To represent the length of the string, we can use the variable y.

$y=4x$

Y is four times longer than X.

Hope this helps!

Here the given expression is

$y =(\frac{3}{4})^x$

We need to find the value of y when x =3 . So we substitute the value of x in the given expression.

$y =(\frac{3}{4})^3 = \frac{27}{64} =0.4$

So when x=3, y=0.4 and that's the required answer.

Answer:

Step-by-step explanation:

by replacing x and y with their given values ,

we get :-

=》2x + 7y - 10

=》(2 × 4) + (7 × 3) - 10

Please help me with this problem<br><br>

Answer:

g(x) = -5x

Step-by-step explanation:

If the point from f(x) is plotted using the slope, the coordinate would be located at (1, 5) since the slope of 5x tells us we go up 5 units from the origin and over 1 unit to the right. That point will be reflected through the x-axis to land at (1, -5). That means that the equation of the new line would be

g(x) = -5x
