Diagonal FH bisect angles EFG and EHG and the angle FEH is congruent to angle FGH.

Why is the triangle congruent?

We need to check all the statements that are applicable for the diagram.

1) EFGH is a rectangle.

The above statements is not true in general. EFGH is a quadrilateral with opposites sides are equal, it may be rectangle in some cases but it is not always be a rectangle.

2). EFGH has 4 congruent sides.

The above statement is also false. EFGH has two opposite sides are congruent.

3). Diagonal FH bisect angles EFG and EHG.

The above statement is true. Triangle EFH and FGH both are isosceles triangles and hence they both have equal angles for the equal sides. Thus, it is true in all cases.

4). Diagonal FH is perpendicular to side Fe.

The above case is not true in general.

5). Angle FEH is congruent to angle FGH.

Yes, the above statement is the correct one, because both the triangles are congruent to each other.

Answer: 4

Step-by-step explanation: Divide both sides by -3 so the x is by itself. When you divide both sides by -3, you get x =4.

Answer:

4

Step-by-step explanation:

Divide -3 on both sides so that x is by itself

-3x = -12

-3      -3

-3 is cancelled out

-12 divided my -3 is 4

Since both numbers are negative it would end up positive.

If the numbers are both positive then it would be positive as well.

And if one number is positive and the other is negative then the answer would be negative.

The answer would be: 4

c - 12 = 4

Step-by-step explanation:

Hello!

Decreasing a number by something is subtracting that number with something.

c decreased by 12 can be represented as c - 12.

When something is something, we set it equal to each other. We can set that equal to 4 to find our equation.

Equation: c - 12 = 4

The equation of the line y = mx + b can be used to calculate the slope of a line m = ( y₂ - y₁ ) / ( x₂ - x₁ ) that passes through two points.

A line is defined as a curve showing the shortest distance between 2 points.

Here,

The slope of the line passing through two points ( x₁, y₁ ) and ( x₂, y₂ ) is given as :

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

The line that connects two locations has the equation y = mx + b, where m is the slope of the line and b is a constant.

We can find b, using the x, y, and m values in the equation of a line to obtain the y-intercept.

Therefore, the Slope of the line can be given as m = ( y₂ - y₁ ) / ( x₂ - x₁ ) and equation of line y = mx +b.

In, mathematics a logarithmic equation is inverse of exponential equation. That means, we can easily convert the logarithmic equation into exponential equation and vice versa. The basic form of the logarithm function can be written as  .

   [tex]log_ax=N[/tex]

where, a is the base of function or equation

            x define expression

Mathematically, if   [tex]a^N=x[/tex] is an exponential function then, this can be converted to logarithmic function as   [tex]log_ax=N[/tex].

There are many formulas that are given to us for solving several simple and complex problems based on logarithmic functions and logarithmic equations.

Some important formulas of logarithms are :

Aircraft a has 371 seats and Aircraft b has 235 seats.

A linear equation is an algebraic equation that has highest degree of 1.

The total number of seats in both aircraft is 606.

Assuming aircraft b has x number of sheets.

∴ Aircraft a has (x + 136) number of sheets.

From the question itself we can form a numerical expression which is

x + (x + 136) = 606.

2x + 136 = 606.

2x = 606 - 136.

2x = 470.

x = 470/2.

x = 235.

So, Aircraft b has 235 seats and Aircraft a has ( 235 + 136) = 371 seats.

x=2 y+5 is a tangent line to the circle x^2+y^2=5 at the point (1,-2).

This is further explained below.

Generally, the equation for is  mathematically given as

Differentiate both sides of the equation of the circle with respect to x, treating y=y(x) as a function of x:

[tex]x^2+y^2=5 \Longrightarrow 2 x+2 y \frac{\mathrm{d} y}{\mathrm{~d} x}=0 \\\\ \frac{\mathrm{d} y}{\mathrm{~d} x}=-\frac{x}{y}[/tex]

This gives the slope of any line tangent to the circle at the point (x, y). Rewriting the given line in slope-intercept form tells us its slope is

[tex]x=2 y+5 \\\\ y=\frac{1}{2} x-\frac{5}{2} \\\\ slope =\frac{1}{2}[/tex]

In order for this line to be tangent to the circle, it must intersect the circle at the point (x, y) such that

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

In the equation of the circle, we have

[tex]x^2+(-2 x)^2=5 x^2=5 \\\\ x=\pm 1 \\\\ y=\mp 2[/tex]

If x=-1, then

[tex]-1=2 y+5\\\\ y=-3 \neq 2[/tex]

If x=1, then

The profit function for the concert is presented as follows;

y = -100•x² + 2,000•x - 1,000

The maximum profit is $9,000

A profit function is one that gives the profit of a business which is the difference between the business's revenue and the costs of the business.

Profit = Revenue - Cost

Revenue = Quantity × Ticket price

Cost = Quantity × unit cost

Which gives;

y = Q•x - Q•c = Q•(x - c)

Given that the quantity, Q, varies, and Q•(x - c) is the product of two variables, a quadratic function is used as follows;

y = a•x² + b•x + c

When x = 0, y = -1000

Which gives;

y = a×0² + b×0 + c = -1000

c = -1000

When x = 3, y = 4,100

Which gives;

4,100 = a•3² + b•3 - 1000 = 9•a + 3•b - 1000

4,100 = 9•a + 3•b - 1000

5,100 = 9•a + 3•b

When x = 6, y = 7,400

Which gives;

7,400 = a•6² + b•6 - 1000 = 36•a + 6•b - 1000

7,400 = 36•a + 6•b - 1000

8,400 = 36•a + 6•b

Solving gives;

a = -100, b = 2,000

Which gives;

y = -100•x² + 2,000•x - 1,000

The profit function is therefore;

The maximum profit is therefore at point, x = -2000/(2×(-100)) = 10

Which gives;

Max profit = -100×10² + 2,000×10 - 1,000 = 9,000

The solution 'x' of the expressed logarithmic expression is 17.65.

A logarithmic equation one in which the variable x contains a logarithm.

The variable in an exponential formula is signified by an exponent. To solve exponential equations, first see if both sides of the equation can be presented as powers of the same number. Because unless you can't, start taking the common logarithm of both equation sides and solve the problem using property 7.

Now, as per the stated log expression;

3 ln x + ln 5 = 7

Apply the Power Rule on the first term of the given equation;

ln x³ + ln 5 = 7

Now, by the Product Rule, we can re-write the equation in the form;

ln (x³×5) = 7

ln (5x³) = 7

Using the exponent form of the log on both side.

e∧ln (5x³)  = e⁷

As, we have the same base for the obtained expression. Use the exponent rule;

(5x³)  = e⁷

x³ = e⁷/5

Substitute the value of exponent e = 2.72

x³ = (2.72)⁷/5

x³ = 5507.5

Take cube root on both side;

Answer:

y = - 3x - 12

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 )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 7, 9 ) and (x₂, y₂ ) = (- 5, 3 )

m = [tex]\frac{3-9}{-5-(-7)}[/tex] = [tex]\frac{-6}{-5+7}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3 , then

y = - 3x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation
