16a. 21cm. bc when it has 10 grams it moves half of that to 5cm so divide 42 by 2 and you get 21cm
17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6
hope this helped :)
Answer:
m = 11
Step-by-step explanation:
-2(2 - 4m) = 6(m + 3)
Divide both sides by -2.
2 - 4m = -3(m + 3)
Distribute -3 on the left side.
2 - 4m = -3m - 9
Add 3m to both sides.
2 - m = -9
Subtract 2 from both sides.
-m = -11
Divide both sides by -1.
m = 11
8x-77 would be the answer to this
