Acompany ls selecing students for interviews at the career tair. the number of students selected trom university a is gnen by t)x+& where x represents the number of days of the tair. the number of students selected from unversity b is given by g) 2x+8

If this is the question:

Which function best describes the total number of students selected at the career fair?

The answer is h(x)= 6x+ 13.

there is no grid

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
