Answer:
-7/48
Step-by-step explanation:
- Ok, so if there is a change of -7/16 inches every 3 years, then you just basically have to divide -7/16 inches by 3. And since you can't divide fraction and only multiply the reciprocal of a fraction you would say -7/16 * 1/3 = -7/48.
- If you want to mark it on a number line, you would basically just find -7/16 and divide the distance from 0 to -7/16 into 3 portions and mark the 1st third of the distance your answer.
Answer:
5. A.
6. F
Step-by-step explanation:
5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3
y = 3x + b
using coordinates (-6,3)
3 = 3(-6) + b
b = 21
y = 3x + 21
6. I think F is the right answer
Answer: y=-6
Step-by-step explanation:
y = -4 when x = 1
find y when x = 3
y=-4 x=1
y=-5 x=2
y=-6 x=3
im not sure if this is right so I’m sorry
Answer: 43
Explanation: All triangles add up to 180. We can subtract angle Z to get 86. Since X and Y are equal, we can divide 86 by 2.
