Let the sister be x years old.
Then Jessica is x + 5 years old.
Their ages add to 47.
x + x + 5 = 47
2x + 5 = 47
2x = 42
x = 21
x + 5 = 26
Jessica is 26, and her sister is 21.

Answer:
y = -5/3x - 3
Assuming this is a linear function
Step-by-step explanation:
1. Use (y2-y1)/(x2-x1) to find the slope of the equation, assuming it is a linear function.
(-3-2)/(0+3) = -5/3 <--- slope
2. The y-intercept is going to be the (0, -3) point, since the point is directly on the y-axis.
3. Put both of those values into the new equation
y = -5/3x - 3

Answer: - 2.4x^2 - 1.5x - 11.4
Step-by-step explanation:
- 4.1x^2 + 0.9x - 9.81.7x^2 - 2.4x - 1.6 = - 2.4x^2 - 1.5x - 11.4
