You know the factor of 2 will make the result have even numbers. Thus C and D are immediately eliminated. To tell whether the answer is A or B, you only need to find the second number.
.. 2*(1*0 +2*(-1)) = -4
The appropriate selection is ...
B. [14 -4]
Answer:
9. x = 5
10. AD = 7
Step-by-step explanation:
As shown in the diagram, BD is a perpendicular bisector. And D is a point on the perpendicular bisector, meaning it is equidistant from the endpoints on the segment(points A and C). Because of this, we can say AD = CD.
We can substitute to get:
2x - 3 = x + 2
And simplify and solve:
x - 3 = 2
x = 5
AD is just 2x - 3, so we can substitute in x to find AD:
AD = 2(5) -3
AD = 10 - 3
AD = 7
Restrict values of x to

. Then the surface area function is one-to-one and has an inverse.
Write y instead of S(x). Interchange x and y, then solve for y.

This function could be used to find the edge of a cube with a given surface area. For example, if the area is x = 54, then the edge is
