Nina [5.8K]3 years ago

Answer:

a=-85/4

b=53/4

Step-by-step explanation:

17x(5+a)=17xb+221. (1)

85+17xa=17xb+221

85+(17xa)-(17xb)-221=0

17xa-17xb=-136

17x(a-b)=-136

a-b=-8

a=-8+b. (2)

Replace a=-8+b to (1):

17x5x(-8+b)=17xb+221

85x(-8+b)=17xb+221

-680+85xb=17xb+221

-680+85xb-17xb-221=0

-68xb-901=0

-68xb=901

b=-53/4

Replace b=-53/4 to (2):

a= -8+(-53/4)= -85/4

How is a trapezoid similar to a parallelogram
Svetllana [295]
Trapezoid and paralellogram are both quadrilaterals

the heiarchy is
quadrilaterals are 4 sided figures
quadrilaterals is split up into
      A. no pairs of paralell sides
             - kite
       B. 1 pair of paralell sides
               - trapezoid/trapezium
      C. 2 pairs of parell sides (paralellograms)
           -rectangles
           -rhombus
           -square


so you can see that they are both quadrilaterals (quad=4, lateral=sides, quadrilateral=4 sided figure)

Please help!!

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other

Given the functions expressed as:

h(x) =\sqrt{2x+2}\\g(x)\frac{x^2-2}{2}  \\

In order to check whether they are inverses of each other, we need to show that h(g(x)) = g(h(x))

Get the composite function h(g(x))

h(g(x))=h(\frac{x^2-2}{2} )\\h(g(x))=\sqrt{2(\frac{x^2-2}{2} )+2}\\h(g(x))=\sqrt{x^2-2+2} \\h(g(x))=\sqrt{x^2}\\h(g(x))=x

Get the composite function g(h(x))

g(h(x))=\frac{(\sqrt{2x+2} )^2-2}{2} \\g(h(x))=\frac{2x+2-2}{2}\\g(h(x))=\frac{2x}{2}\\g(h(x))=x

Since g(h(x))=h(g(x))= x, hence functions h and g are inverses of each other
