Determine the slope of the line that has the following coordinates: (5, 9)(11, - 3)

Answers

Answer 1
Answer:

Answer:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =(y_2 -y_1)/(x_2 -x_1)

And replacing we got:

m =(-3 -9)/(11-5)= -2

And the best answer for this case would be :

m=-2

Step-by-step explanation:

For this case we have the following two points given:

x_1 = 5, x_2 =11, y_1 =9, y_2 = -3

The slope can be founded with this formula:

m =(y_2 -y_1)/(x_2 -x_1)

And replacing we got:

m =(-3 -9)/(11-5)= -2

And the best answer for this case would be :

m=-2

Answers

Parallelogram is the answer,
rhombus, square, and trapezoid are all their own shapes, parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So basically a parallelogram is a shape with four sides.

A man flies a small airplane from Fargo to Bismarck, North Dakota --- a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only .9 hours. What is the plane's speed in still air, and how fast is the wind blowing?

Answers

Answer:

90 mi/h

Step-by-step explanation:

Calculate speed, distance, or time using the formula d = st, distance equals speed times time. The Speed Distance Time Calculator can solve for the unknown sdt value given two known values.

Time can be entered or solved for in units of seconds (s), minutes (min), hours (hr), or hours and minutes and seconds (hh:mm:ss).  

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

Plane speed in still air: 120mph

Wind speed: 30pmh

Speed of plane to Bismarck: 90mph

Speed of plane to Fargo: 150mph

Plot the zeos of this function: f(x) = (x-1)(x-7)​

Answers

Zeros of the given function f(x) = (x-1)(x-7)​ is (1, 0) and (7, 0).

Given function f(x) = (x - 1)(x - 7). Zeros of the function to be determined?

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

f(x) = (x - 1)(x - 7)​
for finding zero we must equal the function to zero.
f(x) = 0
(x - 1)(x - 7)​ = 0
Here equal to zero implies one of the parenthesis must be zero,
x - 1 = 0  or x - 7 =
x = 1 or x = 7
It shows x must be 1 or 7 so the function gives zero, i.e. coordinates (1, 0) and (7, 0) are zeros of the function f(x) = (x - 1)(x - 7)​.

Thus, zeros of the given function f(x) = (x-1)(x-7)​ is (1, 0) and (7, 0).

Answer:

(1,0) (7,0) so it’s 1 and 7

Step-by-step explanation:

You need to find the values of x that make the output equal to zero.

In a function like this, simple take the inverse of the number in each parentheses. For example if the number is -5, the zero is 5. And if it’s 5, the zero is -5.

This only works if the coefficient of x is 1.
