Answer:

8x + 5y = 3

Step-by-step explanation:

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given 8x = - 5y + 3 ( add 5y to both sides )

8x + 5y = 3 ← in standard form

1. -4 and 3/10 and 4.51010910921... are all rational numbers.

2. Yes 81 is a perfect square because its square root is 9 which is a real number.

3. 5

4. Well the closest perfect square to 52 is 49 and 64. 52 is closer to 49 and the square root of 49 is 7 so the estimated value of the square root of 52 is about 7.

False- every square root is not rational because some aren't perfect squares, meaning the result is a decimal that keeps going forever.

5. (x+6, y-5)

The equation of proportional situation is y = ax.

Therefore your answer is y = -2x + 14

Answer:

Answer (a):

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Answer (b)

9 large dogs.

Step-by-step explanation:

Paws at Play made a total of $1234 grooming 22 dogs.

Paws at Play charges $43 to groom each small dog and;

$75 for each large dog.

Let the number of small dogs be 's'

And the number of large dogs be 'l'

A system of equations will be:

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;

43s + 43l = 946 ... (i)

43s + 75l = 1234 ... (ii)

Subtracting (i) from (ii) we get;

32l = 288 , l = [tex]\frac{288}{32}[/tex] = 9

So there are 9 large dogs.

Answer:

x = 3

Step-by-step explanation:

m < T = m < R  (Because they are opposite angles of a parallelogram). Therefore:-

40x + 2 = 122

40x = 120

x = 120/40

x = 3

Parallelogram is the closed shaped quadrilateral which has opposite site equal and the opposite angle are equal. The value of the x is 3 units.

For the parallelogram angle T is (40x+2) degrees.

The angle R is 122 degrees.

To solve this the it should be known about the angle of the parallelogram.

Parallelogram is the closed shaped quadrilateral which has opposite site equal and the opposite angle are equal.

As in the given figure the angle T and angle R is the opposite angle. Thus angle T and angle R will be equal to the each other. Thus,

[tex]\angle T= \angle R[/tex]

Put the values of the angle in the above equation. Thus,

[tex]40x+2=122[/tex]

[tex]40x=122-2[/tex]

[tex]40x=120[/tex]

[tex]x=\dfrac{120}{40}[/tex]

[tex]x=3[/tex]

Hence the value of the x  is 3.

Answer:

 x=0 and y=2

Step-by-step explanation:

We have been given system of equations:

2x+5y=10     (1)

And 2x+3y=6     (2)

Subtract equation (2) from(1) we get:

2y=4

y=2

Now, substitute y=2 in equation(2) we get:

2x+3(2)=6

2x+6=6

2x=0

x=0

Hence, x=0 and y=2

Answer: 10

Plug in the given x values and see which result is the largest

Plug in x = 0 ---> x^2+1 = 0^2 + 1 = 1

Plug in x = 1 ----> x^2 + 1 = 1^2 + 1 = 2

Plug in x = 2 ----> x^2 + 1 = 2^2 + 1 = 5

Plug in x = 3 ---> x^2 + 1 = 3^2 + 1 = 10

The range is therefore {1, 2, 5, 10} which is just the set of possible outputs.

We see that y = f(x) = 10 is the largest output of the range if the domain is restricted to the set {0, 1, 2, 3}

So 954 out of 1000 would be nine hundred fifty-four thousandths

Answer:

B.  0.33

Step-by-step explanation:

The probability will be given by the amount of space in the target area, blue, compared to the total amount of space, the red square.

The size of the blue square is 64 and the size of the red square is 196; this gives us a probability of

64/196 = 16/49 = 0.3265 ≈ 0.33.

The required probability that a dart will land in the blue region is 0.33. Option B is correct.

Given that,
A target is made of a blue square inside of a red square. The blue square has an area of 64 square units, and the red square has an area of 196 square units.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total sample space = 196
Total favorable space = 64
The probability that a dart will land in the blue region is given as.
probability = 64 / 196 ≈ 0.33

Thus, the required probability that a dart will land in the blue region is 0.33. Option B is correct.

Answer:

3⋅(5⋅x)

5⋅(x⋅3)

15x

Step-by-step explanation:

As the values are inside the brackets, it does not matter what side the (x3) is on, so 3⋅(5⋅x) is equivalent.

Multiplying the contents of the brackets in the third one (x * 3) by 5 gives the same value as 3 * (x * 5) so 5⋅(x⋅3) is also equivalent.

On multiplying the brackets out:

5 * x = 5x

5x * 3 = 15x

So 15x is also equivalent.

Step-by-step explanation:

By calculating 2/3 of 600, we find that 400 seeds sprouted, which means 200 seeds did not sprout.

To determine how many seeds did not sprout, we start by calculating the number of seeds that did sprout. Given that 2/3 of the 600 seeds sprouted, we multiply 600 by 2/3:

600 × (2/3) = 400

So, 400 seeds sprouted. Next, we subtract this number from the total number of seeds to find out how many did not sprout:

600 - 400 = 200 seeds

Therefore, 200 seeds did not sprout.

Answer:

y = 8/5x - 9

Step-by-step explanation:

That would be your equation.

Final answer:

The question pertains to finding the equation of a straight line with a given slope of 8/5 and a y-intercept of (0,-9), which can be represented in slope-intercept form as y = (8/5)x - 9.

Explanation:

The question involves constructing the equation of a line with a given slope and y-intercept.

To find the equation of a line, we use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope and b is the y-intercept.

Given the slope of 8/5 and a y-intercept of (0,-9), the equation of the line would be y = (8/5)x - 9.

The slope tells us that for every increase of 5 units in the horizontal direction (-axis), the line rises 8 units in the vertical direction (-axis). Meanwhile, the y-intercept indicates that the line crosses the y-axis at -9.

Given that,

A third-grade gym class has 54 students

The gym teacher divides them into 9 groups

Then divides each group into 2 teams

The number of students in each team = ?

Number of students in a group =   54/9

Answer:

Examples of linear functions would be relationships that represent a constant rate of change, such as 20 miles per gallon of gas.  Exponential functions would be relationships that represent a growth or decay the increases or decreases by an exponential amount, such as a bacterial growth that doubles each hour.  Examples of situations that would be neither linear or exponential would be absolute value functions or quadratic functions.

Step-by-step explanation:

Situations, or relationships between data, that can be modeled with a linear function must show a constant increase or decrease in rate.  For example, we could control the rate of temperature in a water bath by two degrees every ten minutes.  For exponential functions, these can be modeled in situations where there is a significant growth or decay of a material.  For instance, the radioactivity of an element will decrease by one-half every year.  This would represent an exponential decay.  For other types of situations, such as changes in body temperature (absolute value) or the speed of a kayaker (quadratic), these would not be modeled using either linear or exponential functions.

A linear function can model constant rate of change, exponential function can model constant growth or decay, and some situations do not fit into these mathematical models.

A linear function can model situations where there is a constant rate of change between two variables. For example, if the cost of a movie ticket increases by $2 for every additional hour of the movie, you can represent this relationship with a linear function.

An exponential function can model situations where there is constant growth or decay. For example, if the value of an investment doubles every year, you can represent this relationship with an exponential function.

There are situations that cannot be modeled with either a linear or exponential function. For example, unpredictable events or situations with multiple complex factors may not fit into these mathematical models.

Answer:

6.33... and 0.333...

Step-by-step explanation:

The quadratic formula is

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex].

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions.  Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}[/tex]

We will now solve for the plus and the minus.

The plus,,,

[tex]x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3[/tex]

and the minus...

[tex]x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...[/tex]
