Quadratic functions can be written in three forms. The parameters and are the roots of the function (the x-intercepts of the graph ). Converting a quadratic function to factored form is called factoring. ... The parameter is the y-intercept, while the parameter is the slope of the tangent at 0.
Answer:
its 40,000
Step-by-step explanation:
Yes, you can do it using substitution. However, elimination would be better because you could just add the two equations and have y cancelled out immediately.
Answer:
the answer I believe will be 25.16
Answer:
y = x + 30
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 30) and (x₂, y₂ ) = (70, 40) ← 2 points on the line
m = = =
The line crosses the y- axis at (0, 30) ⇒ c = 30
y = x + 30 ← equation of line
