Answer:
2(x-3) = y
Step-by-step explanation:
y = 1/2 x +3
To find the inverse, exchange x and y and then solve for y
Exchange x and y
x = 1/2y +3
Then solve for 3
Subtract 3 from each side
x-3 = 1/2 y -3+3
x-3 = 1/2 y
Multiply each side by 2
2 (x-3) = 1/2 *2 y
2(x-3) = y
This is the inverse
Since they are opposite angles about the intersection of two straight lines they are equal angles....
5x+12=6x-10 subtract 12 from both sides
5x=6x-22 subtract 6x from both sides
-x=-22 divide both sides by -1
x=22°
So those angles are 5*22+12=122°
Now HJI is an adjacent angle so it is 180°-122°=58°
Answer:
B′C′ = 2
Step-by-step explanation:
BC is congruent with B′C′ , so they are the same length
