(a)

$\displaystyle y-12=-3(x-6)$

$\displaystyle y=-3x+30$

(b)

Scott took 27 minutes to deliver the packages

Decreased by 3 each day

Step-by-step explanation:

Equation Of The Line

We can define the equation of the line when we have two sets of data. They can be

One point and the slope Two points One point and the y-intercept The slope and the y-intercept

(a)

From the graph shown in the figure we can identify two points in the line:

$\displaystyle P(6,12)\ Q(3,21)$

We can now compute the slope of the line

$\displaystyle m=\frac{21-12}{3-6}$

$\displaystyle m=\frac{9}{-3}=-3$

With the slope and the point, we find the equation of the line

$\displaystyle y-12=-3(x-6)$

That was the slope-point form of the line. If we operate and reduce, we have

$\displaystyle y-12=-3x+18$

$\displaystyle y=-3x+30$

This is the slope-intercept form of the line

(b)

Using the model obtained in the part (a), we can predict or evaluate the values for any selected value of x. We are required specifically to find how long did it take Scott to deliver his packages. It can be computed setting x=1

$\displaystyle x=1$

$\displaystyle y=-3+30=27$

Scott took 27 minutes to deliver the packages

Finally, we are required to find how much dis his delivery time decrease by day. That is the exact meaning of the slope, the rate of change of y respect to x. Since we already computed the slope, we state

Scott decreased his delivery time by 3 each day

Answer from: Quest

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

$y< -2x+4$

$y< x+3$

$x< 3$

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

Which graph represents the following system of inequalities?

Answer from: Quest

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180

same as (2x + 16) + (x) = 180
