The x-intercept of a line is when the y coordinate is equal to 0. So, the x-intercept would be (0,-7).
The y-intercept of a line is when the x coordinate is equal to 0. So the y-intercept would be (-5,0).
To find the equation of a line, you need the slope and the y-intercept.
We already know the y intercept is -5. The equation for a line is:
Y=mx+b
m stands for slope
b stands for the y intercept.
To find the slope, use the equation-
y1-y2
--------
x1-x2
Another way to say that is the change in y over the change in x.
Plug in the the 2 coordinate points you know, which are (-7,0) and (0,-5).
0+5
-------,
-7-0
5/-7.
The slope is 5/-7
The Y intercept is -5
The equation of the line is y= 5/-7x -5
The coordinate point for the x intercept is (-7,0)
The coordinate point for the y intercept is (0,-5)
Answer:
42666 cases
Step-by-step explanation:
P = (Marginal Loss)/ (Marginal Loss + Marginal Profit)
P = (35)/(35+15) = 0.7
Considering a normal distribution we can find the corresponding z value by P = 0.7 (which represented the shaded area under the curve)
z = 0.5244
z = (X - Mean Sales)/Standard Deviation
-0.5244 = (X - 45000)/4450
X = 42666.42 ≅ 42666

Answer: A pair of inverse operations is defined as two operations that will be performed on a number or
variable, that always results in the original number or variable. Another way to think of this is
that the two inverse operations “undo” each other. For example, addition and subtraction are
inverse operations since we can say
x x 2 2 . If we start with x, then add 2 and subtract 2,
we are left with the original starting variable x.
There are several inverse operations you should be familiar with: addition and subtraction,
multiplication and division, squares and square roots (for positive numbers), as well as cubes and
cube roots. The following examples summarize how to undo these operations using their
inverses
