Hurr solve 2x^2 + 8 = 0 by graphing the related function. there are two solutions: 2 and -2 there is one solution: 2 there are no real number solutions there are two solutions: (idk how to type this answer so i took a picture of it)

There are no real number solutions.

Step-by-step explanation:

Real numbers are a whole range of numbers including: Natural Numbers(1;2;3...), Whole Numbers(0;1;2...), Integers(...;-2;-1;0;1;2;...), Rational Numbers(-0.6; -0.2; 0 ;1.5 etc.) and Irrational Numbers(;;π; etc.). All these number comprise Real Numbers.

Imaginary Numbers are the square roots of negative Integers, which is the case for this question.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
