Topic: Linear Inequalities in 2 variables (Freshman in high school level)
This is the last question on my assignment so help would be appreciated.
The authors of a nutritional study conclude that the fat calories consumed per day
should be at most 30% of the total calories consumed per day. Write and graph
an inequality that describes this conclusion. Identify and interpret one of the
solutions.

No need to graph it, just an equation would help, thank you.

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

i use my brain for prombles like this maybe you could try it
