Find the Value of expression ( screenshot below)

6

Step-by-step explanation:

Substitute x=4 and y=6 into the expression.

=[4(4)-12] + [1/2(4) (6) -10]

=(16-12)+(1/2(24)-10)

=4+2

=6

Have a great day!

6

Step-by-step explanation:

Sub in the values for the variables and solve

= 4(4) - 12 + 1/2(4)(6) - 10

= 16 - 12 + 12 - 10

= 6

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
