Answer:
Linear :
Non linear :
Step-by-step explanation:
Given:
The equations given are:
Now, a linear equation is of the form:
Where, 'm' and 'b' are real numbers and 'm' not equal to 0.
The highest exponent of 'x' in a linear equation is always 'one'.
Therefore, if the exponent of 'x' in an equation is anything other than 'one', then the equation is a nonlinear equation.
The equation can be rewritten as:
The above equation is of the form of a linear equation with . So, this represents a linear equation.
The other two equations have exponent 3 for 'x' which is not '1'. So, these equations are nonlinear equations.
Answer: The 3 is the numerator.
The top number is always the numerator.
The standard form of the equation of circle is:
(x – h)^2 + (y – k) ^2 = r^2
Where the center being at the point (h, k) and the radius
being r
Substituting the values to the equation:
<span>(-15 - (-7)) ^2 + (y – (-1)) ^2 = 13^2 </span>
64 + (y +1) ^2 = 169
(y +1) ^2 = 105
y + 1 = 10.247
<span>y = 9.247</span>
Answer: there are three feet in a yard, so first multiply 880 times 3 to get 2640 feet
Then multiply by the number of feet per mile. (5,280)
3 times 880 = 2,640
2,640 feet times 1 mile/5,280 feet.
Step-by-step explanation:
Answer:
$50
Step-by-step explanation:
x is distance and y is cost because the cost is dependent on the distance which makes the distance the independent variable. you can always use y=mx+b for these problems!!
