Answer:
these are true = 1, 3, 5
Step-by-step explanation:
overall class a scored better than class b
they're more students in class a compared to class b
If, for example, you had x on one side and x on the other, then subtracting x from both sides "disappears" x. If no other power of x shows up on either side, then your equation either has no solution or is always true.
The type of transformation that maps <span>∆ABC onto ∆A′B′C′ is a
reflection transformation
The triangle is reflected across the line y = 0.
</span><span>
When ∆A′B′C′ is reflected across the line x = -2 to form ∆A″B″C″,
B'' vertex
of ∆A″B″C″ will have the same coordinates as B′</span>
Answer:
The equation that represents the line passing through the point (2, -4) with a slope of one half is
Step-by-step explanation:
The equation of a line can be described by a first order equation in the following format:
In which a is the slope of the line.
Solution:
The line slope is 
, so 
.
The equation of the line now is:
The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4
So:
So, the equation that represents the line passing through the point (2, -4) with a slope of one half is
The number of positive and negative roots or zeros of a polynomial function is predicted through the Descartes Rule of Sign. This was first described by Rene Descartes in his work La Geometrie. The technique is for determining an upper bound on the number of positive and negative real roots.
