Answer:

Ali's heart rate is 135 times per minute.

Step-by-step explanation:

Let Ali's heart rate be denoted by <em>x</em> times per minute.

It is provided that Ben's heart beats 18 times per minute more than Ali.

The ratio of their heart rates was 15:17.

That is:

$\frac{15}{17}=\frac{x}{x+18}$

Solve for <em>x</em> as follows:

$\frac{15}{17}=\frac{x}{x+18}$

$15(x+18)=17x\\15x+270=17x\\2x=270\\x=135$

Thus, Ali's heart rate is 135 times per minute.

If f(x) = 1-x2 and g(x) = 1 - x which is the rule of function (f – g)(x)?

V125BC [204]

Answer:

-x^2 +x

Step-by-step explanation:

f(x) = 1-x^2

g(x) = 1 - x

f(x) - g(x) = 1-x^2 - (1 - x )

Distribute the minus sign

= 1-x^2 -1 +x

Combine like terms

= -x^2 +x
