Answer:
Step-by-step explanation:
We have to find the domain and range of each function.
a.
It is a linear function because the degree of function is 1.Linear function is defined for all real values of x.
Therefore, the domain of given function=R
When we substitute real values in the given function then we get again real values.
Therefore, range of f=R
b.
It is a linear function .
Domain=R
Range=R
c.
C(x)=Number of calories in a sandwich containing x grams of fat.
x=Mass of fat
Mass is always a natural number.
Domain of C=N
Substitute x=1
C(1)=9(1)+130=139
C(2)=9(2)+130=18+130=148
Range of C={139,148,157,...}
d.
B(x)=Number of bacteria
x=Time in hours
Number of bacteria is a natural number and time is always a whole number.
Domain=W
Substitute x=0
Range of B={100,200,200,800,...}
Separate the shape into a triangle and a rectangle.
Find the area of the rectangle 7ft x 8ft = 56ft^2
find the height of your triangle 6ft+8ft=14ft
find the area of the triangle 1/2 (18ft x 14ft) = 126ft^2
Add the two areas together —> 56 + 126 = 182ft^2
None of them have perpendicular lines except for the blue one if I am seeing right.
Answer:
30 + s = 2s - 10
Step-by-step explanation:
Have a good day!
This is the answer because a number more means +
and decreased means -
times is when a number is next to another number <em>Example: </em>{1(2) = 2}/ 1 x 2 = 2
