Answer:

y-3x=4

Step-by-step explanation:

1-4/-1-0=3

1 = 3(-1)+b

1=-3+b

b=4

The equation of linear equation in standard form consisting points (-1, 1) and (0, 4) is,

⇒ y = 3x + 4

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (-1, 1) and (0, 4)

Now,

Since, The equation of line passes through the points (-1, 1) and (0, 4).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (4 - 1) / (0 - (-1))

m = 3 / 1

m = 3

Thus, The equation of line with slope 3 is,

⇒ y - 1 = 3 (x - (-1))

⇒ y - 1 = 3 (x + 1)

⇒ y - 1 = 3x + 3

⇒ y = 3x + 3 + 1

⇒ y = 3x + 4

Therefore, The equation of linear equation in standard form is,

⇒ y = 3x + 4

Step-by-step explanation:

Answer:

I think its D but I'm not that sure about it.

Step-by-step explanation:

Because three fifths less than two thirds, the slope of te climbing equipment at the playground is greater.

Answer:

A)

Step-by-step explanation:

A piece of climbing equipment at a playground is 6 feet high and extends 4 feet horizontally.

Therefore its slope = length of the equipment vertically / length of equipment horizontally

=  6/4 = 3/2 = 1.5

And, A piece of climbing equipment at a gym is 10 feet high and extends 6 feet horizontally.

Therefore slope, =  10/6 = 5/3=1.67 (approx)

Since, >

Therefore, Five-thirds greater-than three-halves, the slope of the climbing equipment at the gym is greater

Answer:

xy & 10xy.

Step-by-step explanation:

The original value is 32xy. Because it has the variable xy, you need to choose values with those same variables. This leaves xy and 10xy.

Answer: no solution

Why?: because when a problem has no solution you'll end up with a statement that's false. For example: 0=1 This is false because we know zero can't equal one. ... So, we say this problem has no solution. This means no matter what number you put in for the variable x, you will never get anything that equals one another. hope it helps!

Answer:

im pretty sure it would be -8-(-6)=-2 for the first one

Given:

Basic cost = $45

Cost of long distance calls = $0.10 per minute

To find:

The total cost if you had 45 long distance minutes.

Solution:

Let the total cost be y for x minutes long distance calls.

Cost of long distance calls for one minute = $0.10

Cost of long distance calls for x minute = $0.10x

Total cost = Basic cost + Cost of long distance calls for x minute

[tex]y=45+0.10x[/tex]

Substitute x=45, to find the total cost if you had 45 long distance minutes.

[tex]y=45+0.10(45)[/tex]

[tex]y=45+4.5[/tex]

[tex]y=49.5[/tex]

Therefore, the total cost if you had 45 long distance minutes is $49.5.

Answer:

The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings, and the wavelength, determine the frequency of the sound produced. The strings on a guitar have different thickness but may be made of similar material. They have different linear densities, where the linear density is defined as the mass per length,

μ

=

mass of string

length of string

=

m

l

.

In this chapter, we consider only string with a constant linear density. If the linear density is constant, then the mass

(

Δ

m

)

of a small length of string

(

Δ

x

)

is

Δ

m

=

μ

.

For example, if the string has a length of 2.00 m and a mass of 0.06 kg, then the linear density is

μ

=

0.06

kg

2.00

m

=

0.03

If a 1.00-mm section is cut from the string, the mass of the 1.00-mm length is

The guitar also has a method to change the tension of the strings. The tension of the strings is adjusted by turning spindles, called the tuning pegs, around which the strings are wrapped. For the guitar, the linear density of the string and the tension in the string determine the speed of the waves in the string and the frequency of the sound produced is proportional to the wave speed.
