Find the x and y intercepts Y-2xy+4x=1

Mathematics
1 answer:
liubo4ka [24]2 years ago
7 0

Answer:

x = \frac{1}{4}

y= 1

Step-by-step explanation:

Given

y - 2xy + 4x = 1

Solving (a) The x intercept

Let y = 0

y - 2xy + 4x = 1

0 - 2x*0 + 4x = 1

0 - 0 + 4 x = 1

4x = 1

Divide both sides by 4

x = \frac{1}{4}

Let x = 0

y - 2xy + 4x = 1

y - 2y * 0 + 4*0 = 1

y - 0 + 0 = 1\\

y= 1

How many gallons of pure water should be evaporated from 160 gallons of a solution containing 12% salt
AfilCa [17]

Answer:

66 gallons

Step-by-step explanation:

Given that initially 160 gallons of a solution containing 12% salt.

So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.

Let x gallons of water get evaporated so that the remaining solution contains 20% salt.

The remaining amount of solution = 160-x gallons.

As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so

19.2 = 20% of (160-x)

\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\

\Rightarrow x= 66 gallons

Hence, 66 gallons of water must be evaporated to get a 20% salt solution.

Christopher is going to install wallpaper on the four walls of his room. Two of the walls are 14 feet long by 9 feet high. The o
Aliun [14]
Given:
2 walls - 14ft by 9ft
2 walls - 20ft by 9ft

Wall 1 & 2 = 14ft * 9ft = 126 ft² x 2 = 252 ft²
Wall 3 & 4 = 20ft * 9ft = 180 ft² x 2 = 360 ft²

Total area = 252 ft² + 360 ft² = 612 ft²

Cost of 1 single roll: $20
612 ft² ÷ 18 ft² = 34 rolls * $20 = $680

Cost of double roll: $40
612 ft² ÷ 54 ft² = 11.33 rolls ⇒ 12 double rolls
12 * $40 = $480

If Christopher opts for 1 single roll of wallpaper, he'll spend $680.
If he opts for double roll of wallpaper, he'll spend $480.

Double roll of wallpaper is the cheaper option. He'll save $200 if he'll buy the double roll of wallpaper.
