Write an equation in slope-intercept form, y = mx+b, using the given
likoan [24]

Answer:

y = \frac{-4}{3}x - 15

Step-by-step explanation:

with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m

y - y2 = m(x - x1)

y - (-3) = -4/3 (x - (-9))

y + 3 = -4/3 (x + 9)

y + 3 = -4/3 x + -12

y = -4/3 x - 12 - 3

y = \frac{-4}{3}x - 15

The function F is defined by F(x)= 12/x + 1/2 . Use this formula to find the following values of the function.
IgorLugansk [536]

Answer:

F(3)=\frac{9}{2} \\F(-12)=\frac{-1}{2} \\F(\frac{1}{3} )=\frac{73}{2} \\F(\frac{3}{4} )=\frac{33}{2}

Step-by-step explanation:

Given: F(x)= \frac{12}{x}  + \frac{1}{2}

To find: Values of the function F(3) , F(−12) , F(\frac{1}{3}), F(\frac{3}{4})

Solution:

A function is a relation in which each and every element of the domain has a unique image in the co-domain.

To find the values of the functions F(3),F(-12),F(\frac{1}{3} ),F(\frac{3}{4} ), put x=3, -12, \frac{1}{3},\frac{3}{4} in the given function F(x)= \frac{12}{x}  + \frac{1}{2}

F(x)= \frac{12}{x}  + \frac{1}{2}\\F(3)= \frac{12}{3}  + \frac{1}{2}\\=4  + \frac{1}{2}\\=\frac{9}{2}

F(x)= \frac{12}{x}  + \frac{1}{2}\\F(-12)= \frac{12}{-12}  + \frac{1}{2}\\=-1+\frac{1}{2}\\ =\frac{-1}{2}

F(x)= \frac{12}{x}  + \frac{1}{2}\\\\F(\frac{1}{3} )= \frac{12}{\frac{1}{3}}  + \frac{1}{2}\\=36+\frac{1}{2}\\ =\frac{73}{2}

F(x)= \frac{12}{x}  + \frac{1}{2}\\\\\\F(\frac{3}{4} )= \frac{12}{\frac{3}{4}}  + \frac{1}{2}\\\\=16+\frac{1}{2}\\ \\=\frac{33}{2}
