Answer:
30 + 5<em>d</em> ≥ 120
Step-by-step explanation:
One ticket costs $120 and she already has $30 saved up so the money she makes by dogwalking added to the $30 has to be equal to or greater than 120
- 30 for the <u>amount she saved up</u>
- 5<em>d</em> where <u><em>d</em></u><u> stands for the number of days she walks dogs </u>
- Make this information into one part of the inequality: 30+5<em>d</em>
- Then this has to be greater than or equal to 120 so:
<u>30+5</u><em><u>d</u></em><u>≥120</u>
Hope this helps!
Triangle JKL was rotated 90° counterclockwise and then refrected across the line y = -4.
Answer:
No
Step-by-step explanation:
Using the converse of Pythagoras' identity
If the longest side squared is equal to the sum of the squares of the other 2 sides then the triangle is right.
31² = 961
16² + 30² = 256 + 900 = 1156
Since 961 ≠ 1156 then the sides do not form a right triangle.
