Let's find (f - g)(x) :

[tex]3x + 10 - (4x - 2)[/tex]

[tex]3x + 10 - 4x + 2[/tex]

[tex] - x + 12[/tex]

Answer:

f(x) = 3x + 10g(x) = 4x - 2

(f - g)(x) = f(x) - g(x)

(f - g)(x) = (3x + 10) - (4x - 2)

(f - g)(x) = 3x + 10 - 4x + 2

(f - g)(x) = - x + 12

(f - g)(x) = - x + 12 is the right answer.

If R is the midpoint of QS, QR = 6x – 51 and RS = 2x – 7, find QS.

Answers

Answer:

QS = 30

Step-by-step explanation:

Since R is the mid point QR = RS

Given QR = 6x – 51 and RS = 2x – 7 then

6x – 51 =  2x – 7, isolate like terms

  6x -2x = 51 -7 , combine like terms

        4x = 44, divide both sides by 4

         x = 11

QS = QR + RS

QS = 6x -51 +2x -7 , combine like terms

QS = 8x - 58, substitute x= 11 in the equation

QS = 8*11 -58, multiply 8 and 11

QS = 88 -58

QS = 30

If (h + h) · (h. h) = 16, find the value of h.
— HELP ME PLEASEEEE

Answers

Answer:

h = 2

Step-by-step explanation:

I'm assuming your periods are multiplication signs.

(h + h) X (h X h) = 16

When adding two variables like the first set of parentheses, it would become 2h.  When multiplying two like variables, you add the exponents.  h is the same as writing h¹.  So h¹ x h¹   gives you the answer of h².

So now your equation would look like:

2h  X  h²  = 16

As above, when you multiply two like variables you would add the exponents.  Also if any number are in front of the variable you would multiply those numbers.  So you have 2h¹ x 1h² and that would be 2h³.  If it had been

2h¹ x 2h², your answer would have been 4h³.

But so far you have 2h¹ x 1h² = 16

2h³ = 16

Dividing both sides by 2 you get

h³ = 8

To find h you have to take the cubed root of 8.  What number multiplied by itself 3 times gives you 8?    2 x 2 x 2 = 8     2 x 2 = 4 and x 2 = 8.

h = 2

If you put this into the original equation you have:

(2 + 2) x ( 2 x 2) = 16

 ( 4 ) x ( 4 ) = 16
