

⇒ y = 137
Hence, the given point C (99, 137) lies on the equation.
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
9 x 6 = 54 is this right I'll do distributive property next time
Answer:
160 mL of fruit juice and 400 mL of sparkling water
Step-by-step explanation:
According to the statement we have that the ratio between fruit juice and sparkling water is 2/5.
Therefore, we could also say that:
200/500
with it could be done with 200 mL of fruit juice and 500 mL of sparkling water, so for 400 mL, how much would it be:
400 * 200/500 = 160
Therefore, the largest amount of the drink can be made with 160 mL of fruit juice and 400 mL of sparkling water.
