( x-5)/-2=(x-1)/-3
Cross multiply
-3(x-5)=-2(x-1)
Distribute
-3x +15 = -2x +2
Add 2x to both sides
-x +15 = 2
Subtract 15 from both sides
-x = -13
x=13

If the question is (x-5)/-2 = (x-1)/3 then the answer would be as shown below

first cross multiply to get
-2(x-1) = 3(x-5)

then distribute
-2x+1 = 3x-15

move over the -2x by adding 2x to both sides and move -15 by adding 15 to both sides... this gives you 16 = 5x

divide both sides by 5 to get x = 16/5

*** if the problem is x-(5/-2) = x-(1/-3) then see below for the answer and explanation 

this is not a possible question as anything you plug in for x will simplify to an unequal equation, plug in zero and get -(5/-2)=-(1/-3) this is not true so can not be possible

ad-work [718]

Answer:

C = 50.24

A = 7,925.540864 (Round to whatever you want)

Step-by-step explanation:

c = 2πr

c = 2(3.14)(8)

c= 50.24

A = πr^2

A = (3.14)(50.24)^2

A = 7,925.540864

For all values of x
Yuliya22 [10]

Answer:

A.) gf(x) = 3x^2 + 12x + 9

B.) g'(x) = 2

Step-by-step explanation:

A.) The two given functions are:

f(x) = (x + 2)^2 and g(x) = 3(x - 1)

Open the bracket of the two functions

f(x) = (x + 2)^2

f(x) = x^2 + 2x + 2x + 4

f(x) = x^2 + 4x + 4

and

g(x) = 3(x - 1)

g(x) = 3x - 3

To find gf(x), substitute f(x) for x in g(x)

gf(x) = 3( x^2 + 4x + 4 ) - 3

gf(x) = 3x^2 + 12x + 12 - 3

gf(x) = 3x^2 + 12x + 9

Where

a = 3, b = 12, c = 9

B.) To find g '(12), you must first find the inverse function of g(x) that is g'(x)

To find g'(x), let g(x) be equal to y. Then, interchange y and x for each other and make y the subject of formula

Y = 3x + 3

X = 3y + 3

Make y the subject of formula

3y = x - 3

Y = x/3 - 3/3

Y = x/3 - 1

Therefore, g'(x) = x/3 - 1

For g'(12), substitute 12 for x in g' (x)

g'(x) = 12/4 - 1

g'(x) = 3 - 1

g'(x) = 2.
