Y is directly proportional ( x+2)² <br> when x = 8 y= 250 <br> find y when x = 4

sladkih [1.3K]

Answer:

y=90 when x=4

Step-by-step explanation:

We are given that

$y\propto (x+2)^2$

When x=8 and y=250

We have to find the value of y when x=4

$y=k(x+2)^2$

Where k= Proportionality constant

Substitute the values

$250=k(8+2)^2$

$250=100k$

$k=\frac{250}{100}$

$k=5/2$

Now, substitute x=4 and k=5/2

Then, we get

$y=\frac{5}{2}(4+2)^2$

$y=\frac{5}{2}\times 36$

$y=90$

The time Louis spends commuting to the gym can be represented by two expressions:

kakasveta [241]

Answer:

The expression that represents the total time Louis spends commuting to and from the gym each day is 8(x-2y)

Step-by-step explanation:

Given that the time Louis spends commuting to the gym can be represented by two expressions:

Time to gym: $2x-6y\hfill (1)$

Time from gym: $6x-10y\hfill (2)$

To find the expression that represents the total time Louis spends commuting to and from the gym each day :

The total time Louis spends commuting to and from the gym each day is equal to the sum of the Time to gym and Time from gym

Total time Louis spends commuting to and from the gym each day=2x-6y+6x-10y

=8x-16y

=8(x-2y)

Therefore Total time Louis spends commuting to and from the gym each day is 8(x-2y)

The expression that represents the total time Louis spends commuting to and from the gym each day is 8(x-2y)
