Answer (2)
Step-by-step explanation:Here’s how to graph each of the given equations:1. Rearrange to slope-intercept form:Solve for :2y = 8 - 3x \implies y = 4 - \frac{3}{2}x-intercept (when ): -intercept (when ): Plot points: (0, 4) and (2.67, 0) and draw the line.2. This equation seems incorrect as it suggests two equalities. It can be interpreted as two separate equations:From :x = \frac{6}{4} = \frac{3}{2} = 1.5y = \frac{6}{2} = 3So, this gives the points and .3. Rearrange to slope-intercept form:Solve for :y = 1 - 5x-intercept (when ): -intercept (when ): Plot points: (0, 1) and (0.2, 0) and draw the line.Summary of Points to Plot:1. : (0, 4) and (2.67, 0)2. : (1.5, 0) and (0, 3)3. : (0, 1) and (0.2, 0)You can graph these points on a coordinate plane and draw the lines accordingly.
6. A. oxygen - Body wastes are substances that the body needs to get rid of. Urine, carbon dioxide (from breathing out), and undigested food (in feces) are all wastes. Oxygen is essential for the body and is taken in, not expelled as waste.7. D. starfish - Monkeys, frogs, and fish all have backbones (vertebral columns) and internal skeletons, making them vertebrates. Starfish are echinoderms and have a different type of skeletal structure.8. C. They estivate or bury themselves in the mud and come out only when the rain comes. - Estivation is a period of inactivity and slowed metabolism in some animals during hot and dry periods. Hibernation is similar but occurs during cold periods. Mudfish, frogs, and snails often bury themselves in mud to stay moist during the dry season.9. B. They produce poisonous substances to drive away their enemies. - While some beetles have hard coverings, and snakes might have sharp teeth, the most common defense mechanism listed for snakes (venom), skunks (odor), and some bugs is the production of poisonous or noxious substances to deter predators.
