Answer:
sorry dont know just did this to get 5 pionts :)
Step-by-step explanation:
70 / 35 = 2
So the 70 pound dog weights double the weight of the 35 pound dog, so he will eat twice as much.
2 x 2.5 = 5 cups
Meaning he will eat 5 cups of dry dog food a day.
By the same logic a 140 pound dog would have to eat twice what a 70 pound dog eats, that is 10 cups of dry dog food a day, so 7 1/2 cups are not enough.
Challenge: per pound a dog eats more than a cat. Since you know a 140 pound dog eats 10 cups, you can dive 140 by 10, to find out that each cup feeds 14 pounds, so half a cup would be the amount of food to feed a 7 pound dog, meaning that a dog weighing 1 pound less than a 8 pound cat would need the same amount of food, so it eats more than a cat.
Answer is C
Hope that helps
Answer:
Slope is -3/7. Y intercept is 250/7.
Step-by-step explanation:
Since they asking for the slope and y intercept, let put it in slope intercept form.

where m is the slope and b is the y intercept.
The equation given is in standard form so we will convert it to slope intercept.




The slope is -3/7
The y intercept is 250/7
