$1 \% = \frac{1}{100}\\ \\90 \% * x =6.4 \\ \\\frac{90}{100}x=6.4 \\ \\\frac{9 }{10 }x=6.4 \ \ *(\frac{10}{9})\\ \\x= 6.4 *\frac{10}{9}\\ \\x=\frac{64}{9}\\ \\x = 7\frac{1}{9}$

Write an equation in slope-intercept form for the line containing the giving points (10,2) (2,-2)

zysi [14]

(y - yo) = m.(x - xo)

(-2 - 2) = m.(2 - 10)

-4 = m.(-8)

m = -4/-8

m = 1/2

(y - yo) = 1/2.(x - xo)

(y - 2) = 1/2.(x - 10)

y - 2 = 1/2x - 5

y = 1/2x - 5 + 2

y = 1/2x - 3

elena-s [515]

I think it would be 54 words per minute

36÷2=18 which is 1/3 of a minute so we multiply 18 by 3 to get how many words in one minute, 18×3=54

inverse of f(x)=(x+1)/(2x+1) I know how to get the inverse if the bottom or top of the fraction have an x on their own, but i am

kodGreya [7K]

To solve for the inverse
1. replace f(x) with y
2. switch all x with y and y with x
3. solve for y
4. replace y with $f^{-1}(x)$

$f(x)=\frac{x+1}{2x+1}$
replace
$y=\frac{x+1}{2x+1}$
switch
$x=\frac{y+1}{2y+1}$
solve
$(2y+1)(x)=y+1$
$2yx+x=y+1 [tex]x-1=y-2xy$
$x-1=y(1-2x)$
$\frac{x-1}{1-2x}=y$
$y=\frac{x-1}{1-2x}$
replace
$f^{-1}(x)=\frac{x-1}{1-2x}$
