Answer: A
Step-by-step explanation:
Convert degrees to radians, multiply by π/180° , since a full circle is 360 ° 360 or 2π radians.
− 405°⋅ π /180° radians
Cancel the common factor of 45 .
-9 ⋅ π/4 radians
Combine −9 and π/4
-9π/4
Move the negative in front of the fraction.
-9π/4 radians
G(x)=x+7 is the translation
Answer:
y=6
x=6.42
Step-by-step explanation:
7(-9)+9y=-9
-63+9y=-9
+63 +63
9y/9=54/9
y=6
7x-9(6)=-9
7x-54=-9
+54 +54
7x/7=45/7
x=6.42
