Answer:

[tex]{x,y} = {2,-3}[/tex]

Step-by-step explanation:

[tex]x - y = 5 \\\\[2] 3x - 2y = 12[/tex]    <----------- Linear equations given

Graphic Representation of the Equations: PICTURE

[tex]y + x = 5 \\-2y + 3x = 12[/tex]
Solve by Substitution :

// Solve equation [1] for the variable  [tex]x[/tex]

[tex][1] x = y + 5[/tex]

// Plug this in for variable  [tex]x[/tex]  in equation[tex][2][/tex]

[tex][2] 3*(y +5) - 2y = 12 \\ [2] y = -3[/tex]

// Solve equation [tex][2][/tex] for the variable [tex]y[/tex]

[tex][2] y = - 3[/tex]

// By now we know this much :

[tex]x = y+5 \\ y = -3[/tex]

// Use the  y  value to solve for  [tex]x[/tex]

[tex]x = (-3)+5 = 2[/tex]

Solution :

[tex]{x,y} = {2,-3}[/tex]

Answer:

4 - [tex]\sqrt{6}[/tex]

Step-by-step explanation:

Rationalise the denominator by multiplying the numerator and denominator by the conjugate of the denominator.

the conjugate of 4 + [tex]\sqrt{6}[/tex] is 4 - [tex]\sqrt{6}[/tex] , then

= [tex]\frac{10(4-\sqrt{6}) }{(4+\sqrt{6})(4-\sqrt{6}) }[/tex] ← expand denominator using FOIL

= [tex]\frac{40-10\sqrt{6} }{16-6}[/tex]

= [tex]\frac{40-10\sqrt{6} }{10}[/tex] ( divide terms on numerator/ denominator by 10 )

= 4 - [tex]\sqrt{6}[/tex]

Answer:

a) [tex]\sf x = 1.1[/tex]    b) [tex]\sf x = 1.5[/tex]

solving steps:

a)

[tex]\sf 2.6 * x = 2.86[/tex]

[tex]\sf x = \frac{2.86}{2.6}[/tex]

[tex]\sf x = 1.1[/tex]

b)

[tex]\sf x * 1.2 = 1.8[/tex]

[tex]\sf x = \frac{1.8}{1.2}[/tex]

[tex]\sf x = 1.5[/tex]

Step-by-step explanation:

since I don't see a figure here, I have to use only the written information.

we need to remember :

tan(angle) = sin(angle) / cos(angle)

so, we have here

a/b = a/6 / cos(y) = a/(6×cos(y))

a×6×cos(y) = a×b

cos(y) = a×b / (a×6) = b/6

Answer:

x = 10

Step-by-step explanation:

∠ 5 and ∠ 3 are same- side interior angles and sum to 180° , that is

10x + 5 + 8x - 5 = 180 , so

18x = 180 ( divide both sides by 18 )

x = 10

[tex] \\ [/tex]

⇢ 110 ° = 110°

[tex] \\ [/tex]

hence it is verified that value of x is 40°

Answer:

Step-by-step explanation:

In the question we arw given with three angles that are z

( Angle 1 , Angle 2 or Angle 3 aren't given in Question , we are just giving names for given angle . So that there's ease on explanation )

And we have asked to find th value of angle 1 i.e. x .

Solution : -

As we can see in the question that ,

Vertically Opposite Angles : -

When two lines intersect each other then the two angles formed by them at a specific point are equal .

[tex] \longmapsto x° + 70° = 110°[/tex]

Subtracting 70 from both sides :

[tex]\longmapsto x° + \cancel{70° }- \cancel{70° }= 110° - 70°[/tex]

On further calculation :

[tex] \longmapsto \purple{ \boxed{ \mathfrak{ x° = 40 {°} }}}[/tex]

Verification : -

We are verifying our answer by substituting value of x . So ,

Therefore, our value for x is correct

Are these the two equations?

Put them into slope-intercept form of y = mx + b

y = 5x - 1

−5x+y=10

y = 5x + 10

Both have a slope of 5, so they will not intersect.  This means there are no solutions.

The equations are x + y = 34 and 12x + 8y = 312. The number of adults and children will be 10 and 24, respectively.

In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.

Let 'x' and 'y' be the number of adults and children, respectively. Then the equation is given as,

x + y = 34               ...1

12x + 8y = 312        ...2

From equations 1 and 2, then we have

12x + 8(34 - x) = 312

12x + 272 - 8x = 312

4x = 40

x = 10

The value of 'y' is calculated as,

10 + y = 34

y = 24

Answer:

  (a)  1/2

Step-by-step explanation:

The coordinates of the point of intersection of the terminal side of angle α with the unit circle are ...

  (x, y) = (cos(α), sin(α))

When α = 60°, the x-coordinate of the terminal point is cos(60°) = 1/2.

Step-by-step explanation:

the general equation for a line is usually

y = ax + b

a is the slope (the inclination) of the line indicating how flat or steep (and up or down) the line goes. it is the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.

and b is the y-intercept, the y value for x=0, the point, where the line intercepts the y-axis.

the origin is the point (0, 0).

that gives us the y-intercept (b) right away, as this is therefore clearly the point, where the line intercepts the y-axis. so, b = 0.

and going from (0, 0) to (-2, 10) we see

x changes by -2 (from 0 to -2).

y changes by +10 (from 0 to 10).

so, the slope is +10/-2 = -5.

and the line equation is

y = -5x

[tex]\huge \text{Hello there! :)}[/tex]

Answer:

[tex]y=-5x[/tex]

Step-by-step explanation:

Given that the equation of a line passes through the origin and the point (-2,10), we can get the equation of the line below.

The slope-intercept form of the equation of the line is given as;

[tex]y=mx+b[/tex]

where m = slope and y = intercept

The formula for the slope is given as

[tex]\frac{y^{2-yx^{1} } }{x^{2-x^{1} }}[/tex]

The given points are the origin are (0,0) and (-2, 10)

[tex]m=\frac{10~-~0}{-2~-0} =\frac{10}{-2} =-5[/tex]

Now use the point-slope formula to solve for the equation of the line.

[tex](y-y^{1})=m(x-x^{1})[/tex]

For this situation, we are given the slope of -5 and (-2,10)

[tex]y-10=-5(x-(-2))[/tex]

[tex]y-10=5x-10[/tex]

[tex]Y+5x=+10-10[/tex]

[tex]y+5x=0[/tex]

[tex]y=-5x[/tex]

Therefore, the Answer is [tex]y=-5x[/tex]

Table is a way to represent the data of the two or more variable. To read the data from the table look for the value of one variable, and get the resultant value of other variable from the corresponding block.

Suppose that the countries of Brazil, Argentina, Ecuador, and Venezuela have interdependent economies.

The following table shows the imports and exports between each of these countries.

The trade of all the countries can be calculated as,

Brazil Argentina 4,691, Brazil Ecuador 4,791, Brazil Venezuela 1,526

[tex]B=4,691 +4,791 +1,526 =11008\rm millon[/tex]
