How many solutions are possible for a system of equations containing exactly one linear and one quadratic equation? (Select all
galina1969 [7]
Remember that a quadratic equation is a parabola. The equation is of the type y = Ax^2 + Bx + C


A linear equation is a straight line. The equation is of the type y = MX + N


The soluction of that system is Ax^2 + Bx + C = MX + N

=> Ax^2 + (B-M)x + (C-N) = 0


That is a quadratic equation.


A quadratic equation may have 0, 1 or 2 real solutions. Those are all the possibilitis.


So you must select 0, 1 and 2.


You can also get to that conclusion if you draw a parabola and figure out now many point of it you can intersect with a straight line.


You will realize that depending of the straight line position it can intersect the parabola in none point, or one point or two points.

ArbitrLikvidat [17]

Answer: average time in minutes that it will take to drive from campus to workplace

Step-by-step explanation:

The dependent variable refers to the variable that the researcher is testing or measuring in an experiment. Let's say for example, we want to know the impact of reading on the examination score of a student. In this case, the dependent variable will be the examination score of the student since that's what we're measuring.

With regards to the question, the dependent variable is average time in minutes that it will take to drive from campus to workplace.

Number 18 and 20 thank you
Afina-wow [57]
18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.

20.) The formula for the area of a parallelogram is:
A = b • h

110.5 = 13h

110.5 / 13 = 8.5

110.5 = 13 • 8.5

And because this is a measurement of the height, not the area, it is just meters (m)

So, the full answer is 8.5 m

I hope this helps!
