An even number between 7 and 16 could be 8, 10, 12, or 14. You know they are even number because they always end with a digit of 2, 4, 6, 8, or 0. Also it is divisible by 2. Just draw a number line.<span />
Expand and multiply
3^5 = 3 x 3 x 3 x 3 x 3 = 9 x 9 x 3 = 81 x 3 = 243
243 is your answer
hope this helps
Amanda used 15%
Rose used 0.17
Multiply the decimal by 100 to get the percentage:
0.17 x 100 = 17%
Hannah used 16/25
Divide 16 by 25 to get a decimal then multiply by 100 to get the percentage:
16/25 = 0.64 x 100 = 64%
64% is greater than 15% and 17% so Hannah used the most.
Answer:
Well, first you'd want to isolate your Ys, so that
-3y≤12-2x
&
y≥1-2x
Now they look like your common (y=mx+b) equations, so you should be able to graph from there. I don't quite remember how the shadowing works for inequalities, SO, go to desmos.com, type in the equations, and voila!
Perpendicular lines are lines that intersect and parallel line are lines that are parallel to each-other and never intersect
