Which of the following is equivalent to (2a? -6ab +43?)-(-a' +2ab - 28?)? A. (20? - bab+432)+(a? - 2ab- 262)
B. (-20° +6ab-433)+(c? - 2ab +233)
C. (2a- 6ab+43°)+(-a?- 2ab +233)
D. (20- 6ab+483)+(a? - 2ab +232)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.
