Answer:

  d.  14 -3x

Step-by-step explanation:

If you want to substitute for y in the second equation, you must use the first equation to find an expression for y.

  3x +y = 14 . . . . . . first equation

  y = 14 -3x . . . . . .  subtract 3x from both sides

This gives you the expression for y that you want to use for substitution. It matches the expression of choice D.

  y = 14 -3x . . . . matches D

Help Pre-Calc
Alex73 [517]

Answer:

B) vertical stretch

Step-by-step explanation:

Given that the cost of manufacturing x refrigerators is given by the function f(x)= 2x^2 + 6000.

Now it says that the cost doubles for the year 2011 owing to higher raw material prices. So that means cost function will change from f(x) to 2f(x).

Now we need to decide the type of transformation from f(x) to 2f(x).

Remember that when f(x) changes to a*f(x) where value of "a" is greater than 1 then it stretches the function vertically by factor of "a".

in 2f(x), we have a=2

So that means "B) vertical stretch" is the correct choice.

Point M is between points L and N on segment LN. LM=5x, MN=2x+4, and LN=10x-16
nadezda [96]

Answer:

x= 6.6

LM= 33

MN= 17.2

LN=50

Step-by-step explanation:

10x-16= 5x+2x+4 (LN=LM+MN)

10x-16=7x+4

3x-16=4

3x=20

x=6.6

then plug 6.6 back into equation and round to the nearest whole number.
