Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
The best statement that describes the associations between variable X and variable Y is the first option, "no association."
Answer:
Step-by-step explanation:
Given:
The equations given are:
Now, a linear function is of the form:
Where, 'm' and 'b' are real numbers and 
Equation 1:
Simplifying using distributive property, we get:
The above equation is of the form . So, it represents a linear function.
Equation 2: 
Here, both sides of the equation has same variable 'X'. So, it will form an equation of 1 variable. So, it's not a linear function.
Equation 3: 
Simplifying the above equation. This gives,
This is not of the form of the linear function. So, it is also not a linear function.
Equation 4: 
Simplifying the above equation. This gives,
This is not of the form of the linear function. So, it is also not a linear function.
Answer:
$24.00
Step-by-step explanation:
x = per month
y = per song
t = total
Equation:
t = 14x + 0.5y
t = 14(1) + 0.5(20)
t = 14 + 10
t = 24
