Answer:
A) y = x^2 -1
B) -y = 2x^2 +1 We multiply B) by -1
B) y = -2x^2 -1
We can then say x^2 -1 = -2x^2 -1
3 x^2 = 0
x = 0
************* Double-Check: ******************
Equation A) y = -1 and
Equation B) y = -1
Step-by-step explanation:
The expression 6x^2 will have the shape of a parabola when graphed
<h3>What are quadratic equations?</h3>
Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
<h3>How to determine the shape of 6x^2 when it is graphed?</h3>
The function expression is given as:
6x^2
Express the function as an equation.
So, we have
y = 6x^2
The above equation is a parabola or a quadratic equation.
All quadratic equations have the same shape and the shape is parabola
This means that the expression 6x^2 will have the shape of a parabola when graphed
Hence, the expression 6x^2 will have the shape of a parabola when graphed

Answer:
A) Cross-sectional
Step-by-step explanation:
A cross-sectional study is a type of study that involves the data i.e. taken from a population for a specific time period.
Here study shows the peoples interest in variables that are be chosen
In the given situation, since a town obtains a data of the current employment for 10,000 of its total citizens
So this represents the cross-sectional
hence, the correct option is A.

The graph required to answer this question is not provided. However, the information that will be provided in this explanation will be sufficient to answer the question.
Since the two paths are perpendicular, they can be seen as the x and y axes.
Let your school to the library indicate the x direction and the path from your home to the pack be the y-axis.
if your school = x1
Library = x2
home = y1
park = y2
The slope, m, can be calculated using m = (y2 - y1)/(x2 - x1)
After getting the slope, the equation can then be modelled as the equation of a line.
y - y1 = m(x - x1)
Inserting the values of x1 and y1 will give the required equation.
