$y_{-2}=5\cdot(-2)-8=-10-8=-18$ $y=5x-8$ $12=5x-8$ $12+8=5x$ $20=5x$ $x=\frac{20}{5}$ $x=4$

A water container is 1/8 full. 35 litres if water are now poured into the container. The container is now 1/4 full.

Aloiza [94]

Answer:

The container can hold 280 liters of water.

Step-by-step explanation:

Proportions

The water originally fills 1/8 of a container. Then 35 lt of water are poured into the container and now it's 1/4 full.

If we subtract the final portion of the tank minus the original portion of the container, we obtain the portion that was poured into.

$\mathrm{Portion\ poured }=\frac{1}{4}-\frac{1}{8}=\frac{2}{8}-\frac{1}{8}=\frac{1}{8}$

If 35 liters of water is 1/8 of the tank, then it can hold 35*8 = 280 liters.

The container can hold 280 liters of water.

.The endpoints of AB are A(1,4) and B(6,-1).

Brums [2.3K]

Answer:

5√2

Step-by-step explanation:

Finding distance :-

d = √{ ( 1 -6)² + (4+1)²}
d = √{ -5² + 5² }
d = √{ 25 + 25}
d = √50
d = 5√2

What is the equation of the line that passes through (6,4) and (4,1)

Murrr4er [49]

Answer:

y = 3/2*x - 5

Step-by-step explanation:

Lets say that P1=(6,4) and P2=(4,1) and that the form of the equation must be y=m*x+b where m is the slope and b the independent variable. Then having two given points we can use the slope formula to find the slope value as:

P1=(x1,y1) and P2=(x2,y2)

slope formula ---> m=(y2-y1)/(x2-x1)

Replacing the given points ---> m=(1-4)/(4-6) = 3/2

then replacing the slope value obtained:

y = 3/2*x + b

Now lets find the value of b. For this we have to replace in the equation a point it can be P1 or P2, i will replace P2:

1 = 3/2*4 + b

1 = 6 + b

1 - 6 = b

-5 = b

therefore the line equation is:

y = 3/2*x - 5

On the checkerboard, 4/10 of the pieces left are red. What fraction of the pieces left are black? Write the equation.

Alexeev081 [22]

Answer:

The fraction of black pieces left is $\frac{6}{10}$

Step-by-step explanation:

Given as :

On the checkerboard , The fraction of red pieces left = $\frac{4}{10}$

Let The fraction of black pieces left = x

So, The fraction of black pieces left = x = 1 - $\frac{4}{10}$

Or, x = $\frac{10-4}{10}$

Or, x = $\frac{6}{10}$

Hence The fraction of black pieces left is $\frac{6}{10}$ Answer
