use the five step plan to solve the word problem. Show all five steps in youre response. doug is twice anns age. doug is 34 year

vovangra [49]

The answer is anne is 17. You would need to right the correct equation 34=2x. X is anne's age. Then you would divide both sides by 2 (really just divide 34 by 2). 34/2=17.

Need explanation 20 points The function f is such that f(x) = 2x - 6 Find f^-1(x)

Dvinal [7]

HEYA! <3

Explanation :

GIVEN :

f(x) = 2x - 6

TO FIND :

Inverse of f(x) i.e $f ^{ - 1} (x)$

SOLUTION :

FOLLOW THESE THREE STEPS :

LET Y = f(x)

$\longrightarrow \tt{y = 2x - 6}$

$\longrightarrow{ \tt{ \: 2x - 6 = y}}$

MAKE X A SINGLE TERM IN LHS SIDE

$\longrightarrow{ \tt{2x = y + 6}}$

$\longrightarrow{ \tt{x = \frac{y + 6}{2} }}$

INTERCHANGE THE VALUE OF X AND Y

$\longrightarrow{ \tt{y = \frac{x + 6}{2} }}$

Hence ,

$\boxed{ \boxed{ {f}^{ - 1} (x) = \sf{ \bold{ \frac{x + 6}{2} }}}}$

Hope I helped!

Have a wonderful day / night !

1. during first 10 seconds

Deffense [45]

Answer:

1. y=mx+b

(5 , 5) (10 , 10)

5m+b=5 10m+b=10

10m+b-5m-b=5

5m=5

m=1

5+b=5

b=0

So for 1---10s the slope is: y = x

2. y=mx+b

(10 , 10) (35 , 10)

10m+b=10 35m+b=10

35m+b-10m-b=0

25m=0

m=0

b=10

So for 10-----35s the slope is: y=10

3. y=mx+b

(35 , 10) (0 , 0)

35m+b=10 b=0

35m=10

m=2/7

So for 35----40s the slope is: y= 2/7 x
