Given u/7 - 1 = 7 and plugging in values for u,
For u = 28; 28/7 - 1 = 4 - 1 = 3; No
For u = -49; -49/7 - 1 = -7 - 1 = -8; No
For u = 42; 42/7 - 1 = 6 - 1 = 5; No
For u = 0; 0/7 - 1 = -1; No
Another way to find out which value would be a solution to u/7 - 1 = 7 is to solve for u.
u/7 - 1 = 7
u/7 = 7 + 1
u/7 = 8
u = 8*7
u = 56
The only solution to this equation is when u = 56.
Y = 162 - x would be the equation for the lower data set.
39 hours, 13 minutes and 50 seconds
To solve for y you have to simplify both sides of the equation, then isolating the variable which equals to...
y = -4x/3 + 4
Next, you have to move all terms that don't contain y to the right side and solve.
y = 10 + 2x/3
____
Now we solve the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-3,8)
Equation Form: x = -3, y = 8
____
Leaving it to be the only choice which is 'D.) 8', I hope this helps, as always. I wish you the best of luck and I hope you have a nice day..
