Answer:
Option (1)
Step-by-step explanation:
Quadratic equation is given as,
2x² + 8 = 0
Let the function is,
f(x) = 2x² + 8
f(x) = 2(x - 0)² + 8
Now we will prepare the table for every input value,
x -2 -1 0 1 2
y 16 10 8 10 16
By plotting these points we get a parabola having vertex at (0, 8).
Graph of the given function doesn't touches or intersects the x-axis.
And we know if a graph has no x-intercept, function graphed will have no real solution.
Therefore, function f(x) will have no real solutions.
Option (1) will be the answer.
Answer: Candace ate servings.
Step-by-step explanation:
Given: Candace ate cup of cereal.
The box of cereal states that 1 serving of cereal = cup.
i.e. 1 cup = servings [Multiply
both sides]
⇒ cup =
servings
= servings [which is the number of servings she ate]
Hence, Candace ate servings.
Solving the system of equations, it is found that x = 3, that is, there are 3 128 MB memory sticks.
--------------------
We want to solve for x, thus, in the first equation, we write y as a function of x, that is:
Replacing in the second equation:
x = 3, that is, there are 3 128 MB memory sticks.
