Answer:
The length of the given line segment is cm
Step-by-step explanation:
Given end points are (-3,2) and (5,-1)
To find the length of a line segment with these given end points
By using the distance formula we can calculate the length of a line segment
Let and be the two end points (-3,2) and (5,-1) respectively
Therefore units
Therefore the length of a given line segment is cm
Let x represent the cost per gallon of gasoline.
Let y or f(x) represent the cost of x gallons of gasoline.
Given that the cost per gallon is $2.79,
The function would be
f(x) = 2.79x
The domain refers to all possible values of x that can fit into the function. Given that the truck holds a maximum of 28 gallons, the maximum value of x is 28. When the truck is empty, the minimum value of x is 0. Therefore, the domain is 0 to 28
The range refers to all possibel values of y or f(x) that can satisfy the function.
When x = 0, f(x) = 2.79 * 0 = 0
When x = 28, f(x) = 2.79 * 28 = 78.12
The range would be 0 to 78.12
Domain: 0 to 28
Range: 0 t0 78.12
Answer:
Jose is 54years Rachael is 38years
Step-by-step explanation:
Jose=x-12
Rachael=x-12/2
sum of their ages x-12+x-12/2=63
collect like terms
x=54years
Jose =54years
Rachael=38years
5.4 because the 9 bumps it to 5.35.
And the 5 bumps it to 5.4.
A + 5 > -7....subtract 5 from both sides
a > -7 - 5
a > - 12
