Answer:

Rewrite as an equation.

log

9(729)=x

Rewrite

log

9(729)=x

in exponential form using the definition of a logarithm. If

x and b

are positive real numbers and b

does not equal 1, then log b(x)=y is equivalent to by=x. 9x=729

Create expressions in the equation that all have equal bases.

(32)x=3

Rewrite

(32)x as 32x. 32x=36

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

2 x 3=6

Solve for

x.x=3

The variable  x

is equal to

3.3

Step-by-step explanation:

The expression not equal to 729 is 6³

Exponents, also known as powers, are values that show how many times to multiply a base number by itself. For example, 43 is telling you to multiply four by itself three time:4³= 4 × 4 × 4 = 64

Given here  3⁶= 3×3×3×3×3×3

                        = 729

                    6³ = 6×6×6

                         = 216

                    9³ = 9×9×9

                         = 729

Hence 6³ is the expression not equal to 729

Step-by-step explanation:

Answer:

y = x + 3

y = 3x + 1

Step-by-step explanation:

This does it in two equations.

y = x + 3 and  y = 3x + 1 equation will send 2 different lines through the coins to capture them

using the slope intercept equation,

y = mx + b

m = slope

b = y-intercept

let's pick 2 coordinate from the graph,

(-2, 1)(-1, 2)

m = 2 - 1 / -1 - (-2)  = 1 / 1 = 1

1 =  -2 + b

b = 3

Therefore,

y = x + 3

let check for another equation that will work for another line. Let's use the coordinates (-1, -2)(0, 1) to find slope.

Therefore,

m = 1 - (-2) / 0 - (-1) = 3 / 1 = 3

y = 3x + b

1 = 3(0) + b

b = 1

y = 3x + 1

Answer:

Step-by-step explanation:

The cost of each plan (y) is the sum of the initial fee and the product of the mileage charge and the number of miles (x).

First Plan: y = 40 +0.13x

Second Plan: y = 53 +0.08x

__

We can find when the costs are the same by solving this system of equations. A way to do that is to subtract the second equation from the first:

  (y) -(y) = (40 +0.13x) -(53 +0.08x)

  0 = -13 +0.05x

Multiplying by 20 gives ...

  0 = -260 +x

Adding 260, we have ...

  x = 260

The plans cost the same for 260 miles of driving.

__

The cost of the plans for that distance is ...

  y = 40 +0.13x = 40 +0.13(260) = 40 +33.80

  y = 73.80

The cost when the two plans cost the same is $73.80.

Answer:

Step-by-step explanation:

What you must do for this case first is to find the equation of the line.

We have then that by substituting the values of x = 0 and x = 3 we obtain:

y = 0.2

y = 2.2

Respectively.

So, the line is:

y = 2 / 3x + 1/5

Then, the points that satisfy the inequality are all those of the shaded region.

Answer:

The inequality is:

y ≤ 2 / 3x + 1/5

Answer:

square root of five = 2.2360679775

Answer:

2.23

Step-by-step explanation:

first, what does square root means? it means a number which produces a specified quantity when multiplied by itself.

so in this suation we need to find a number that is multiplied by itself to get 5.

5 does not have a square root in whole numbers it has a square root in decimal. we need to find the closest number to 5 that has a square root and that is a 4. the square root of 4 is 2 so, the 5 square root is gonna be 2 and something decimal.

lets multiply :

2.25*2.25 = 5.0625

the number 5.0635 is a little too big for the number 5

now lets multiply :

2.23*2.23 = 4.9729

if we round the number 4.9729 it will equal 5

so, the square root of 5 is 2.23

[tex]\sqrt{5} = 2.23[/tex]

The height of the center of this circular clock  (x - 4)² + (y - 7)² = 1, is 7 meters above the ground.

The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.

The standard equation of a circle is x² + y² = r².

The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².

We know the standard formula of a circle is  x² + y² = r² centered at the origin.

Now, (x - h)² + (y - k)² = r² represents a circle centered at (h, k).

Given, The equation (x - 4)² + (y - 7)² = 1, with units in meters, represents the location of the clock relative to the bottom left corner of the wall.

Therefore, (4, 7) is the center of the clock in the x-y axis when the y-axis represents height so it is 7 meters above the ground.

Answer:

measure 2 has to be 109 due to the alternate interior angles theorem. Measure 3 has to be 71 due to the supplementary angles theorem.

Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—is known as the vertex.

Given two parallel lines a transversal.

Angles 8 and 2 are alternate interior angles.

m∠8 = m∠2

m∠2 = 108°

Now,m∠2 and m∠3 are supplementary angles.

Therefore,m∠3 = 180° - 108° = 71°

Hence "Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively".
