find the slope, m and y-intercept of the line y=4x

Answers

Answer:

The answer is m=4

Step-by-step explanation:

Although it may not look like it this equation is in slope-intercept form. The slope-intercept form of a linear equation is:  

y = m x + b

Where m  is the slope and  b  is the y-intercept value.

Therefore:

The slope is:  

m = 4

The  y -intercept is:  b = 0  or  ( 0 , 0 )

The slope of the line is 4 and the y-intercept is 0.

We are given that;

Line equation y=4x

Now,

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

To find the slope and y-intercept of the line y = 4x, we can compare it with the slope-intercept form and identify the values of m and b.

In this case, m = 4 and b = 0.

So, the slope of the line is 4 and the y-intercept is 0.

This means that the line passes through the origin (0,0) and rises 4 units for every 1 unit it moves to the right.

Therefore, by slope answer will be 4 and 0.

What is the value of x?​

Answers

Answer:

x = 98

Step-by-step explanation:

x = 53 + 45

x = 98

note: the measure of an ext. angle of a triangle is equal to the sum of the two non-adjacent interior angles.

Answer:

98

sum of angle in this triangle = 180

180-(53+45) = 82

so, the third angle is 82 degrees.

moving forward, the third angle (82 degrees) and angle x are straight line angle,

therefore, x + 82 = 180

x =180-82

x=98

When liquid water is confined in a tube, its surface (meniscus) has a concave shape because water wets the surface and creeps up the side. Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass.

Answers

Answer:

0.0390cm/min

Step-by-step explanation:

We are expected to do a unit conversion here.

let us convert days to minutes first

6.5days to minutes

1 day has 1440miuntes

6.5 days has x minute

cross multiply we have

x=6.5x1440

x=9360minute

let us convert yards to cm

1 yard to 91.44 cm

4 yards has xcm

cross multiply we have

x=4x91.44

x=365.76cm

the speed in cm per mins is

speed=365.76/9360m

An automobile manufacturer is preparing a shipment of cars and trucks on a cargo ship that can carry 21,600 Tons. The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each. For a different shipment, cars are loaded first, and then trucks are loaded afterwards. Write an equation you could enter into a calculator or a spreadsheet tool to find the number of trucks that can be shipped if the number of cars is known. Let x=number of cars (input) and Let y=number of trucks (output)

Answers

Answer:

Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]

Step-by-step explanation:

A cargo ship can carry 21,600 Tons.

Let x denotes number of cars and y denotes number of trucks.

The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each.

Therefore,

[tex]3.6x+7.5y=21,600[/tex]

Now write y in terms of x.

[tex]7.5y=21,600-3.6x\\y=\frac{21,600-3.6x}{7.5}[/tex]

Number of trucks (y) that can be shipped if the number of cars (x) is known[tex]=\frac{21,600-3.6x}{7.5}[/tex]

If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what will the resulting coordinate be?

Answers

Answer:

Step-by-step explanation:

90 degrees clockwise will result in a (+,+) answer.

90 degrees counterclockwise will result in a (-,+) answer.

Think of your quadrants.

Quadrant 1 the answer will be (+,+)

Quadrant 2 the answer will be (-,+)

Quadrant 3 the answer will be (-,-)

Quadrant 4 the answer will be (+,-)

It all depends where you are starting, so if you have to go counter clockwise from the third quadrant, your answer will be a coordinate that is (+,-).
