Answer:
y = 5.5x - 17
Step-by-step explanation:
(4,5)(2,-6)
- M = ∆y/∆x
- -6-5/2-4
- -11/-2 this is the gradient
- chose any of the point then introduce another point
- (4,5) (x,y) the gradient is -11/-2
- M =∆y/∆x
- y-5/x-4 = -11/-2
- -2(y-5) = -11 ( x -4)
- -2Y + 10 = -11x + 44
- -2Y = -11x + 44 -10
- -2Y = -11x + 34
- divide the while equation by -2
- y = 5.5x + - 17
- y= 5.5x - 17
Answer15 y-int. (sety=0) 5%-15 (set x=0) x=3. 13,0).
Step-by-step explanation:
1,076 (the original thickness) - 22.7 meters (loss per year) * 7 (lost 22.7 meters per year for seven years, so multiply the loss per year by the amount of years) = 917.1 (the size after 7 years)
A.K.A 1,076 - 22.7 * 7 = 917.1
Answer:
5
Step-by-step explanation:
2x + 1 = 3x - 4
-2x -2x
--------------------
1 = x - 4
+4 +4
----------------
5 = x
The answer is 5.
Hope this helped.
