Step-by-step explanation:
Figure B appears to be a reflection of Figure A across the origin. Such a reflection can be described by any of ...
- reflection across the origin
- rotation 180° CW about the origin
- rotation 180° CCW about the origin
- reflection across the x-axis followed by reflection across the y-axis
- reflection across the y-axis followed by reflection across the x-axis.
Answer:
Soda costs $1.15 and taco costs $0.95.
Step-by-step explanation:
x + y = 2.1
2x + 3y = 5.15
Multiply the first equation by -2 to eliminate x
-2x - 2y = -4.2
2x + 3y = 5.15
Add
y = 0.95
Find x with the original first equation
x + y = 2.1
x + 0.95 = 2.1
x = 2.1 - 0.95
x = 1.15
hope it helps :)

Answer:
22, 19, 16 and - 5
Step-by-step explanation:
To evaluate any term from the n th term formula substitute the terms position value for n
given
= 25 - 3n, then
(a)
= 25 - (3 × 1) = 25 - 3 = 22
= 25 - (3 × 2) = 25 - 6 = 19
= 25 - (3 × 3) = 25 - 9 = 16
(b)
= 25 - (3 × 10) = 25 - 30 = - 5
Answer: B
