Find the slope of the line without graphing using the 2 points below.
malfutka [58]

Answer: m=-11

Step-by-step explanation:

To find the slope of the line, you want to use formula m=\frac{y_2-y_1}{x_2-x_1}. Since we are given two points, we can directly plug them in and solve.

m=\frac{-21-(-10)}{4-3} =\frac{-11}{1} =-11

Now, we know that the slope is -11.

How to do this question plz answer me step by step plzz plz ​

Answer:

New depth of the milk will be 4 cm.

Step-by-step explanation:

If the carton (shaded side) is standing vertically, milk in the box will acquire the dimensions of the box.

Length of the cuboid formed by the the milk = 8 cm

Width = 5 cm

Height = 12 cm

Volume of the cuboid formed by the milk in the carton = Length × width × height

V = 8 × 5 × 12

  = 480 cm³

If the carton is turned so that the carton stands on the shaded face,

Volume of the milk remains unchanged but the dimensions of the cuboid formed by the milk inside the carton will get changed.

Length = 15 cm

Width = 8 cm

Height = h cm

Then volume of the cuboid = Length × width × height

V = 15 × 8 × h

480 = 120h

h = \frac{480}{120}

h = 4 cm

Therefore, new depth of the milk will be 4 cm.

<h2>Writing an linear equation from a given scenario</h2>

Answer:

Choice B

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>

Scenario: A submarine dives 70 feet per minute.

We let f, be the position of the submarine from sea level as a function of t, the time (in minutes) since the submarine dived.

The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by 70 feet. So f(t) can be defined as -70t.

Now we can select two points for the graph. We can select points (1, f(1)) and (2, f(2)).

Evaluation of function:

f(1) = -70(1) \\ f(1) = -70

f(2) = -70(2) \\ f(2) = -140

Our points are (1, -70) and (2, -140)

Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.

So the correct graph is Choice B.
