11.8 has one decimal place so your answer will have one too

59.0 which is the same as 59

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).

(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

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.

Answer:

1.1l +0.4+0.3+0.5

answer = 2litres 3milimetres

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

Step-by-step explanation:

the area (A) of a triangle is calculated as

here b = 2x - 6 , h = 4 and A = 60 , then

[tex]\frac{1}{2}[/tex] × 4 ×(2x - 6) = 60

2(2x - 6) = 60 ( divide both sides by 2 )

2x - 6 = 30 ( add 6 to both sides )

2x = 36 ( divide both sides by 2 )

x = 18

2x - 6 = 2(18) - 6 = 36 - 6 = 30

perimeter (P) is the sum of the 3 sides , so

Since 1978, the graph shows the dollar cost of a medical procedure as a function of time, d. In 1993 year does it represent.

The cost of treatment when d = 1 is $273

Given that,

Since 1978, the graph shows the dollar cost of a medical procedure as a function of time, d.

We have to find in which year does it represent.

Let the equation be

y=150×[tex]e^{at}[/tex]

Where t is the time for year

According to the figure,

y pass (0.5,202.50)

We get,

202.5=150×[tex]e^{0.5a}[/tex]

[tex]e^{0.5a}[/tex]=1.35

Now,

150×(1.35)³=150×[tex](e^{0.5a})^{3}[/tex]

150×(1.35)³=150×[tex]e^{1.5a}[/tex]

1.5 is for 15 years.

1978+15=1993.

Therefore, in 1993 year does it represent.

The graph represents an exponential function:

[tex]$$y=a b^x$$[/tex]

When (x, y)=(0,150), the equation becomes

[tex]$$\begin{aligned}&150=a b^0 \\&a=150\end{aligned}$$[/tex]

When (x, y)=(0.5,202.5), the equation becomes [tex]$202.5=a b^{0.5}$[/tex]

Substitute 150 for a

[tex]$$202.5=150 b^{0.5}$$[/tex]

Divide both sides by 150

[tex]$$1.35=b^{0.5}$$[/tex]

Square both sides

b=1.82

So, the equation of the graph is:

y=150 * 1.82^x

When x=1, we have:

[tex]$$\begin{aligned}&y=150 * 1.82^1 \\&y=273\end{aligned}$$[/tex]
