Answer:

x=1

Step-by-step explanation:

5x-(x+1)=5-2x

distribute

5x-x-1 = 5-2x

4x-1 = 5-2x

add 2x on each side

4x-1+2x = 5-2x+2x

6x -1 = 5

add 1 on each side

6x-1+2 = 5+1

6x = 6

divide by 6

6x/6 = 6/6

x = 1

f(g(11)) = -6

Solution:

Given data:

$f(x)=x^{2}-6 x+3$

$g(x)=\sqrt{x-2}$

To find f(g(11)):

Substitute x = 11 in g(x).

$g(11)=\sqrt{11-2}$

$=\sqrt{9}$

$g(11)=3$

Substitute g(11) = 3 in f(g(11)).

$f(g(11))=f(3)$

$f(x)=x^{2}-6 x+3$

$f(3)=3^{2}-6 (3)+3$

$f(3)=9-18+3$

$f(3)=-6$

$f(g(11))=f(3)$

= -6

Hence f(g(11)) = -6.

What is the greatest common factor of 60, 45 and 82? HALPPPPPPPPPPPPPPPPPPp

son4ous [18]

Answer:

GCF: 1

Step-by-step explanation:

Factors are numbers that can be evenly divided into another number. The greatest common factor of a set of numbers is the biggest number than can evenly divide into all the the numbers.

Let's list the factors of 60, 45 and 82

Factors of 60:

1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Factors of 45:

1, 3, 5, 9, 15, 45

Factors of 82:

1, 2, 41, 82

The greatest factor that all 3 numbers share is 1.

lesantik [10]

Answer:

A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

Simplify them again by dividing them both by 2

= 49

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215 and 25

Simplify by dividing by 5

= 43

Now that its simplified you can compare

43 is smaller than 49

5 5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

Make 51 and 49 have the same denominator so we can compare them

10 5

51 can stay the same because 5 times 2 equals 10

49 times 2

5 times 2

= 98

Now that the denominators are the same we can compare

51 is much smaller than 98

10 10

Therefore, C is also not proportional.

Hope that helps :D
