87
Step-by-step explanation:
We are looking at the numbers up side down
the number on the right is 86 and going to the left is 87, 88 ,89 ,90 ,91
Answer:
y = -3/5x + c
Step-by-step explanation:
Re-arrange the initial equation so that the it becomes y =
To do this, you +3y on both sides to get 5x = 3y + 12
And then -12 on both sides to get 5x - 12 = 3y
Divide everything by 3 so you get 5/3x - 4 = y OR y = 5/3x - 4
The gradient of the initial equation is 5/3, to find the perpendicular line, you need the negative reciprocal of it, which is -3/5
Therefore your perpendicular line should be y = -3/5x + c
Because you didn't specify on what point they intersect, i can't find c for you.
Answer:
Step-by-step explanation:
Yes there should be an improvment. they should remember some of the answers to the puzzle they did the first time, so the second time, it would be faster and easier.
Answer:144 degrees
288 degrees
Step-by-step explanation:
Answer:
25, 21, 13, 9
Step-by-step explanation:
All you do here is plug in the X from the table to the X in the equation so,
y=29 - 4 x 1 = 25
y=29 - 4 x 2 = 21
y=29 - 4 x 4 = 13
y=29 - 4 x 5 = 9
