What happens to the value of the expression c+2 as c increases..please help

boyakko [2]

c+2 increases linearly with c. That means that if c increases by 1, c+2 will increase by 1; if by 2, c+2 will increase by 2; and so on.

y = c+2 is a "linear function of c."

Find the inverse of f(x)=2x+1

satela [25.4K]

Answer:

$h(x) = \frac{x-1}{2}$

Step-by-step explanation:

The inverse function is the function which when plugged in to the original one yields the argument (x).

Knowing this we do the following, let h(x) be the inverse function of f:

$f(x)=2x+1 \ \ \ \ f(h(x)) = 2(h(x)) + 1 = x\\h(x) = \frac{x-1}{2}\\Now \ we \ verify \ if \ it \ yields \ x.\\f(h(x)) = f(\frac{x-1}{2}) = 2(\frac{x-1}{2}) + 1 = x -1 + 1 = x\\Thus \ h(x) \ is \ the \ inverse\ function \ of \ f$

Help with this math question

Ulleksa [173]

Answer:

$-\frac{13\sqrt{x} }{x}$

Step-by-step explanation:

We have been given the following expression;

-13/√x

In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

$-\frac{13}{\sqrt{x}}=-\frac{13\sqrt{x} }{\sqrt{x}\sqrt{x}}\\ \\-\frac{13\sqrt{x} }{\sqrt{x^{2} } }\\\\-\frac{13\sqrt{x} }{x}$

X:y = 9:7 Form an equation that links x and y

sleet_krkn [62]

Equations are expressions with equal values

The equation that links x and y is $7x = 9y$

<h3>How to determine the equation</h3>

The ratio is given as:

$x : y = 9 : 7$

Express the ratio, as a fraction

$\frac xy = \frac 97$

Cross multiply

$7 *x = 9 * y$

Evaluate the product

$7x = 9y$

Hence, the equation that links x and y is $7x = 9y$
