Step-by-step explanation:
Assuming that the 270° rotation is in a clockwise motion,
A point (a, b) which undergoes such a rotation will have the new point (-b, a).
Since we have A(2, 1),
A' has the coordinates (-1, 2).
translate, call the number, n
Eight more than (8+) twice a number increased by 3 (2(n+3)) is equal to (=) 79 (79)
8+2(n+3)=79
minus 8 both sides
2(n+3)=71
divide both sides by 2
n+3=35.5
minus 3 both sides
n=32.5
the number is 32.5
Answer:
9x2+4x−14
Step-by-step explanation:
The angle RSV would be 42°
D. You start out with $500, it does not use a variable, knocking out a and b. Also, you need at least the needed amount of money, so b or c cannot be the answer. This only leaves d.
