We will proceed as follows in order to get an equivalent expression:

So, one equivalent expression is 2x + 4.

Let's try to factorize this polynomial

in the blank spaces we have to put numbers that multiplied are 24, and substracted are +2. So we have 6 and 4

So the factored form of the polynomial is (x+6)(x-4)

The solved equation for h is h= S/ pi x r^2-1/3.

The problem we are dealing with here is related to the literal equation,  where a literal equation is an equation that comprises basically letters. Formulas are an illustration of strict equations. Each variable within the condition "truly" speaks to an important part of the full relationship expressed by the equation. To illuminate a literal equation implies modifying the equation so a different variable stands alone on one side of the equals sign. We got to be told which variable we need to solve.

For the given equation,S=  1/3 x pi x r^2 + pi x r^2 x h

for th the equation will be

=>S=  pi x r^2(1/3 +h)

=>S/ pi x r^2= 1/3+h

=>h= S/ pi x r^2-1/3

Solution:

Let d represent the number of hours Bobby walks dogs,

and w be the number of hours she works at the car wash.

Given that she can work at most 20 hours next week, this implies that the total number of hours she works is expressed as

If her dog-walking job pays her $6 per hour, this implies that for d number of hours, she will earn

and her iob as a car wash attendant pays her $10 per hour, similarly for w number of hours, she will earn

Given that she needs to earn at least $150, this implies that her total earnings will be expressed as

Hence, the system of inequalities that represents Bobby's situation is:

The equation is equivalent to −(5−x) = 5−x is -5+x = 5-x

Answer:

x^6

Step-by-step explanation:

Given X¹⁰ ÷ (x² X x³ ÷ x) : Simplify.

We know the law of exponents which states that

a^m x a^n = a^m + n

a^m / a^n = a^m - n

So the problem is x^10 / (x^2 x x^3 / x)

So we have x^10 / x ^5 / x

             x ^10 / x ^5 - 1

           x^10 / x^4

       x ^10 -

x^6

After simplifying we get x^6

Chris, this is the solution to the exercise:

• Point 1 = (7, 6)

• Point 2, (0, 2)

Now, let's use the formula to calculate the distance between the two points, as follows:

d = √(0 - 7)² + (2 - 6)²

d = √-7² + (-4)

d = √49 + 16

d = √65

d = 8.0622

Points are (1, -3)

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities. In mathematics, an equation is a relationship between two expressions that is expressed as an equality on each side of the equal to sign. An equation would be 3y = 16, for instance.

Given Data

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

Points (-1, -5)

The line's general equation is y=ax+b.

Since we are aware that the slope is -[tex]\frac{1}{2}[/tex], an is equal to -[tex]\frac{1}{2}[/tex].

We also understand that if x = -1, then y = -5.

Let's connect it:

-5=1*(-1)+b

-5=-1+b

b= -4

So, y=x -4 is the line's equation.

Let x = 1

y = 1 - 4

Answer:

The answer is 10 and one half pounds

Explanation:

3.5/7 = 2

21/2 = 10.5

10 and one half pounds use to make 21 small vases.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Sandy uses clay= 3 1/2 pounds for 7 vase

So, for 1 vase amount of clay used

= 7/2 x 1/7

= 1/2 pounds

Now, for 21 small vases amount of clay used

=21 x 1/2

= 21/2

= 10 1/2 pounds.

The linear model that determines your profit or loss based on the number of sandwiches is 15y-275, where y is the number of sandwiches sold.

A continuous response variable is described as a function of one or more predictor variables in a linear model. They can assist you in comprehending and forecasting the behaviour of complex systems, as well as analyzing experimental, financial, and biological data. Linear regression is a statistical technique for developing a linear model.

It is given that the investment amount is $275.

The charge per sandwich is $15

So, generated revenue= 15 y

where y is the number of sold sandwiches.

Profit/ Loss= Revenue- total investment= 15y-275

So, the linear model determining the profit or loss is 15y-275, where y is the number of sandwiches.

After rounding off the number we get ; 9,300

When a number is rounded to the closest thousand, it is changed to an approximated value that is simpler to recall and utilize. The closest value to the supplied integer is this value, which is a multiple of 1000. For instance, 342984 becomes 343000 if it is rounded to the closest thousand.

So as in this question the number given is 9340

Since we have to round it off to thousands

One way of simplifying the given expression is by factoring them, and then simplifying the common terms.

So, we need to write:

The constants a and b are the zeros of the first expression, and the constants c and d are the zeros of the second expression.

So, we can find those zeros using the quadratic formula. We obtain, for the first expression:

And, for the second expression, we obtain:

Then, we can write:

Thus, the given function can be simplified as follows:

Therefore, the answer is:

Notice that each new term is half the previous one. For example, 32 is half 64, 16 is half 32, and so on.

Having said that, the constant ratio is 1/2. Using this ratio we can find the next three terms.

The average distance between students in public is smaller than that in private.

While the data for the public appears to closely follow a bimodal distribution, the data for the private appears to be negatively skewed, meaning that the tail is lopsided to the left. However, it might be nearly symmetrical. While the modal class for the public is 11–50, it is 101–500 for private.

While the mean for public data is close to 50, it is close to 100 for private data.

Therefore, it is clear from the graphs that students' average distances from Public are closer than those from Private.

The cost of the cotton candy that Jessica purchased is $3.

The first step is to determine total amount spent on snacks. The total amount spent is the sum of the amount paid by Tom and Jessica.

Total amount spent = $9 + $4 = $13

Two ice creams and one cotton candy is bought. This can be represented with:

$13 = total cost of ice cream + cost of the cotton candy

$13 = (2 x$5) + c

SOLUTION

Given the question in the question tab, the following are the solution steps to answer the question.

STEP 1: Define an equation with one solution

You can tell that an equation has one solution if you solve the equation and get a variable equal to a number. A system of linear equations has one solution when the graphs intersect at a point.

STEP 2: Examine the options

An equation is said to have "no solution" when the coefficients are the same and the constants are different as seen below:

When the coefficients are the same and the constants are the same, the equation is said to have "infinitely many solutions as seen below:

When the coefficients are different, the equation is said to have one solution as seen below:

Hence, the answer is:

The parent function of g(x) = x + 9 is the function f(x) = x.

The function f(x) = x is a linear function, that is, it has degree 1 (the higher exponent of the variable x is 1).

In order to get g(x) from f(x), we can see that the function value was increased by 9 units:

Adding 9 units to the function means we have a translation of 9 units up.

Therefore the correct option is the third one.

Graphing g(x), we have:

Answer:

  B. The parabola opens upward. It is stretched taller by a factor of 3.

Step-by-step explanation:

You want to know how the quadratic opens, and how it is stretched or compressed, given its equation is f(x) = -3x^2 +6x +5.

The "leading coefficient" is the coefficient of the highest-degree term. That term is -3x^2, and its coefficient is -3.

The minus sign tells you the parabola opens downward.

The magnitude of 3 tells you the parabola is stretched vertically (taller) by a factor of 3.

The inequality that can be used to calculate total cost (T) based on the number of guests (g) is 225 + 15g ≤ 1000.

If you have a total budget of $1000, 51.67 guests can be invited.

Total cost = Cost of hall rent + Caterer's charge per guest(Number of guests)

225 + 15g ≤ T

If you have a total budget of $1000

225 + 15g ≤ T

225 + 15g ≤ 1000

15g ≤ 1000 - 225

15g ≤ 775

g ≤ 775 / 15

g ≤ 51.66666666666666

Approximately,

g ≤ 51.67
