Answer:
B. 3/2
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals
The negative reciprocals of -2/3
is 3/2
It would be: Kn + 4f = 9
kn = 9 - 4f
n = (9-4f) / K
Hope this helps!
Answer:
Step-by-step explanation:
So we multiply 7 by 4, and get 28. Then we multiply 2 by 12, and get 24. Next we give both terms new denominators 12 × 4 = 48.
Answer : 7 or 7/1
step by step explanation:
Answer:
Step-by-step explanation:
4y - 2(5 - y + 4) = 4y - 2(9 - y)
= 4y + 9*(-2) - y *(-2)
= 4y - 18 + 2y {Combine like terms 4y and 2y}
= 6y - 18
6y - 18 = 6*y - 6*3
= 6(y - 3)
6y- 18 = 2 *3y - 2*9
= 2(3y -9)
2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)
Others are not equivalent
