Answer:

39

Step-by-step explanation:

f(x) = 2x - 1.....(1) \\ g(x) = 3x + 5....(2) \\ plug \: x = 5 \: in \: (2) \\ g(5) = 3 \times 5 + 5 = 15 + 5 = 20 \\  \therefore \: f(g(5)) = 2 \times 20 - 1 = 40 - 1 = 39 \\  \\   \huge \red{ \boxed{\therefore \: f(g(5)) =39}}

Which equation represents the line through (4, 5) and (0, 3)?
morpeh [17]

Answer:

I dont know what options you have but all these are possible answers

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

y - 3 = 1/2 x

y = 1/2 x + 3

Step-by-step explanation:

In order to find the equation you need a slope, so you find the slope of both points by using the slope equstion

y2 - y1 / x2 - x1

and you would get :

\frac{1}{2}

now you plug it into the point slope formula  which is y - y = m ( x - x )

and you choose one of the two sets of points that they provided in the question but you'll get the same answer either way.

Draw a line representing the "run" and a line representing the "rise" of the line. State the slope of the line in simplest form.
Shtirlitz [24]

Answer:

\displaystyle 1\frac{1}{3}

Step-by-step explanation:

[3, 1] and [0, −3]

\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{3 + 1}{0 + 3} = \frac{4}{3} = 1\frac{1}{3}

I am joyous to assist you anytime.
