Answer:

A)  \frac{5}{7}

Step-by-step explanation:

Use the two-points formula for the slope of a line.

We know that the points (2,-2) and (9,3) are on the line. If (a,b),(c,d) are points on a line then the slope m is defined by the equation m=\frac{d-b}{c-a}. In this case, a=2,b=-2,c=9 and d=3 then the slope is m=\frac{3-(-2)}{9-2}=\frac{5}{7}.

5. What is the multiple zero and multiplicity of f(x) = (x + 4)(x - 2)(x + 4)(x + 4)?
natali 33 [55]

The zeros of this functions are -4, 2, -4, and -4.

-4 is a multiple zero and has multiplicity 3.

2 is a zero.  I would call it a simple zero, since it's only a zero once (AKA has multiplicity of 1).

Is this a "pick one answer" or "pick all correct answers"?

blondinia [14]

1) in first place you need to Know what kind of figure is it, in order to find solve the problem, as you can see it is a parallelogram, and the condition for this geometric figure the opposites  are equal ,

2) if you have a non -rectangular parallelogram and draw a diagonal  from A to C, you obtain two equal triangles, for this reason the line AC IS CALLED DIAGONAL,  and divide the parallelogram

3) in first place to determine that the angles are congruents for two triangles the Diagonal is comun for both, and the vertex  ∡CAB IS THE SAME ∡ACD

4) If the diagonal AB AND CD are equal , AD AND BC are equal too, then the triangles are congruent

5)  segment AB Parallel to CD THEY HAVE THE SAME SLOPE AND MAGNITUDE
