The value of varies directly with . If = 4, then = 12. What is the value of when = 6?

1 answer:

4 0

Write the correct equation. Direct variation problems are solved using the equation y = kx. When dealing with word problems, you should consider using variables other than x and y, you should use variables that are relevant to the problem being solved. Also read the problem carefully to determine if there are any other changes in the direct variation equation, such as squares, cubes, or square roots.

HELP<br> Write an equation of a line passing through (-8, 6) and parallel to the line y=-4x - 1

MArishka [77]

The line is parallel so it has the same slope as the other line, -4.

Substitute the x and y variables with the given points and find the y-intercept.

(-8, 6)

y = -4x + b

6 = -4(8) + b

6 = -32 + b

6 + 32 = b

38 = b

So the equation is:

y = -4 + 38

A pet store has three fish tanks, each holding a different volume of water and a different number of fish. Tank AAA holds 40\tex

bearhunter [10]

Answer:

C, A and B

Step-by-step explanation:

Tank A holds 40 Liters and 5 fish.

Volume per fish of Tank A $=40 \div 5 =$ 8 fish per liter$

Tank B holds 100 Liters and 12 fish.

Volume per fish of Tank B $=100 \div 12 =$ 8.33 fish per liter$

Tank C holds 180 Liters and 23 fish.

Volume per fish of Tank C $=180 \div 23 =$ 7.83 fish per liter$

Therefore, the volume per fish from least to greatest is:

7.83, 8 and 8.33

These correspond to the tanks: C, A and B respectively.
