What is the slope of the line that passes through the points (-3, 5) and (1, 7)?

Mathematics

Answer: The slope of the line is \frac{1}{2}

Step-by-step explanation:

The slope of a line can be calculated with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

Then, given the points (-3, 5) and (1, 7), you can identify that:

y_2=5\\y_1=7\\\\x_2=-3\\x_1=1

Knowing these values you can substitute them into the formula for calculate the slope:

m=\frac{5-7}{-3-1}

Finally, evaluating, you get that the slope of that line is:

m=\frac{-2}{-4}\\\\m=\frac{1}{2}

The sum of five consective even numbers is less than 100.Find the maximum sum of these five numbers
Ludmilka [50]

100/5 = 20

would be the middle number so 18 +19+20+21+22 = 100

 since you want it to be less than 100 use 17 instead of 22

so you have 17 +18+19+20+21 = 95

95 is the maximum sum

During the first 50 minutes of flight, the Concorde climbs from ground level to an altitude of about 52,000 ft. What is the conc
horsena [70]

Let

x--------> the time in minutes

y-------> an altitude in feet

we know that

For x=0 min  y=0 ft

For x=50 min y=52,000 ft

so

the rate of change is equal to calculate the slope of the linear equation

\frac{52,000-0}{50-0}=\frac{52,000}{50}=1,040\frac{ft}{min}

Round to the nearest hundred-------->1,000\frac{ft}{min}

therefore

<u>the answer is</u>

1,000\frac{ft}{min}

G = {(5, 3), (2, 3), (6, 4)} Is G-1 a function and why?
galben [10]
To get G^-1 all we need to do is flip the points around Example for (5,3) make it (3,5)
Here are the points in inverse (3,5); (3,2); (4,6)
To tell if a group of point can be a function we need to 1st look at the x values.  If all the x values are different, then it is a function (the x's are not all different)
If there are x values that are the same, they MUST have the same y value.
look at the points (3,5) and (3,2) those have the same x but they go to different y values so it is not a function.

You can think about it like this.  Can you go to more than 1 place at the EXACT same time?  Obvious answer is no. Can you have multiple people go to the same room?  Sure that is possible.  Same with functions.  An x value can ONLY go to 1 y value, and many different x values can go to the same y value.
