Answer:
y = -3x
Step-by-step explanation:
formula of slope is y=mx+b
you substitute the equation and you'll get
y = -3x
P C
3 39
4 48
5 57
6 66
9(3)=27+12=39=c
9(4)=36+12=48=c
57=9p+12
-12 -12
45=9p
divide by 9 both sides 45/9=5=p
c=9(6)+12
c=54+12
c=66
Answer:
we need the table!
Step-by-step explanation:
Answer:
66.67%
Step-by-step explanation:
Percent Error Formula =
| Approximate value - Exact value|/Exact value × 100%
| 2 - 3|/3 × 100%
1/3 × 100%
= 66.67%
The percent Error is 66.67 %
The situation that is a function is: C. The weight of a package and the cost of postage.
<h3>What is a Function?</h3>
A function can be described as a relation whereby there can only be one exact possible output value (dependent variable) for every input value (independent variable) in the relation. This means, no input value has two different output values. However, two different input values can have the same output value.
In a function, the output value is dependent on the input value.
For example, the cost of postage (output) is dependent on the weight of a package (input).
Therefore, the situation that is a function is: C. The weight of a package and the cost of postage.
