Step-by-step explanation:
Given : Previous baby's weight = 18 pounds
New baby's weight = 24 pounds.
Increase in weight = New weight -Previews weight
=24 pounds - 18 pounds =6 pounds
Percentage increase in baby's weight =![=\dfrac{\text{Increase in baby's weight}}{\text{previous weight}}\times100](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Ctext%7BIncrease%20in%20baby%27s%20weight%7D%7D%7B%5Ctext%7Bprevious%20weight%7D%7D%5Ctimes100)
![\\\\=\dfrac{6}{24}\times100=25\%](https://tex.z-dn.net/?f=%5C%5C%5C%5C%3D%5Cdfrac%7B6%7D%7B24%7D%5Ctimes100%3D25%5C%25)
Hence, the percentage increase in baby's weight = 25%
Answer:
x = -1/2 and -2
Step-by-step explanation:
Solve for <em>x</em>: Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Using the quadratic formula: Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
19. 5x - 5 = 3x -9
2x = -4
x = -2
19. Answer is A
Shortcut: you notice that the curve passes through (1,0)
Only log function passes this point.
