Answer:

f(x) = -2x +9

Step-by-step explanation:

We can use the slope intercept form

y= mx +b where m is the slope and b is the y intercept

y = -2x +9

Replacing y with f(x)

f(x) = -2x +9

Answer:

The answer to your question is $f(x) = -\frac{2}{9}x + 2$

Step-by-step explanation:

Data

y-intercept = 2

x-intercept = 9

Process

1.- Find the points of intersection

y-intercept = 2 (0, 2)

x-intercept = 9 (9, 0)

2.- Find the slope

m = (0 - 2)/(9 - 0)

m = -2/9

3.- Find the equation of the line

y - y1 = m(x - x1)

y - 2 = -2/9(x - 0)

Simplification

y - 2 = -2/9x

Function

f(x) = y = -2/9x + 2

In 2006, there were 12,440 starbucks stores worldwide. this is approximately 1126% more stores than 10 years earlier. How many S

Marizza181 [45]

Let's say there were "x" in 1996, therefore, "x" is the 100%.

10 years later, there are 12440, and that is 1126% "more" than "x", since "x" is 100%, 1126% more than that is 100% + 1126%, or 1226%.

so, 12440 is really 1226% of whatever "x" happened to have been back then in 1996.

now, since we know that 12440 is 1226%, what is "x" then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
12440&1226
\end{array}\implies \cfrac{x}{12440}=\cfrac{100}{1226}\implies x=\cfrac{12440\cdot 100}{1226}$

Answer:

2)$3.44

Step-by-step explanation:

4 cans and 3 loaves=11.67

8 cans and 1 loaf= 12.89.

Set up equation:

x=cans

y=loaves

$4x+3y=11.67\\8x+y=12.89$ This is the answer for question A.

Multiply eq1 by 2:

$8x+6y=23.34$

Subtract eq3 by eq2:

$5y=10.45\\y=2.09$

Substitute:

$8x+2.09=12.89\\8x=10.8\\x=1.35$

One can of soup and one loaf of bread=

$1.35+2.09 or 3.44$

So:

$$3.44$

Find the width of a rectangle 25 feet and the perimeter is 80

lukranit [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a rectangle with length 25 feet and perimeter 80 feet

To calculate - width of the rectangle

We know that ,

$\bold{Perimeter \: of \: rectangle = 2(l + b)} \\$

where b = width / breadth of rectangle

‎ ‎ ‎

substituting the values in the formula stated above ,

$\bold{80 = 2(25 + b)} \\ \\\bold{ \implies \: 25 + b = \cancel \frac{80}{2} } \\ \\ \bold{\implies \: 25 + b = 40 }\\ \\ \bold{\implies \: b = 40 - 25 }\\ \\\bold{ \implies \: b = 15 \: feet}$

hope helpful ~
