what is the common number to be subtracted from each term of the ratio 11:8 to get the new ratio 2:1.?

JulijaS [17]

Answer:

5 should be subtracted from each term

Step-by-step explanation:

$\frac{11-x}{8-x}=\frac{2}{1}$

Cross multiply,

1 * (11 - x) = 2*(8-x)

11 -x = 2*8 - 2*x

11 - x = 16 - 2x

Subtract 11 from both sides,

-x = 16 - 2x - 11

-x = 5 - 2x

Add 2x to both sides

-x +2x = 5 - 2 + 2x

x = 5

Which function grows the fastest for large values of x? f(x)=8x f(x)=3x f(x)=4x2+3 f(x)=1.5x 20 points

Aleonysh [2.5K]

The 4 functions are:
$f_1 (x) = 8x$
$f_2(x)=3x$
$f_3(x)=4x^2+3$
$f_4(x)=1.5 x$

Let's keep in mind that for large values of x, a quadratic function grows faster than a linear function:
$ax^2 \ \textgreater \ kx$ for large values of x

In this problem, we can see that the only quadratic function is $f_3(x)$ , while all the others are linear functions, so the function that grows faster for large values of x is
$f_3(x) = 4x^2 +3$
