The two partial products would be 990 *30 and 990 *7
You can also break it up into 900*37 and 90*37
Answer:
1/2
Step-by-step explanation:
Answer:
Shelter A
Step-by-step explanation:
The reason it's shelter a is because the dog that weighs the most in shelter a is 30 lbs and the dog that weighs the most in shelter b is only 28 lbs. So shelter a is your answer.
You can tell if it has direct variation by finding the slope and inserting it and the coordinates into point slope form.
You can find the slope by putting both sets of coordinates into the equation
y - y / x -x , where the first y and x are from one set of coordinates, and the next two are from the other set.
(7.5 - 3) / (11.25 - 4.5)
4.5 / 6.75
The slope is 2/3
Next, input the slope and the origin (0,0) into point-slope form.
y - y = m (x - x) Substitute.
y - 3 = 2/3 (x - 4.5) Distributive Property.
y - 3 = 2/3x - 8/15 Add 3 to both sides.
y = 2/3x + 37/15 Simplify.
y = 2/3x + 2 2/15
So you know that the line does not go through origin, because its y-intercept is 2 2/15.
For the second one do the same things.
y -y / x - x
(3 - 1.5) / (12 - 8)
1.5 / 4
3/8
y - y = m ( x - x )
y - 3 = 3/8 (x - 12)
y - 3 = 3/8x - 24/8
y = 3/8x - 0
y = 3/8x
So the second one goes through the origin because its y-intercept is 0. The answer is Table 2 has direct variation.
