The equation 20z-5-12z = 10z + 8 have one solution i.e z=-\frac{13}{2}

Step-by-step explanation:

Finding the solutions of the equation:

20z-5-12z = 10z + 8

Solving:

20z-5-12z = 10z + 8\\8z-5=10z+8\\Adding\,\,5\,\,on\,\,both\,\,sides\\8z=10z+8+5\\8z=10z+13\\Adding\,\,-10z\,\,on\,\,both\,\,sides\\8z-10z=13\\-2z=13\\z=\frac{13}{-2} \,\,or\\z=-\frac{13}{2}

The equation 20z-5-12z = 10z + 8 have one solution i.e z=-\frac{13}{2}

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (5 points)
lara31 [8.8K]
F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.

What is the change in temperature from 15 degrees to -9 degrees? -6, 6, -24, 25
dalvyx [7]

Answer:

24 degrees

Step-by-step explanation:

The distance from 15 degrees to 0 degrees is 15, and the distance from 0 degrees to -9 degrees is 9, so then the total distance from 15 degrees to -9 degrees is (15+9 degrees) which adds up to be 24 degrees

For what value of a are the graphs of 6y=−2x+4 and 2y=ax−5 parallel? perpendicular?
nevsk [136]

Answer:

a) Parallel when a = -2/3

b) Perpendicular when a = 6

Explanation:

a)  For two parallel lines slopes are equal.

  So, 6y=−2x+4 and 2y=ax−5 parallel if they are slopes equal.

  Slope of 6y=−2x+4, comparing with y = mx + c

     So, m = -2/6 = =-1/3

  For 6y=−2x+4 and 2y=ax−5 to b parallel we have slope of 2y=ax−5 equal to -1/3

   Slope of 2y=ax−5

           m = a/2

    We have a/2 = -1/3

                    a = -2/3

b) For perpendicular lines product of slope is -1.

   So we have

               \frac{a}{2} *\frac{-1}{3} =-1\\ \\ a=6
