Answer:
1
Step-by-step explanation:
The zero of a liner function is where it crosses the x-axis
Answer:
It is 10.
Step-by-step explanation:
b=70 divided by 10 which is 7
You just need to put (x+1) wherever you see x at.
y=(x+1)^3 + 2(x+1)^2 -5(x+1) -6
y= x^3 +1 +2x^2+2-5x-5-6
y=x^3+2x^2-5x -10
Answer:
y =
x + 
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 ) = (- 2, 1) and (x₂, y₂ ) = (4, 6)
m =
=
, thus
y =
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 6 ), then
6 =
+ c ⇒ c = 6 -
=
= 
y =
x +
← equation of line
To find the m(slope) of our graph we can take two points from the graph, im going to use (0,2) and (1,8) the formula for slope is y2-y1/x2-x1
Plug the points in to get 8-2/1-0
The slope of this equation is 6.
For the y-intercept we just find where the line meets the y-axis and that is at 2.
The equation for this graph is y=6x+2
