Answer:
The ratio that compares the diameter of the first circle to the diameter of the second circle is
Step-by-step explanation:
Circumference of a circle:
The circumference of a circle of diameter d is given by:
In which d is the diameter.
One circle has a circumference half as large as that of a second circle.
We have that:
So
Simplifying by
The ratio that compares the diameter of the first circle to the diameter of the second circle is
The constant of proportionality, o slope, is the coefficient multiplying in the equation. The y-intercept is the constant term added at the end, with no variable:
Answer:The solution to a system of linear equations is the point at which the lines representing the linear equations intersect. Two lines in the x y xy xy -plane can intersect once, never intersect, or completely overlap.
A system of linear equations is usually a set of two linear equations with two variables. x + y = 5 x+y=5 x+y=5x, plus, y, equals, 5 and 2 x − y = 1 2x-y=1 2x−y=12, x, minus, y, equals, 1 are both linear equations with two variables. When considered together, they form a system of linear equations.
a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. For example, in the quadratic polynomial the 3 is a constant term.
