What is an
equation of the line that passes through the points (-1,-4) and
(-2,-8)?

Answers

Answer 1

Answer:

y = 4x

Step-by-step explanation:

To start, we need to find the slope:

m = y₁ - y₂ / x₁ - x₂

Substitute the numbers and solve for the slope:

m = -4 - (-8) / -1 - (-2)

m = -4 + 8 / -1 + 2

m = 4 / 1

m = 4

Now we know that the slope is 4.

Next, we need to use point-slope form:

y - y₁ = m(x - x₁)

Once more, substitute the numbers:

y - (-4) = 4(x - (-1))

y + 4 = 4(x + 1)

y + 4 = 4x + 4

y = 4x

Therefore, the equation of the line is y = 4x.

Answers

Answer:

Option "B" is correct answer

Step-by-step explanation:

Given:

Wal-Mart Stores, Inc = 677,500

General Motors Corp = 646,200

Pepsi Co, Inc. = 485,100

Ford Motor = 372,900

Sears Roebuck & Company = 336,100

Find:

Chart

Computation:

Total = 677,500 + 646,200 + 485,100 + 372,900 + 336,100

Total = 2,517,800

Percent Wal-Mart Stores, Inc = 677,500 / 2,517,800 = 26.90 %

Percent General Motors Corp = 646,200 / 2,517,800 = 25.66 %

Percent Pepsi Co, Inc. = 485,100 / 2,517,800 = 19.26 %

Percent Ford Motor = 372,900 / 2,517,800 = 14.81 %

Percent Sears Roebuck & Company = 336,100 / 2,517,800 = 13.34 %

Select the graph that correctly represents ƒ(x) = –2(x + 4)2 – 1.

Answers

The graph that correctly represents f(x) = –2(x + 4)² is graph (B).

What is a graph?A graph is a diagram that depicts the connections between two or more objects. A pie chart is a type of graph. In discrete mathematics, a graph is made up of vertices—a collection of points—and edges—the lines connecting those vertices. In addition to connected and disconnected graphs, weighted graphs, bipartite graphs, directed and undirected graphs, and simple graphs, there are many other types of graphs.

So, graph of: f(x) = –2(x + 4)²

Then,

f(x) = -2(x + 4)² f(x) = (-2x - 8)²

Now, plot (-2x - 8)² on the graph.

(Refer to the graph attached below)

Therefore, the graph that correctly represents f(x) = –2(x + 4)² is graph (B).

What is the equation of y = x 3 y = x 3 with the given transformations? vertical stretch by a factor of 3, horizontal shift 4 units to the right, vertical shift 3 units down

Answers

Answer and Step-by-step explanation: In math, a graph, function or equation can be alterated - by shifting, reflecting, stretching or compressing - without losing its original shape. For example, a quadratic function maintains its parabolic shape when shifted.

When an equation is transformed vertically, it means its y-axis is changed. When it is horizontally, its x-axis is modified.

For equation [tex]y=x^{3}[/tex]:

Vertical stretch by a factor of 3:

This means the exponential equation will be multiplied by a constant, in this case 3. Then, the new equation is

[tex]y=3x^{3}[/tex]

Horizontal shift 4 units to the right:

When an equation is shifted, it's added a constant to it. As it is horizontal, it means it is added to the x and because it is to the right, it is a plus symbol:

[tex]y=x^{3+4}[/tex]

Vertical shift 3 units down:

Vertical shift means the equation is 3 units "below" the original equation, so:

[tex]y=x^{3}-3[/tex]

What constant acceleration is required to increase the speed of a car from 23 mi/h to 51 mi/h in 5 seconds? (Round your answer to two decimal places.)

Answers

Answer:

337.35 mi/h^2

Step-by-step explanation:

Given the equation;

v= u +at

v= final velocity = 51 mi/h

u= initial velocity = 23 mi/h

t = time = 5 mins or 0.083 hours

a = acceleration, the unknown

51 = 23 + 0.083a

51 - 23 = 0.083a

a= 51 - 23/0.083

a= 337.35 mi/h^2

3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.

In accordance with the law, if r became smaller, and V stayed the same, the current would increase. The increases would be inversely proportional to the resistance, if the resistance was halved, the current would double.

4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. The resistance of a conductor is the ratio of the voltage
