Answer:
around 22, or 21.98
Step-by-step explanation:



Remember:
a) (x,y) => (x, -y) is a reflection across X axis
b) (x,y) => (-x,y) is a reflection across Y axis
Here △RST is mapped to △R′S′T′ using the rule (x,y)→(x,−y)
Hence it is a reflection across X axis.
The size of the triangle does not alter.
But when this is followed by (x,y)→(3x,3y), the lengths increase by a factor 3.
Hence the triangles do not remain congruent.
△RST is not congruent to △R′S′T′ because the rules do not represent a sequence of rigid motions.
Option A) is the right answer
10n-4=126
Step-by-step explanation:
I hope this is right, so number would be a variable (n) because we don't know what said number is.
if your multiply that by 10 then put the 10 next to variable, like usual. at least that's what I do.
four less would be saying to subtract 4
and the final answer is 126
Answer:
it already is less than $675
Step-by-step explanation:
if u multiply 20% by 3 then put it into decimal form, you get .60 which then u can then multiply that by $2500 and get $417
( might be wrong :'(
