Answer: answer is 2
Step-by-step explanation:
Answer: I'm pretty sure its a or the first one ^w^
Step-by-step explanation:
Slope intercept form will help you find the function of the line :) [ y = mx + b ]
at time = 0 (y-intercept) the pool is 72in deep
the pool loses 2 inches of water every 1 hour. or -2/1
so your equation is y = -2x + 72
Good Luck!
1)
Ordered pairs: { (-2,5), (-1,2), (0,1), (2,5)}
Domain: these are the x-coordinates = {-2, -1, 0, 2}
Range: these are the y-coordinates = { 1, 2, 5}
2) <span>{(5, –2), (2, –1), (1, 0), (2, 1), (5, 2)};
domain: {–2, –1, 0, 1, 2}; wrong it is {1, 2, 5}
range: {1, 2, 5}; wrong it is {-2, -1 , 0, 1, 2}
Now you can do the others.
