A line passes through the points (2,4) and (5,6) . Select Yes or No to tell whether each equation describes this line. Equation
krek1111 [17]

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{6}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-4}{5-2}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-4=\cfrac{2}{3}(x-2)

F(x)=18x+11, find f(5)
Natalija [7]

Answer:

\boxed {\tt f(5)=101}

Step-by-step explanation:

We are given the function:

f(x)=18x+11

and asked to find f(5). Therefore, we must substitute 5 in for each x.

f(5)=18(5)+11

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply 18 and 5.

f(5)=90+11

Add 90 and 11.

f(5)=101

f(5) is equal to 101.
