Answer: y = 1/2x - 7
<u>Data</u>
Point = (-4, -9)
slope = m = 1/2
<u>Process</u>
To solve this problem, use the formula slope- y-coordinate, substitute the values and simplify.
<u>Equation</u>
y - y1 = m (x - x1)
x1 = -4
y1 = -9
<u>Substitution</u>
y + 9 = 1/2 (x + 4)
<u>Simplification</u>
y + 9 = 1/2x + 4/2
y = 1/2x + 2 - 9
<u>Answer</u>
y = 1/2x - 7
2x , x represents the number of day in winch for example if it was the 5th day you would multiply 2 x 5 do you get it or need more explaining
Step-by-step explanation:
hihi, so this is a classic interest rate problem. It's not too bad if you know your properties of e and ln. After establishing the base equation you can divide by 100 then take the natural log of both sides to "get rid" of the e and finally end it by dividing by 10 to isolate r.
