Step-by-step explanation:
f(x) = x² + x + 3/4
in general, such a quadratic function is defined as
f(x) = a×x² + b×x + c
the solution for finding the values of x where a quadratic function value is 0 (there are as many solutions as the highest exponent of x, so 2 here in our case)
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 1
c = 3/4
x = (-1 ± sqrt(1² - 4×1×3/4))/(2×1) =
= (-1 ± sqrt(1 - 3))/2 = (-1 ± sqrt(-2))/2 =
= (-1 ± sqrt(2)i)/2
x1 = (-1 + sqrt(2)i) / 2
x2 = (-1 - sqrt(2)i) / 2
remember, i = sqrt(-1)
f(x) has no 0 results for x = real numbers.
for the solution we need to use imaginary numbers.

Answer:
A, B and E
Step-by-step explanation:
A proportional relationship has the form
y = kx ← k is the constant of proportionality
The only equations in this form are
A, B and E
1. plug in the numbers for the variables, like this: 9(-5)+18(-1)
2. solve

Answer:
well you just get 32
Step-by-step explanation:
but i divide 16 divide 5 and got 3.2 so it might be an extra .2 stickers
