She can only make 2 trail mixes
Answer: 17
Step-by-step explanation:
We can tell that for every 2 changes in X there is 8 points lost in y
meaning that if we do 8 /2 we get 4
Every 1 change in x there is 4 points of change in Y
so if (3,5) Then (0,17)
17 - 5 = 12 And 3-0 = 3 So for 3 points of change for Xthere were 12 points of change for Y so this is right
Answer:
see explanation
Step-by-step explanation:
(a)
y =
- bx
substitute y = 6 , x = 1 into the equation
6 = a - b → (1)
substitute y = 0 , x = 2 into the equation
0 =
- 2b ( multiply through by 2 to clear the fraction )
0 = a - 4b → (2)
multiply (1) by - 4
- 24 = - 4a + 4b → (3)
add (2) and (3) term by term to eliminate b
- 24 = - 3a + 0
- 24 = - 3a ( divide both sides by - 3 )
8 = a
substitute a = 8 into (1) and solve for b
6 = 8 - b ( subtract 8 from both sides )
- 2 = - b ( multiply both sides by - 1 )
2 = b
Then a = 8 and b = 2
(b)
when x = 4
y =
- 2(2) = 2 - 4 = - 2
