Answer:

y = [tex]\frac{2}{5}[/tex] x - 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = [tex]\frac{2}{5}[/tex] and line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = [tex]\frac{2}{5}[/tex] x - 3 ← equation of line

Answer: Yes it does.

Step-by-step explanation:

The 3 angles in a triangle always add up to be 180.

Call the smallest angle as x
-> The 3 angles are x, 4/3x and 5/3x
-> 4x = 180
-> 45

So, the sizes of the 3 angles are 45, 60 and 75.

The equation for the line parallel to y=1/4x+1 that passes through the point (6,-2) is x-4y=14 as the slope for both lines are equal and using slope-point form of equation.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

The equation of a straight line that passes through a given point and is inclined at a specific angle to the x-axis can be found using the point slope form.

Here,

The slope for the line will be 1/4 and the given points will be (6,-2) so the equation for the line is

y-y1=m(x-x1)

y+2=1/4(x-6)

4y+8=x-6

x-4y=14

Given that both lines have an equal slope and using the slope-point form of equation, the equation for the line parallel to y=1/4x+1 passing through the point (6,-2) is x-4y=14.

An nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).

As given in the question,

Number of zeros of the polynomial function N = 3

Real and complex zeros = 3, 2i , -2i

Function value f(-1) = 20

f(x) = k (x-3)(x-2i)(x+2i)

⇒f(x) = k(x-3)(x²-4i²)

⇒f(x) =k(x-3)(x²+4)

⇒f(-1) = k(-1-3)((-1)² +4)

⇒ 20 =k(-4)(5)

⇒k =-1

Now , f(x) = (-1)((x-3)(x²+4)

               = (-1)(x³ -3x²+4x -12)

Therefore, nth- degree polynomial function with real coefficient for N = 3 ; 3, 2i are zeros ; f(-1) =20 is given by f(x) = (-1)( x³ -3x²+4x -12).

Answer:

Weight on Mars:  1,475.32 kg

Step-by-step explanation:

The formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2.

If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

Mass is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram.

Given,

The mass of a space rover is 3900 kg.

We need to check what is its mass in Mars.

The mass of space rover  in Mars will also be same 3900 kg because the mars is same quantity it wont change according to place or time, it remains constant. Where as weight would be changed.

The mass of the object is always constant, anywhere it is on the Earth or Moon or any other planet.

Hence, If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

The total change to Rapunzel's score as an integer is (x - 30), where x is the initial score.

How can linear addition and subtraction be carried out?
In math, addition is the process of adding two or more integers together. Addends are the numbers that are added, while the total refers to the outcome of the operation. It is one of the fundamental mathematical operations we employ on a daily basis.
An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol, or, denotes subtraction.

Let the initial score of Rapunzel be = x
Given, she first lost nine points thrice and then three points, thus her score is: x - (9*3) - 3 = (x - 30) points.

The number of binder on the bookshelf is one

The given parameters are:

Width of the bookshelf = 31 3/4 inches

Width of the binders = 28 inches

From the question, we understand that the binders are stacked side by side

This means that the quotient of the width of the bookshelf and the width of the binder will give the number of binders

So, we have

Number of binders = Width of the bookshelf/Width of the binders

This gives

Number of binders = (31 3/4)/28

Evaluate the quotient

Number of binders = 1.13

Answer:

Step-by-step explanation:

due to the vertical line test it only passes through the x point once

By applying the distributive property of multiplication, the students that are correct in their approach to solving the problem are: Nico, Raj and Sandra.

In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 5/2 as follows:

2/5(5 + x) = 8

Multiplying both sides by 5/2, we have:

5/2 × 2/5(5 + x) = 8 × 5/2

5 + x = 40/2

5 + x = 20

Subtracting 5 from both sides, we have:

5 + x - 5 = 20 - 5

x = 15

In order to open the bracket and isolate the variable x, we would first of all multiply both sides by 1/2 and then 5 as follows:

2/5(5 + x) = 8

Multiplying both sides by 1/2, we have:

1/2 × 2/5(5 + x) = 8 × 1/2

1/5(5 + x) = 4

Multiplying both sides by 5, we have:

5 × 1/5(5 + x) = 4 × 5

5 + x = 20

Subtracting 5 from both sides, we have:

5 + x - 5 = 20 - 5

x = 15

In order to open the bracket and isolate the variable x, we would apply the distributive property of multiplication:

2/5(5 + x) = 8

2/5 × 5 + 2/5 × x = 8

2 + 2x/5 = 8

Subtracting 2 from both sides, we have:

2 - 2 + 2x/5 = 8 - 2

2x/5 = 6

Multiplying both sides by 5/2, we have:

5/2 × 2x/5 = 5/2 × 6

x = 30/2

x = 15.

The meaning of vertical intercept in this context can be inferred from the options to mean that the helicopter took off from a height of 50 ft.

In a linear problem or a graph, the vertical intercept, which is also known as the y-intercept, refers to the value of y when the value of x is 0.

Assuming y in this problem refers to the height and x refers to the minutes, the vertical intercept would be the height at 0 minutes.

If the vertical intercept is 50 ft then it means that the helicopter took off from 50 feet because at takeoff, the value of x would be 0 minutes.
