Sometimes when you’re doing math, it’s easier to line your numbers up when you have your ratio as a decimal! Hope it helped
-10y^2 + (-3y^2) - 4y^2 - (-6y^2) =
-10y^2 - 3y^2 - 4y^2 + 6y^2 =
-17y^2 + 6y^2 =
- 11y^2
Answer:
The correct answer for this is : A. Point and Line
Step-by-step explanation:
The lines are said to be parallel to each other if they do not intersect each other at any point. So, for any number of lines to be parallel we must have lines and no intersection points between them then only we can say the given number of lines are parallel to each other
So, the terms which are used to explain the term parallel lines here are : line and the point.
And the both terms point and a line are undefined in the geometry.
Hence, the correct answer for this is : A. Point and Line
Answer:
Step-by-step explanation: 3a-5b= 3(7)-5(4)
=21-20
=<u>1</u>
7-3a+5a+15=7-3(7)+5(7)+15
=7-21+35+15
=-14+50
=<u>36</u>
15a^2-17(bc)^2=15(7)^2-17(4)(-3)^2
=105^2-204^2
=210-408
=<u>-198</u>
