Answer:

x = 5

Step-by-step explanation:

Given

f(x) = 4x - 2 and f(x) = 18 , equating both gives

4x - 2 = 18 ( add 2 to both sides )

4x = 20 ( divide both sides by 4 )

x = 5

I need help please if m<MNR=43 and m<MNP=84 find: m<RNP​ subtract or add
Zielflug [23.3K]

Answer:

  41°

Step-by-step explanation:

The angle addition theorem tells you ...

  m∠MNR + m∠RNP = m∠MNP

Filling in the given values, you have ...

  43° + m∠RNP = 84°

Subtract 43° from both sides of the equation to find the angle of interest:

  m∠RNP = 84° - 43° = 41°

The measure of angle RNP is 41°.

Factor -1/4 out of -1/2x -5/4y. (i will mark brainlyest)
mash [69]

Answer:

-1/4 (2x - 5y)

Step-by-step explanation:

For us to factor -1/4 out of -1/2x -5/4y

We will have to multiply the values in bracket by the reciprocal of -1/4 i.e -4 as shown

-1/2x - 5/4 y

= -1/4 (-4(-1/2x) - (-4)(-5/4y))

= -1/4 (4/2 x - 20/4 y)

= -1/4 (2x - 5y)

Hence the factored expression is -1/4 (2x - 5y)
