Equation 1. The rate of change is 3. In equation 2, you must divide each side by 2, giving you a rate of 5/2, which is 2.5. And 2.5<3
Answer:
Options B, C and D
Step-by-step explanation:
Linear pair of angles means sum of the angles of the pair is 180° which are formed at a point of a line.
In other words, pair of supplementary angles is the linear pair.
From the figure attached,
Pair of the linear angles are,
1). ∠BAC and ∠CAD
2). ∠BAE and ∠EAD
3). ∠EAD and ∠DAC
Therefore, Options B, C and D are correct.

Answer: D. y = -x</h3>
======================================================
Explanation:
Point T is at (-2,1)
When we reflect it over the line x = 0, aka the y axis, we use the rule 
so T(-2,1) becomes T ' (2, 1). The x coordinate flipped in sign, while the y coordinate stays the same.
Then the final transformation is reflecting over y = -x using the rule 
. Therefore, the point (2,1) moves to (-1, -2) which is where T'' is located in the diagram.
You apply the same two transformations for the points R and S to get R'' and S'' respectively.
Note: A composition of two reflections, where the lines of reflection aren't parallel, form a rotation. In this case, we have a 90 degree counterclockwise rotation when going from triangle RST to triangle R''S''T''.
Answer:
74 °
Step-by-step explanation:
the sum of every angle from a triangle is 180
so to find b is add 80 with 26 which is 106
then subtract 180 with 106
the final answer is 74
Answer:
1.) 3 hours 2.) 60km
Step-by-step explanation:
180km traveled in 3 hours. 180 divided by 3 = 60.
