If you are talking about on Brainly.com it is like this.
To write half write 1/2 (1 forward slash 2)
X = 60°
Because the square in the corner tells you that it is 90° (right angle)
So your equation to solve for x would be...
x + 30 = 90
Now you need to isolate the x.
Subtract both sides by 30.
x + 0 = 90 - 30
x = 60
Answer:
750.64
Step-by-step explanation:
A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4
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.
