Answer:

Comparing a whole numbers and a decimals:

First let’s talk about the similarities of comparing whole numbers and decimals:

=> their place value always matters.

Now, let’s proceed to their differences

=> in comparing whole numbers, we don’t care about the value to the nearest decimal points or the value of ones. We always look at the highest value, not unless the highest values are all the same.

=> In comparing decimals, the value to the nearest decimal points or the tenths place value always matters.

Use the rational zero thereom to list all possible zeroes of the function f(x)= 5x^8-2x^5-7

Scrat [10]

Possible rational zeros are:

$\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}$

Step-by-step explanation:

We need to list all possible zeroes of the function $f(x)= 5x^8-2x^5-7$ using rational zero theorem.

The rational zero theorem.

rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e

p/q

In our given function $f(x)= 5x^8-2x^5-7$

p = 7

q = 5

Factors of p (7) = ±1, ±7

Factors of q (5) = ±1, ±5

$\frac{p}{q} =\frac{\pm1,\pm7}{\pm1,\pm5}$

So, possible rational zeros are:

$\pm1,\pm7,\pm\frac{1}{5},\pm\frac{7}{5}$

Keywords: rational zero theorem, possible zeroes

Anna [14]

Step-by-step explanation:

We need to show whether

$f^{-1}(x) = g(x)$

or

$g^{-1}(x) = f(x)$

so we'll do either one of them,

we'll convert f(x) to f^-1(x) and lets see if it looks like g(x).

$f(x) = e^x - 1$

we can also write it as:

$y = e^x - 1$

now all we have to do is to make x the subject of the equation.

$y+1 = e^x$

$\ln{(y+1)} = x$

$x=\ln{(y+1)}$

now we'll interchange the variables

$y=\ln{(x+1)}$

this is the inverse of f(x)

$f^{-1}(x)=\ln{(x+1)}$

and it does equal to g(x)

$g(x)=\ln{(x+1)}$

Hence, both functions are inverse of each other!

This can be shown graphically too:

we can see that both functions are reflections of each other about the line y=x.

A line passes through the point (-8,7) and has a

zaharov [31]

Answer:

y = (-5/2)x + 27

Step-by-step explanation:

Use the point slope formula y = mx + b.

Replace m with -5/2, x with -8 and y with 7:

7 = (-5/2)(8) + b. Find the y-intercept, b:

7 = -20 = b, or b = 27

The equation of this line is y = (-5/2)x + 27.
