Write the equation in slope-intercept form that has a x-intercept of 30 and a y-intercept of 15
Alexus [3.1K]

Answer:

\displaystyle y = -\frac{1}{2}\, x + 15.

Step-by-step explanation:

All non-horizontal line in the cartesian plane intersects the x-axis at a unique point. The x\!-coordinate of that point is the \! x-intercept of this line.

The x-intercept of the line in this question is 30. Thus, the x\!-coordinate of the intersection of this line and the \! x-axis would be 30\!.

Like all other points on the x-axis, the y\!-coordinate of that intersection would be 0. Therefore, the coordinates of that intersection would be (30,\, 0).

Similarly, the y-intercept of a non-vertical line is the y\!-coordinate of the point where that line intersects the y\!\!-axis.

The slope-intercept form of a line is in the form y = m\, x + b, where m is the slope of the line and b is the y-intercept of this line. Both m\! and b\! are constants.

It is given that the y-intercept of the line in this question is 15. Therefore, b = 15. The slope-intercept equation of this line would be y = m\, x + 15 for some slope m to be found.

All points (x,\, y) on this line should satisfy the equation y = m\, x + 15 of this line. The x-intercept of this line, (30,\, 0), is a point on this line. Thus, the equation y = m\, x + 15\! should hold for x = 30 and y = 0. Substitute these two values into the equation and solve for the slope m:

0 = 30\, m + 15.

\displaystyle m = -\frac{1}{2}.

Therefore, the slope-intercept equation of this line would be:

\displaystyle y = -\frac{1}{2}\, x + 15.

A postal service requires that any box sent by priority mail have length plus girth​ (distance around) totaling no more than 104
Vaselesa [24]

Answer:

The length is no more than 56 inches.

The volume of the box is 8064 cubic inches.

Step-by-step explanation:

Given : A postal service requires that any box sent by priority mail have length plus girth​ (distance around) totaling no more than 104 in. One volume that meets this condition is contained by a box with a square end 12 in. on each side.

To find : What is the length of the​ box? What is the​ volume?

Solution :

A square end 12 inch on each side.

Then the girth of the box is given by,

P=4\times s

P=4\times 12

P=48

The girth of the box is 48 inches.

A postal service requires that any box sent by priority mail have length plus girth​ (distance around) totaling no more than 104 in.

So, L+48\leq 104

L\leq 56

The length is no more than 56 inches.

The maximum volume of such a box would be,

V=L\times B

B = area of the base (or end) of the box,

So, B=12^2=144

The volume is

V=56\times 144

V=8064\ in^3

Therefore, The volume of the box is 8064 cubic inches.

As of 2016, New York City has a population of 8.55 million and a land area of 300 square miles. Manhattan is a section of New Yo
sineoko [7]

Answer: 42804 people per square mile

Step-by-step explanation:

As we know Population density = \dfrac{Number\ of\ people}{Area}

Given, population of New York City =  8.55 million

Area of New York City  = 300 square miles

Then, population density of New York City = \dfrac{8.55\text{ million}}{300\text{ square miles}}

=\dfrac{8550000}{300\text{ square miles}}=28500\text{ people per square mile}   [1 million = 1,000,000]

Population of Manhattan =  1.64 million = 1640000

Area of Manhattan  = 23 square miles

population density of Manhattan = \dfrac{1640000}{23}\approx71304\text{ people per square mile}

Difference = 71304 - 28500 =42804

Hence, population density of Manhattan is 42804 people per square mile greater than that of New York City.
