Step-by-step explanation:
let eqn be y = mx + b.
m = (5 - (-16))/(1 - 8) = -3
sub (1, 5):
5 = -3(1) + b
b = 8
therefore it's y = -3x + 8

Answer:
He has 60 paper clips before giving some away.
Step-by-step explanation:
Before : 5x : 3x
After: 5x - 12 = 3x + 12
5x - 12 = 3x + 12
First, we need to take away the smallest value of x from the largest.
-3x
2x - 12 = 12
Then, we need to add +12 to get rid of -12 on the lefthand side.
2x = 24
Divide by 2 to get x on its own.
x = 12
Bert had 5x so we need to multiply x (what we found as 12) by 5. 12 x 5 = 60. Bert had 60 paper clips before he gave some away.
We can prove this answer as correct, too.
5 x 12 = 60
3 x 12 = 36
60 - 12 = 36 + 12
48 = 48
Hope this helps, have a good day. :D
Answer:
You are solving for the incline of the slope of the mountain to find out what kind of equipment you bring. You find that part of the mountain has a slope of 1, which meant you had to bring pickaxes, ropes, and other vertical climbing gears. On the other side, you see that the slope is only 1/3. This is much more easier to climb, and seems to be the better option of the two.

{ 3 x - 2 y = 30 * ( 2 )
2 x + 3y = - 19 * ( -3 )
↓
6 x - 4 y = 60
- 6x - 9 y = 57
______________
-13 y = 117
y = 117 / - 13
y = - 9
For x :
3 x - 2y = 30
3 x - 2 ( -9) = 30
3 x + 18 = 30
3 x = 30 - 18
3 x = 12
x = 12 / 3
x = 4
x = 4 and y = -9
hope this helps!
Property of Zero because anything multiplied by 0 equals 0. If this is right could I possibly have brainliest? Hope this helped!! :)
