Only D is correct, it intersects at 90 degrees so it cant be obtuse or acute and never intersecting would be parallel lines <span />
One form of the relation of inverse variation is y = k/x.
first step: Find the value of k: Taking the values x=5 and y = 4, 4=k/5, or k=20. Then, y = 20/x.
Next: Let y = 7 and find the corresp. value of x: 7=20/x, or 7x=20, or
x = 20/7 (answer)
Answer:
to get x by itself so divide 5 by 2 and then add 7 to the other side
Step-by-step explanation:
2x-7=5
x-7=2.5
x=2.5+7
x=9.5

+ </span><span>300g of 20% sugar solution: 300*20%= 60 g
The total of sugar: 20+60= 80g
And The </span><span>concentration is 80:(200+300)= 80:500= 16%
