Answer:
Step-by-step explanation:
Given:
The graphed point is (60,-20).
To find:
The ordered pair that would form a proportional relationship with the given point.
Solution:
If y is proportional to x, then



Where, k is the constant of proportionality.
For the given point,


For option (A),


For option (B),


For option (C),

.
The point (-30,10) gives the same value of the constant of proportionality. So, the point (-30,10) forms a proportional relationship with the given point.
Therefore, the correct option is C.
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.
Answer:
20s³ + 50s² + 32s + 6
Step-by-step explanation:
( 4s + 2 ) ( 5s² + 10s + 3)
use the distribution property:
20s³ + 40s² + 12s + 10s² + 20s + 6
combine like terms:
20s³ + 50s² + 32s + 6
therefore
the expand value = 20s³ + 50s² + 32s + 6
