Answer:
16
Step-by-step explanation:
2^4 is the same thing as 2*2*2*2*2. 2 times 2 is 4, times 2 is 8, times 2 again is 16.
1- y= x/2 + 2
2- y= 3x +1
3- y= x/2 - 2
4- y= 3x - 1
Answer:
A) 
- Linear
B) 
- Linear
C) 
- Nonlinear
Step-by-step explanation:
To determine whether a function is linear or nonlinear.
The function of a straight line is given as :
where 
represents slope of line and 
represents the y-intercept.
Any function that can be represented as a function of straight line is called a linear function otherwise it is nonlinear.
We will check the equations given for linear or nonlinear.
A)
The function is in the form and hence it is a linear function with slope 
and y-intercept 
.
B)
The function is in the form and hence it is a linear function with slope 
and y-intercept 
.
C)
On solving for 
Dividing both sides by 
This function cannot be represented in the form , hence it is a nonlinear function.
Answer:
x=81
y=99
z= 129
Step-by-step explanation:
the 3 angles of a triangle add to 180 degrees
51 + 48 + x = 180
99 + x = 180
subtract 99 from each side
99 + x -99 = 180 -99
x = 81
x+y = 180 they make a straight line
81+ y = 180
subtract 81 from each side
y = 180-81
y = 99
z+ 51 = 180 they make a straight line
subtract 51 from each side
z+51-51 = 180 -51
z = 129
Answer:
the answer is 3xy
Step-by-step explanation:
2x can be combined with -5x and x because they have the same variables, but 3xy has the variable xy so it cannot be combined with the others
