Answer:
m=2
Step-by-step explanation:
We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.
Therefore, substituting the values of x=3 and y=-1 in the given line, we have,
⇒
⇒
⇒
⇒
⇒
Hence,the value of m will be equal to two.
Answer : The average rate of change between 1 year and 4 years of age is 7.33 lbs per year.
Step-by-step explanation :
As we know that the average rate of change between two input values is the total change of the output values divided by the change in the input values.
From the table, we conclude that:
The weight of 1 year of age = 20 lbs
The weight of 4 years of age = 42 lbs
Now we have to determine the average rate of change between 1 year and 4 years of age.
The input (years) has changed by = 4 years - 1 year = 3 years
The output has changed by = 42 lbs - 20 lbs = 22 lbs
Average rate of change = Output ÷ Input
Average rate of change =
Average rate of change = 7.33 lbs per year
Therefore, the average rate of change between 1 year and 4 years of age is 7.33 lbs per year.
Answer:
.
Step-by-step explanation:
Note: The number is not in proper form. Consider the given number is .
If a number is added to another number and we get zero, then the added number is known as additive inverse.
Let a be a number, then
So, -a is the additive inverse of a. It means, additive inverse is the same number with opposite sign.
Consider the given number is .
Therefore, the additive inverse of is
.
