75$ representing the 30 and the 100$ representing the 40
Answer:
y =
x - 1
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 = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2, 0) and (x₂, y₂ ) = (0, - 1) ← coordinates of intercepts
m =
=
= 
The y- intercept is - 1 ⇒ c = - 1
y =
x - 1
Answer:

Step-by-step explanation:
hello,
first of all we will study the quadratic expressions
we can write that, (the different answers provide good clues :-) )

and

so first of all as we cannot divide by 0 we need to take x different from 7, -12 and -30 and then we can write

hope this helps
Answer:
h= 17/2
Step-by-step explanation:
Y= -4x + 6 (-10, 46), (-1.11, 10.44),
y= -5x -4. (-10, 46)
whereas (-10, 46) is the solution for both equations, it is the correct choice
