The line shown in the graph have slope of line as 13/27 with rise 13 and run 27.

What is slope of line?
The definition of slope in mathematics is pretty close to how we normally define it. Slope is a mathematical term used to indicate a line's steepness and direction. A line's slope can be inferred from its graph alone, especially in comparison to other lines shown on the same coordinate plane.

The formula to calculate the slope of any line is given by:

[tex]slope = \frac{rise}{run}[/tex]

We know that, '

rise = y₂ - y₁

run = x₂ - x₁

As we can see in the graph

x₂ = 10, y₂ = 3

x₁ = -7,  y₁ = -10

putting the values in above formula

rise = y₂ - y₁ = 3 -(-10) = 13

run = x₂ - x₁ = 10 -(17) = 27

so, slope = 13/27

Hence the slope of the line shown in graph is 13/27.

Table A represents a function.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Functions are crucial instruments in the creation of mathematical models because we continually develop beliefs about connections between variables in nature and society. Typically, functions in school mathematics contain numerical inputs and outputs and are frequently specified by algebraic expressions.

Answer:

g(x) = 4x - 23

Step-by-step explanation:

We will assume a linear function for g(x)

This will be of the form g(x) = ax + b where a and b are constants

Given the info,

g(3) = a(3) + b = -11

g(7) = a(7) + b = 5

Thus we have two equations in a and b
3a + b = -11  [1]
7a + b = 5    [2]

Subtract [1] from [2]:
7a + b - (3a + b) = 5 - (-11)
7a + b - 3a - b = 5 + 11

4a = 16

a = 4

Substitute for a in equation [2]:

4(7) + b = 5
28 + b = 5

b = 5-28 = -23

So equation of g(x) is
g(x) = 4x - 23

The years when the spending be more than $66 billion is in 4 years time.

A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

The equation is given as y=12.7x+15.2 and the amount is $66 billion. Therefore, the value of x will be:

y=12.7x+15.2

66 = 12.7x + 15.2

Collect like terms

12.7x = 66 - 15.2

We are given the linear equation;

4x[tex]^{1/3}[/tex] - x = 0

Answer:

Step-by-step explanation:

Systems of equations may be solved in one of two manners:  substitution and graphing.  This requaests they be solved by substitution, but I'll add the graphing solution, also.

Substitution:

We want to eliminate one of the two variables to result in an expression that only has one of the two remaining.  We can do that by manipluating one of the equations such that, when it is combined with the other, results in the elimination of one of the variables.

Given:

-2x-y=-9

5x-2y=18

we can multiply or divide one of the equations so that one of the terms has equal, but opposite, values.  We could multiply the first equation by 2.5 so that it becomes -5x -2.5y = 9*(2.5).  Then it could be added to the second to eliminate the x term.

My preference is to find a way to avoid fracticious fractions, so I will multiply the first equation by -2 so that we can eliminate y:

-2*(-2x-y =-9)

4x+2y = 18

No add this to the second equation:

  4x+2y = 18

  5x-2y = 18

   9x = 36

     x = 4

Since x = 4:

-2x-y=-9

-2*(4)-y=-9

-8 - y = -9

y = 1

The solution is (4,1).  It is the point the satisfies both equations.

-2x-y=-9

-2(4)-(1)=-9  

-8-1=-9   YES

----

5x-2y=18

5(4)-2(1)=18

20 - 2 = 18  YES

Graphing:

The solution to these equations is the point at which the lines intersect.  See the attached graph.  The lines intersect at (4,1).

100000 = 10n

Divide both sides by 10.

100000 / 10 = n

Step-by-step explanation:

-they’re common multiples of 2, 4, 8, and 10

(a)

In the given diagram,

∠α and ∠β can be determined using trigonometric functions,

tan α = Opposite side/Adjacent side

⇒ tan α = 4/6

⇒ tan α = 2/3

⇒ α = tan^-1 (2/3)

⇒ α = 33.7°

Similarly,

tan (α + β) = 4+4/6

⇒ tan (α + β) = 8/6

⇒ tan (α + β) = 4/3

⇒ (α + β) = tan^-1 (4/3) = 53.1°

⇒ 33.7 + β = 53.1°

⇒ β = 19.4°

(b)

For the cables adjacent to the perpendicular height, i.e., adjacent to ∠α, on both the sides

Cable length^2 = 4^2 + 6^2 .............................. (Pythagoras theorem)

⇒ Cable length^2 = 16 + 36

⇒ Cable length^2 = 52

⇒ Cable length = 7.21 m

For the cables far from the perpendicular, on both the sides,

Cable length^2 = 6^2 + 8^2 .............................. (Pythagoras theorem)

⇒ Cable length^2 = 36 + 64

⇒ Cable length^2 = 100

⇒ Cable length = 10 m
