F(x)=1/2x+4 For R={5,6,7,8}
anzhelika [568]

Hey there!!

Remember : R = range and f ( x ) = y and y = range

R : { 5 , 6 , 7 , 8 }

( 1 ) 5 = 1 x / 2 + 4

... 5 - 4 = x / 2

... 1 = x / 2

... x = 2 = ( 2 , 5 )

( 2 ) 6 = x / 2 + 4

... 2 = x / 2

... x = 4 = ( 4 , 6 )

( 3 ) 7 = x / 2 + 4

... 3 = x / 2

... x = 6 = ( 6 , 7 )

( 4 ) 8 = x /2 + 4

... 4 = x/2

... x = 8 = ( 8 , 8 )

Hope my answer helps!

Find the volume of the given solid. under the surface z = 5xy and above the triangle with vertices (1, 1), (4, 1), and (1, 2)
Black_prince [1.1K]
So right now you see that you have x and y intercept right? Then plug those intercepts in equation that you have and solve for z. Which means z=5(1)(1) will be 5, 5(4)(1) will be 20, and 5(1)(2) will be 10. So, overall you have 5, 20, 10.
