Option A, x < 0

When looking at line graphs, it's relatively easy to figure out how they work.

Start by locating where the point is. In this case, the point is on 0. Now, is the point hollow? If it is, then you know that the inequality is either < or > (if it's hollow, it means that the integer isn't included). However, if the circle's filled in, you know that it's either ≥ or ≤ (if the circle's filled in, the integer is included)

Now, check to see which way the line goes. Does the number get smaller or bigger as you go across the line? If the number gets bigger, then x > 0. If the number gets smaller, then x < 0.

Which of the following is equivalent to the

s344n2d4d5 [400]

Step-by-step explanation:

$= {i}^{31}$

$= {i}^{28} \times {i}^{3}$

$= {( {i}^{4} )}^{7} \times ( {i}^{2} \times i)$

$= ( {i}^{2} \times {i}^{2} ) {}^{7} \times {i}^{2} \times i$

$= ( - 1 \times ( - 1)) {}^{7} \times ( - 1) \times i$

$= {1}^{7} \times ( - i)$

$= 1 \times ( - i)$

$= - i$

The answer is D.

For each shape in the table, list three examples of real-world objects that could be modeled by the shape. Use your experiences,

marishachu [46]

Interesting question. Let's see.

Rectangular Prism: any box (like a shoe box or a packing box).

Triangular Prism: We're not supposed to give personal answers, but I can't help it with this. When I was growing up, our front door's window had a triangular prism beveled around its edges. What made it so remarkable was that it broke up the light into a rainbow of colors on the floor.

Cylinder. Many drinking glasses are in the shape of a cylinder. Also old fashioned water towers were cylindrical in shape.

Cone: a kitchen funnel is an upside down cone. Some funnels don't have a spout, so that makes them true cones.

Pyramid: The pyramids for the Pharaohs in Egypt.

Sphere: Any ball (beach ball, baseball basketball soccer. Some storage shapes for spices -- technically not a perfect sphere). Planets. The sun. (The earth is almost a perfect sphere).
