Answer:
C. both student 1 and student 2
Step-by-step explanation:
Dilation does not change any angles, so the triangles are similar and the trig functions of corresponding angles will be identical.
The slope of CB is -1/3 and the slope of BA is 3, so they multiply together to give -1. That means the segments are at right angles and the triangle is a right triangle.
Both the premise and the conclusion of each student is correct.
You have to use the distributive property, therefore you get 2x+13/3.
The next step is to do 2 x 5 because they gave us a number for the variable x. Then you have to do 2 x 13 which gives us 26.
10+26=36 and 36/3=12, hope I helped, Have a nice day! :)
Answer:
r>4
Step-by-step explanation:
-3r+5<-7
-3r+5-5 <-7-5
