Answer:
y = 2x - 3
Step-by-step explanation:
Let (2, 1) =
Let (4, 5) =
Slope formula:
Equation of a line, point-slope formula:
Just like the previous one
if the ship travelled a total of 149 miles, then let's say it travelled East "d" miles and thus it travelled North the slack of 149 and "d", thus " 149 - d".
now, if the rate travelling East is say "r", then the faster rate going North is " r + 3".
solve for "r".
Answer:
The answer to your question is below
Step-by-step explanation:
a)
32.6 grams of H₂O to moles
molar mass of water = 2 + 16 = 18 g
18 g ------------------- 1 mol
32.6 g ---------------- x
x = (32.6 x 1)/18
x = 1.81 moles of H₂O
b) 22.7 grams to molecules
18 g of H₂O ----------------- 6.023 x 10²³ molecules
22.7 g of H₂O ------------- x
x = (22.7 x 6.023 x 10²³)/18
x = 7.59 x 10²³ molecules
Length = x - 2
Width = x - 5
Explanation:
Area = x^2 - 7x + 10
Area = (x - 2)(x - 5)
Area = Length x Width
Length = x - 2
Width = x - 5
