Identify the composition with rotation to map ΔABC onto ΔA′B′C′ in the given figure. A. Reflection across the x-axis; 180° counterclockwise rotation about the origin
B. Reflection across the y-axis; 90° counterclockwise rotation about the origin
C. Reflection across the x-axis; 270° counterclockwise rotation about the origin
D. Reflection across the y-axis; 270° counterclockwise rotation about the origin

it is x=-4

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

i think the answer is 90 hope this
