8. Suppose y varies directly as x. If y = -4 when x = 32, find x when ys -0.

Nata [24]

Answer:

$x=0$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

in this problem

For x=32, y=-4

Find the value of the constant of proportionality k

$k=y/x$

substitute

$k=-\frac{4}{32}$

simplify

$k=-\frac{1}{8}$

The linear equation is

$y=-\frac{1}{8}x$

Find x when the value of y=0

Remember that

In a proportional relationship the line passes through the origin

If y=0

then

the value of x must be equal to zero

therefore

$x=0$

55 percent of 120 books are fictional how many are non fictional

adelina 88 [10]

55 percent of 120 is 66.

120 - 54 = 66.

66 Books are fictional

So that being said, the other part of your remaining total is 54. 54 books are non-fictional. (The above where I said 120-54). Since 120 - 66 = 54.

Water flows from a container at a rate of 2.5 litres per minute . The water flows into a tank that already holds 50 litres. How

harkovskaia [24]

Y = 2.5x + 50.....with y being the total liters in the tank and x being the number of seconds

when total liters is 765....so sub in 765 for y and solve for x
765 = 2.5x + 50
765 - 50 = 2.5x
715 = 2.5x
715 / 2.5 = x
286 = x <==== so it would take 286 seconds
