Answer:
A
Step-by-step explanation:
A parcent as a fraction would be /100. So the answer would not be C or D. And since it isn't B, the answer is only A
We can use point slope form to solve for this.
y - 1 = -2(x - 2)
Simplify.
y - 1 = -2x + 4
Add 1 to both sides.
y = -2x + 5
Now, we can input -3 for x and solve for y, or r in this case.
y = -2(-3) + 5
y = 6 + 5
y = 11
r = 11
It would take her 10.5 hours to drink the whole jug.
Step-by-step explanation:
Given,
Cups of water in jug = 7
Water drunk every hour =
of cup
Let,
x be the number of hours.
According to given statement;

Multiplying both sides by 

It would take her 10.5 hours to drink the whole jug.

Answer:
x = -13 or 2
Step-by-step explanation:
x² + 11x + ¹²¹/₄ = ¹²⁵/₄
(x + ¹¹/₂)² = ¹²⁵/₄
x + ¹¹/₂ = ±¹⁵/₂
x = -¹¹/₂ ± ¹⁵/₂
x = -13 or 2
