From what I remember it is -x-31y
That would be 1.... you can ask Siri btw xD
A + 4 = s
2(a+2) = (s+2)
plug in the upper equation into the lower equation
2(a+2) = (a+4+2)
2a+4 = a+6
a+4 = 6
a = 2 years old
To find the rule of translation, find the change of corresponding coordinates. In this graph, for example see how A is moved to A': three units to the right, then two units down. A(-4,3)+(3,-2)=A'(-1,1). This applies to the whole shape, and is the rule of translation.
Answer:
last choice
Step-by-step explanation:
sin(theta) is positive
tan(theta)=sin(theta)/cos(theta) is negative
If sin(theta) is positive and tan(theta) is negative, then cos(theta) is negative because +/-=-
So we are looking for the quadrant where sine is positive and cosine is negative or when x is negative and y is positive.
This is in quadrant 2 so our angle theta is between 90 and 180 degrees.
