Consider this function. f(x) = -3x +3 Which graph represents the inverse of function f?

lesya692 [45]

The inverse of the given function is y = 3-x/3. The graph is attached below.

<h3>Inverse of a function</h3>

Functions are written in terms of variables. Given the linear function

f(x) = -3x + 3

Find the inverse

y = -3x + 3

Replace the variables

x = -3y + 3

Make y the subject of formula

3y = -x + 3

y = 3-x/3

Plot the graph of the resulting function

on the bad side

For a score with a range between 300-850, a credit score of 700 or above is generally considered good. A score of 800 or above on the same range is considered to be excellent. Most credit scores fall between 600 and 750. Hope that this helps you and have a great day :)

Fertilizer is sold in 100 pound bags labelled with the amount of nitrogen ( N), phosphoric acid ( P2O5), and potash ( K2O) prese

arlik [135]

Answer:

4 pounds of of Vigoro Ultra Turf fertilizer and 1 pound of Parkera's Premium Starter will yield the required mixture.

Step-by-step explanation:

In bag of Vigoro Ultra Turf fertilizer:

29 pounds of nitrogen, 3 pounds of phosphoric acid, and 4 pounds of potash

In bag of Parkera's Premium Starter:

18 pounds of nitrogen, 25 pounds of phosphoric acid, and 6 pounds of potash

Let the mass of Vigoro Ultra Turf fertilizer = x

Amount of nitrogen in x amount = 29 x

Amount of phosphoric acid in x amount = 3x

Let the mass of Parkera's Premium Starter= y

Amount of nitrogen in y amount = 18 y

Amount of phosphoric acid in y amount = 25 y

Amount of nitrogen in desired mixture formed by combing x and y fertilizers bag : 134 pounds

29 x + 18 y = 134 ..[1]

Amount of phosphoric acid in desired mixture formed by combing x and y fertilizers bag : 37 pounds

3x + 25 y = 37 ..[2]

Solving [1] anf [2] by substitution method :

$x=\frac{134-18y}{29}$

$3\times \frac{134-18y}{29}+25y=37$

y = 1

$x=\frac{134-18y}{29}=4$

4 pounds of of Vigoro Ultra Turf fertilizer and 1 pound of Parkera's Premium Starter will yield the required mixture.

Find the value of 8/15×2/13 Although these numbers aren't quite as nice as the ones from the example, the procedure is the same,

xz_007 [3.2K]

Answer:

$\frac{16}{195}$

Step-by-step explanation:

To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that

$\frac{a}{b}*\frac{c}{d}=\frac{a*c}{b*d}$

Substituting a,b,c and d for 8,15,2 and 13 we obtain that

$\frac{8}{15}* \frac{2}{13} =\frac{16}{195}$
