The question is in the picture please help fast
Marrrta [24]

Answer:

<em>y = 4x - 57 </em>

Step-by-step explanation:

( x_{1} , y_{1} )

( x_{2} , y_{2} )

m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

y - y_{1} = m ( x - x_{1} )

~~~~~~~~~~~~~~~

( 15 , 3 )

( 19 , 19 )

m = \frac{19-3}{19-15} = 4

y - 3 = 4 ( x - 15 )

<em>y = 4x - 57</em>

Given f(x) = 3x- 1 and g(x) = 2x-3, for which value of x does g(x) = f(2)?
Vedmedyk [2.9K]

Answer: x = 4

Step-by-step explanation: f(2) = 3(2)-1 = 5. Meaning x needs to be a value that makes g(x) = 5. You can set them up equal to each other 5 = 2x-3 and solve. You end up getting x = 4.
