Answer:

192.5 miles

Step-by-step explanation:

let h be number of hours Anne takes to drive to her friend's house

[tex](55mph)(h) = (35mph)(h+2)[/tex]

Both sides of this equation represent the miles to her friend's home. (speed * time = distance)

We add 2 to h on the right side because the way back takes 2 hours longer than the way to her friend's home.

Now we can solve.

[tex](55)(h) = (35)(h+2)\\55h = 35h+70\\20h = 70\\h = \frac{7}{2} = 3.5[/tex]

Now that we have how long the trip to her friend's house takes, we can solve for the distance to her friend's house by using either side of our equation. I will use the left side because it is simpler.

[tex](55)(h)\\(55)(3.5)\\\boxed{192.5}[/tex]

That is the answer

It is just the angles that are next to GHI  

  this would be IHJ   and  FHG  

In the given expression, 7^x=28, as there is variable in one side while in other side there is constant, also there is no logarithmic value, so it is not possible to  solve the equation by changing the base of both sides

The basic formula has been changed to logb b a = [logc c a] / [logc c b]. It simply implies that to alter the base of a logarithm logb b a, we divide [log a] / [log b], where these logarithms might have any (same) positive number as a basis.

The change of base formula gives you the answer of a log with a different base by utilizing only log computations with a base of 10. The formula instructs you to divide the log of the number in parentheses by the log of your base.

y = -5x - 23, is the slope-intercept form of the line that has a slope of -5 and passes through the point (-4,3).

What is the slope intercept?

The slope-intercept form of a line is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To find the slope-intercept form of the line that has a slope of -5 and passes through the point (-4,3), we can use the point-slope form of a line which is y - y1 = m(x - x1), where m is the slope of the line, (x1,y1) is a point on the line.

We know the slope of the line is -5 and the point is (-4,3), so we can substitute these values into the point-slope form to get:

y - 3 = -5(x + 4)

Simplifying this equation gives:

y = -5x - 23

Hence, y = -5x - 23, is the slope-intercept form of the line that has a slope of -5 and passes through the point (-4,3).

Formula used to calculate the y-intercept when coordinates of two points are given is as follow: y = mx + c where 'm' represents the slope and 'c' represents the y-intercept.

As given in the question,

Let us consider points of two coordinates be equal to

( x₁ , y₁ ) =  ( 2, 3 )

( x₂ , y₂ ) = ( 4, 7 )

Equation of the line is equal to :

( y - y₁ ) / ( x - x₁ )  = ( y₂ - y₁ ) / ( x₂ - x₁ )

⇒ ( y - 3 ) / ( x - 2 ) = ( 7 - 3 ) / ( 4 - 2 )

⇒ ( y - 3 ) / ( x - 2 ) = 2

⇒ y - 3 = 2x - 4

⇒ y = 2x - 1

Same as y = mx + c

Here c = -1

Here y-intercept is equal to -1 by substituting x = 0 we can get                 y - intercept.

Therefore, the value of y-intercept can be calculated with the coordinates of the given points using formula given by :

The correct value of "x" is equal to 4

Step-by-step solution:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.

When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

Using Pythagoras's Theorem:-

[tex](Hypotenuse)^{2} = (Perpendicular)^{2} + (Base)^{2}[/tex]

[tex](x+1)^{2} -x^{2} =3^{2}[/tex]

[tex](x+1)^{2} -x^{2} =3^{2}[/tex]

[tex](x+1+x)(x+1-x) =3^{2}[/tex]

[tex](2x+1)(1) =3^{2}[/tex]

[tex](2x+1)(1) =9[/tex]

No matter how far they reach, parallel lines are those that do not have a shared meeting point in the same plane.

If two lines cannot collide when extended in both directions to infinity, they are said to be parallel in a plane. Throughout the entire length, there remains a constant gap between two lines.

|| is the symbol used to represent the parallel lines. Assuming that lines "a" and "b" are parallel to one another, we may indicate this using the symbol "a||b," which means "a is parallel to b."

The length of arc COD is approximately 12.56 units.

To find the radius of the circle, we can use the area of sector COD and the angle COD.

We know that the area of a sector is (angle/360) * pi * r^2, and we know that the area of sector COD is 50.24 square units. We also know that the angle COD is 90 degrees.

So we can set up the following equation:

50.24 = (90/360) * 3.14 * r^2

Solving for r, we get:

r = sqrt(50.24 / (90/360) * 3.14) = sqrt(50.24 / (0.25 * 3.14)) = sqrt(50.24 / 0.785) = sqrt(64.28) = 8 (approximately)

So the radius of the circle is approximately 8 units.

To find the length of the arc, we can use the formula of arc length which is Arc Length = (Angle/360) * 2πr

So the length of the arc COD is (90/360) * 23.148 = 4*3.14 = 12.56 (approximately).

The value of y after solving the given equation is -8.

We can calculate the value of y through the following method,

We have been provided with an exponential equation [tex]8^{y} = 16^{y+2}[/tex]

As we know, an exponential equation is an equation whose exponent or part of the exponent is a variable.

For solving an exponential equation, we need to use logarithms and their properties.

We can write [tex]8^{y}[/tex] also as [tex]2^{3y}[/tex] since we know that 2³ = 8

Similarly, we can write [tex]16^{y+2}[/tex] also as [tex]2^{4(y+2)}[/tex] since we know that [tex]2^{4}[/tex] = 16

Therefore we get the new equation as,

[tex]2^{3y}[/tex] = [tex]2^{4(y+2)}[/tex]

Now we will add log with base 10 on both the sides

Therefore the equation will become,

log₁₀ [tex]2^{3y}[/tex] = log₁₀ [tex]2^{4(y+2)}[/tex]

Since, according to the property of logarithm,

log₁₀ aᵇ = b log₁₀ a

Therefore,

3y log₁₀ 2 = 4(y + 2) log₁₀ 2

We can cancel out log₁₀ 2 on both sides

We get the equation as,

3y = 4(y + 2)

3y = 4y + 8

When the numerator and denominator of an equation are both polynomials, the expression is said to be rational. The lowest form of the numerator and denominator is used to simplify rational formulas. An algebraic fraction is another name for a rational expression.

The value of a logical statement is diminished to its simplest form or lowest terms when it is simplified. Similar to how we simplify fractions, we can simplify a rational equation. In fractions, a rational number is said to be in its simplified form if its numerator and denominator share no factors other than 1.

The result of dividing 2x^3 + x^2 - 2x + 8 by x + 2 is:

Quotient: 2x^2 - 3x + 4

Remainder: 0

The given polynomial is 2x^3 + x^2 - 2x + 8.

First we choose a term to multiply with the first term of the divisor such that we get the first term of the polynomial.

(x)(2x^2) = 2x^3

Thus, we multiply the divisor (x + 2) by 2x^2 which gives 2x^3 + 4x^2.

Now we subtract this from the polynomial which gives -3x^2 - 2x +8.

Next we multiply the divisor by -3x which gives -3x^2 - 6x. Again we subtract the same from the remaining polynomial -3x^2 - 2x +8 and get 4x + 8.

Repeating the same we multiply the divisor by 4 which gives 4x + 8. Subtracting the same from the remaining polynomial 4x + 8 we get the remainder 0.
