Find the slope of the line passing through the points (3, 4) and (8, -3).

Answers

Answer:

        [tex]\bold{m=-1\dfrac25}[/tex]

Step-by-step explanation:

The slope of the line passing through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(3, 4)   ⇒   x₁ = 3,  y₁ = 4

(8, -3)   ⇒     x₂ = 8,  y₂ = -3

So, the slope:

                     [tex]m=\dfrac{-3-4}{8-3}=\dfrac{-7}{5}=-1\dfrac25[/tex]

Answers

Answer:

The correct answers are;

4 * 3 1/4

3 1/4 + 3 1/4 + 3 1/4 + 3 1/4

13/4 + 13/4 + 13/4 + 13/4

Step-by-step explanation:

Given 4 ropes each 3 1/4 feet long

1 rope = 3 1/4 feet long

4 ropes = x

cross multiply

1 * x = 4 * 3 1/4

x = 4 * 3 1/4

Since 3 1/4 is in 4 places, the total length can also be expressed as;

3 1/4 + 3 1/4 + 3 1/4 + 3 1/4

We can also rewrite as an improper fraction

Since 3 1/4 = 13/4

Total length = 13/4 + 13/4 + 13/4 + 13/4

See below

Step-by-step explanation:

Given the data set of 15 where:

Mean = 7Median = 6Mode = 5The minimum is 1 and the maximum is 10

As per given we conclude

The set will have 7 numbers before 6 and 7 numbers afterSum of 15 numbers is 15*7 = 105The most used number is 5

a) Possible set is:

1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10

b) Add number 20, the set will be:

1, 5, 5, 5, 5, 5, 5, 6, 9, 9, 10, 10, 10, 10, 10, 20

The mean is different as we have now more numbers with different sum:

(105 + 20)/(15 + 1) = 125/16 = 7.8125

The median is different now and moves to the right as 20 added to the far right:

(6 + 9)/2 = 7.5

The mode stays same as still most used number is 5:

Write in equation in slope form of the line shown

Answers

Answer:

y=2x-5

Step-by-step explanation:

Slope intercept form is y=mx+b, with m being the slope and b being the y-intercept.

Slope is found through (y2-y1)/(x2-x1) and when the values are plugged in you get (-3-1)/(1-3) which equals -4/-2 or 2.

y=2x+b

Since b is the y-intercept, you plug in the value of the point where the line crosses over the y axis. In this case, that value is -5, so you get y=2x-5.

Perimeter is the length of the border. The best way to find it here is to split the figure up into a semicircle and a trapezoid.

The radius of the semicircle is 9 in. so its perimeter is 2pir/2 = 9pi in.

The perimeter of the trapezoid can be found by adding the lengths of all sides. The bottom side is 2 times the radius of the semicircle, 18 inches. Add this to the other lengths: 5 in, 12 in, 5 in.

The total perimeter is then 40 + 9pi.

what is the answer to 6a + 6c =126

Answers

Answer:

Step-by-step explanation:

You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.

6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23.  Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.
