Answer:
1: proportional
2: non-proportional
3: non-proportional
4: non-proportional
5: proportional
6: proportional
7: non-proportional
8: proportional
9. proportional.
10. proportional.
11. non-proportional.
12. proportional.
Step-by-step explanation:
I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.
Answer:
52 cm^2
Step-by-step explanation:
To find the rectangular area on the bottom you multiply 3 by 5 = 15 cm^2.
To find the triangular area on the sides you multiply 4 by 3 = 12 cm^2 then divide by 2 = 6 cm^2, but since there are 2 of them you multiply by 2 again and end up with a surface area of 12 cm^2.
To find the square area on the top you multiply 5 by 5 = 25 cm^2.
So the total surface area is 25+15+12 = 52 cm^2.
<em>Note: cm^2 represents cm squared</em>
As a rule, you plot the lines as though the equations had an equal sign. Because both are strict inequalities (no "or equal to"), the lines are dashed, indicating the (x, y) values on the line are NOT part of the solution.
The solution space will be above the first line (y > ...) and below the second line (y < ...). As a rule, you indicate the solution space by shading the portion of hte plane that satisfies the inequality.* The solution is the portion of the plane that is in both solution regions (that is, doubly-shaded).
_____
* Sometimes, it may actually work better to shade the portion of the plane that does NOT satisfy the inequality. That way, the remaining unshaded area is the solution space. If you do it that way, make sure the graph is clearly marked indicating that is the case. The usual expectation is that the shaded area is the solution, so you don't want to get your answer marked wrong or misinterpreted.
