Substituting 4 into the equation gets y = 9(4), which is equal to 36.
Answer:
<em>12 scoops of dog food are needed for 6 dogs,</em>
Step-by-step explanation:
<u>Proportions</u>
The number of scoops of dog foods and the number of dogs are proportional variables.
We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.
We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.
Thus, the constant of proportionality is 2.
For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.
12 scoops of dog food are needed for 6 dogs,
Slope of the equation is -9/2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
9x + 2y = 9
2y = -9x + 9
y = -9/2 x + 9/2
⇒ Slope, m = -9/2
Replacing 9 for the nth term of the sequence we get 9^2 + 1 = 82, Therefore the 9th term is = 82
