*the function drawn by Jamal is the attachment below

Answer:

A) It is linear because it has a constant rate of change.

Step-by-step explanation:

When you plot all the coordinates of a linear function on a graph, the line that passes through all the points plotted is typically a straight line. There would be absence of any curve or bends. All you'd have is a straight line.

Consequent on this, a straight line indicates that the rate of change remains the same along the line slope.

If you pick any two points on the line and calculate the rate of change, it would give you the same rate of change you'd get when you calculate the rate of change of another two points on the line.

A straight line indicates a constant rate of change. Therefore, the function drawn by Jamal is a linear function because it has a constant rate of change.

For the expression: (− 1/x )× 1−x/1+x × x/x^2−1 Simplify the expression.

Contact [7]

Answer:

The simplified answer is $1/(x+1)^{2}$

Step-by-step explanation:

For the given expression: (− 1/x )× 1−x/1+x × x/x^2−1

we need to simplify it

$x^{2} -1$ = (x+1)×(x-1)

eliminating x and x-1 from the given equation we get

$1/(x+1)^{2}$

The value of x can't be zero

As we can't divide zero by zero

The value of x can't be one

As we can't divide zero by zero

The simplified answer is $1/(x+1)^{2}$

Can someone please help

It may be convenient here to write the equation of the line as

... ∆y(x -x0) -∆x(y -y0) = 0

where (x0, y0) is a point on the line, and (∆x, ∆y) is the difference between two points on the line.

Using the first two points, we have

... (∆x, ∆y) = (-9, 10) - (-15, 5) = (6, 5)

So, the equation of the line is

... 5(x +9) -6(y -10) = 0 . . . . . . using the point (x0, y0) = (-9, 10)

... 5x -6y = -105 . . . . . . . . . . . simplify to standard form

Now, dividing by the constant on the right, we can put this into intercept form

... x/(-21) +y/(17.5) = 1

This tells us the y-intercept is (0, 17.5) and the x-intercept is (-21, 0).

You can work directly with the values in the table. The y-value increases by 5 from one line to another, while the x-value increases by 6. Thus, to make the y-value decrease by 5 from the first point, we need to decrease that point's x-value by 6 to -21. That is, the x-intercept is (-21, 0).

Similarly, the x-value need to increase by only 3 from the last point. That amounts to half of the usual increase of 6. Thus the y-intercept will be the last point plus have the usual y-increase of 5, or 15+2.5 = 17.5. That is, the y-intercept is (0, 17.5).

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more

Vanyuwa [196]

The described situation represents a normal distribution.
For a normally distributed distribution, P(X < x) = P(z < (x - mean) / standard deviation))
P(x > 100) = 1 - P(z =< 100) = 1 - P(z < (100 - 80) / 12.12) = 1 - P(z < 1.6502) = 1 - 0.95055 = 0.04945 = 4.9%

Therefore, the required percentage of the customers expected to get free gifts is 4.9%.
