Answer:
$28.70
Step-by-step explanation:
Let b represent the amount Belle has. Then the amount Abe has is b+9, and the amount Cathy has is 3(b+9). The total of their amounts is ...
(b+9) +b +3(b+9) = 179.50
5b +36 = 179.50
5b = 143.50
b = 28.70
Belle has $28.70.
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
Answer:
the height when the plant was planted
Step-by-step explanation:
The "y-intercept" is the value of the dependent variable (height) when the independent variable (days) has a value of zero.
The table description tells you the table represents height since the plant was planted. If days since the plant was planted are zero, the height at that time is the height when the plant was planted.
