The equatiοn 9 -3 = 6 can be written in different fοrms, but the correct one is 9 = 3 + 6.

Every cοmbinatiοn οf a number, a variables, and οperatiοn symbοls is cοnsidered an expressiοn. An equatiοn is created by cοmbining twο expressiοns and jοining them with the equal sign.

Cοnditiοns οn the parameters are fοund in simple equatiοns. It is clear frοm an equatiοn that the answer οn the left and right are equivalent. The expressiοn tο the left οf the symbοl "=" is the LHS, while the expressiοn tο the right is the RHS. With the fοrm y = "sοme expressiοn invοlving x," a sοlutiοn invοlving x and y can be expressed, such as y = f. ( x). This final statement, which may be interpreted as "y equals f οf x," denοtes that y is a cοefficient οf x.

Answer:

a) r = 9.7 m

Step-by-step explanation:

      CD = CE + ED

            = 9 + r +r

            = 9 + 2r

If a tangent and a secant are drawn from a common point outside the circle, then

                     CE * CD = CB *CB

               9 *  ( 9 + 2r) = 16 * 16       {Distributive property}

               9*9 + 9*2r   = 256

                   81 + 18r    = 256

Subtract 81 from both sides,

                            18r   = 256 - 81

                               18r = 175

Using geometry, we can find that the length of the line segment AC as per the distance between two points is= 18 ft.

What are line segments?

In geometry, a line segment's borders are determined by two distinct points on the line. Any portion of a line that connects two places is referred to as a line segment.

A segment has an endpoint, whereas a line doesn't.

What are some examples of line segments in the real world?

a scale, a ruler, a stick, and a boundary line.

Thus, the length of the line segment AC is = 18ft.

The inequality x ≤ 3 indicates how many different bicycle outfits she can purchase.

She has $560 to spend at a bike shop on new accessories and clothing for riding.

For $425.05. she spends on a brand-new bicycle.

She spends $15.19 for each of four bicycle reflectors and $15.79 on a pair of cycling gloves.

She intends to use all or part of the remaining funds to purchase new bicycle clothing at $29.20 each.

The disparity that can be used to calculate how many garments she can purchase for her budget is as follows:

let

x = the number of garments

Therefore,

425.05 + 15.19(4) + 15.79 + 29.20x ≤ 560

425.05 + 60.76 + 15.79 + 29.20x ≤ 560

29.20x ≤ 560 - 425.05 - 60.76 - 15.79

29.20x ≤ 58.4

The range of lengths Brett can use for the third piece of steel is 4 in. < x < 20 in.

The Triangle is a polygon with three line segments as its boundaries. That is the tiniest polygon imaginable. Three vertices, three internal angles, and three sides make up a triangle.

The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for every triangle, the sum of the lengths of the first two sides is always higher than the length of the third side. In other terms, this theorem states that a straight line is always the shortest distance between any two places.

Using the triangle inequality theorem we have:

8 + 12 > x

x + 8 > 12

x + 12 > 8

20 > x

x > 4

x > -4

Therefore, the range of lengths Brett can use for the third piece of steel is 4 in. < x < 20 in.

Answer:

Step-by-step explanation:

The statement "85% of 'a' is 'b'" can be represented mathematically as:

0.85a = b

This means that 'b' is 85% of 'a'.

To answer the question:

a = b/0.85

So, a is equal to 'b' divided by 0.85.

Therefore, the correct option is (a) a=b.

Answer:

1.65 pints

Step-by-step explanation:

If Tara used 6.6 pints of white and blue paint combined, and 3/4 of that amount is white paint, then we can find the amount of white paint she used by multiplying 6.6 by 3/4:

6.6 x 3/4 = 4.95

So Tara used 4.95 pints of white paint to paint her bedroom walls.

To find out how much blue paint she used, we can subtract the amount of white paint from the total amount of paint:

6.6 - 4.95 = 1.65

Therefore, Tara used 1.65 pints of blue paint to paint her bedroom walls.

Answer:

The principal square root of a non-negative real number is the positive square root. For example, the principal square root of 25 is 5, since 5^2 = 25.

When solving radical polynomials, the principal square root is used because it is the most commonly used square root. In many contexts, including mathematical and scientific calculations, the principal square root is the default choice unless otherwise specified. Additionally, when working with radical expressions, we often simplify expressions by taking the principal square root, as it can help us to simplify calculations and express answers more clearly.

Pearl's mortgage payment would be $678.47 per month.

A mortgage is a type of loan that is used to finance the purchase of real estate, such as a house or a piece of land. When a person takes out a mortgage, they borrow money from a lender (usually a bank or other financial institution) to buy the property, and they agree to pay back the loan over a set period of time, typically 15 to 30 years.

In the given question,

To calculate Pearl's mortgage, we need to first determine the amount of her down payment.

Down payment = 10% x $130,000

Down payment = $13,000

The amount that Pearl needs to finance with her mortgage is:

$130,000 - $13,000 = $117,000

To calculate the mortgage payment, we can use the formula for a fixed-rate mortgage:

Mortgage Payment = P * r * (1 + r)^n / ((1 + r)^n - 1)

Where:

P = Principal (amount borrowed)

r = Monthly interest rate (annual rate divided by 12)

n = Number of monthly payments (30 years x 12 months per year)

Monthly interest rate = 6.3% / 12 = 0.00525

Number of monthly payments = 30 years x 12 months = 360

Using these values, we can calculate the monthly mortgage payment:

Mortgage Payment = $117,000 * 0.00525 * (1 + 0.00525)^360 / ((1 + 0.00525)^360 - 1)

Mortgage Payment = $678.47 (rounded to the nearest cent)

Therefore, Pearl's mortgage payment would be $678.47 per month.

To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):

x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)

Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:

x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7

Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.

Note that this expression is defined for all values of x and y except for x=0.

The net that represents this solid figure is diagram D.

A solid figure is a three-dimensional geometric shape that has length, width, and height. It is also called a three-dimensional or 3D figure. Some examples of solid figures include cubes, spheres, cylinders, cones, and pyramids.

Solid figures are different from two-dimensional shapes, which only have length and width. In contrast, solid figures have depth or thickness, making them more complex and interesting.

Solid figures can be classified based on their properties, such as the number of faces, vertices, and edges they have. For example, a cube has six faces, eight vertices, and 12 edges, while a sphere has no faces, vertices, or edges.

For the given function the intercepts are:

x-intercept: x = -4

y-intercept: y = 12.

Here we have a table that defines a function, and we want to find the intercepts of said function.

We can assume it is linear, then the slope of the function will be given by:

a = (9 - 3)/(-1 + 3) = 6/2 = 3

The linear function is like:

y = 3x + b

To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.

18 = 3*2 + b

18 = 6 + b

18 - 6 = b = 12

The linear function is:

y = 3x + 12

The x-intercept is the value of x when y = 0

0 = 3*x + 12

-12 = 3x

-12/3 = x = -4

And the y-intercept is the value of y when x = 0.

y = 3*0 + 12
