The sum of two numbers is sixteen. One number is forty less than three times the other. Find the numbers.

y = 14  x = 2

Step-by-step explanation:

what we know:

x + y = 16

x = 3y - 40

3y - 40 + y = 16

4y - 40 = 16

add 40 to both sides

4y = 56

y = 14

x = 3(14) - 40

x = 42 - 40

x = 2

in 4 days he will run   12/14

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.
