Tems11 [23]

Answer:

See explanation

Step-by-step explanation:

The selling price is ​$495.

The first washing machine:

- is marked down by 30​%

$495 - 100%

$x - 100% - 30% = 70%

Find the value of x:

The second washing machine:

- is marked down by 20​% with an additional 10​% off

$495 - 100%

$y - 100% - 20% = 80%

Find y:

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

The variables y and x have a proportional relationship, and y = 5 when x = 4. What is the value of x when y = 8? Enter your answ
Charra [1.4K]

Answer

Find out the what is the value of x when y = 8 .

To prove

As given

The variables y and x have a proportional relationship.

y \propto x

y = kx

Where k is the constant of proportionality.

As y = 5 when x = 4

Put in the above

5 = 4k

k = \frac{5}{4}

Now find out the value of x , when y = 8

8 = \frac{5\times x}{4}

x = \frac{8\times 4}{5}

x= 6.5

Therefore when y = 8 than x = 6.4

Shkiper50 [21]
I don't know what the "lowest y-intercept means" so if you can reiterate and clarify I'd appreciate it, but if you understand what you're looking for then I assume that a graph would be helpful. An online useful graphing site I like is desmos. Hope I helped.
