what is the slope of the line that goes through the points (7,3) and (-5,9)

Answer:

6.1

Step-by-step explanation:

If we are rounding at the 0 digit, we look at the next digit, which is 9

9 >= 5 so we need to round  the 0 up to 1

6.099 rounds to 6.1

Answer:

6.1 is your answer

Step-by-step explanation:

The underlined digit (the tenth place) is 0. Look at the number in the place value directly right to it (hundredth place). It is a 9. Because 9 is greater than 5, round up.

6.099 rounded to the nearest tenth place is 6.1

Answer:

x=9/4

Step-by-step explanation:

Performing the indicated multiplication, we get

2x - 3x + 4 = 3x - 5

Combining the x terms, we get -4x = -9, so that x = 9/4.

Answer:

The correct answer is D.

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.

Answer: Yoghes has $0.87

Step-by-step explanation: We want to know the total amount of money that Yogesh has:

each quarter values 25¢, a dime values 10¢, and a penny values 1¢

(or the values can be written as $0.25, $0.10 and $0.01 respectively)

Yogesh has 3 quarters, so this means he has: 3*$0.25 = $0.75

he has 1 dime, so in dimes, he has: $0.10

he has 2 pennies, so in pennies, he has: 2*$0.01 = $0.02

If we sum up the 3 amounts, we have:

Total = $0.75 + $0.10 + $0.02 = $0.87

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.

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:

0.4

Step-by-step explanation:

-1/5 = -2/10 = -0.2, -1/4 = -25/100 = -0.25

-0.25-(-1/5)+0.2+(-1/4) = -0.25+0.2+0.2+0.25 = -0.25+0.25+0.2+0.2 = 0.4

Answer:

nine hundred fifty-four thousandths

Step-by-step explanation:

If you mean written as in a form in words:

To the first decimal place means tenths because it is out of ten

To the second place, it's hundredths because 100 = 10^2

3rd is 1000, and so on

A fraction (as in two out of five), is expressed in words as "two fifths"

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

Step-by-step explanation:

We are given that

Suppose you have the probability of winning with a scratch -off lottery ticket,P(A) =[tex]\frac{1}{10}[/tex]

Probability:It is defined as the possibility of an event that is occurred or not.

It is obtained by dividing  the number of favourable cases with total number of cases.

The formula of finding out the probability of an event

P(E)=[tex]\frac{Number\;of\;favourable\; cases}{Total\;number\;of\;cases}[/tex]

We have to find the probability of winning 3 lottery

The probability of winning all three tickets,[tex]P(A AA)=P(A)\cdotP(A)\cdotP(A)[/tex]

Therefore, the probability of winning all 3 lottery =[tex]\frac{1}{10}\times \frac{1}{10}\times \frac{1}{10}[/tex]

The probability of winning all three tickets,P(A AA)=[tex]\frac{1}{1000}[/tex]

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

The number of students gym teacher has putted in each team is, 3

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

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

                                                    =    6 students

Then each group divided into two teams,

Number of students in each team = 6/2

                                                         = 3

Hence, the number of students is 3

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.

Answer:

If a car with a blowing horn is moving toward you, the pitch sounds higher than the actual emitted frequency.

Step-by-step explanation:

In figure,

        V= speed of wave

         U= speed of car

When car moving towards you, then

Car travels a distance in time T = VT

 Wave travels a distance in time T = UT

From figure,

                    change in wavelength (λ') = VT - UT= T(V-U)

Now,

        V = λ' f'         (f' →frequency observed by you)

         f' = V ÷ λ' = [tex]\frac{V}{T(V-U)}[/tex]

We know that

                      [tex]\frac{1}{T}[/tex] = f

Then,

        f' =  [tex]\frac{Vf}{V-U}[/tex]

        f' = [tex]\frac{f}{1-\frac{U}{V} }[/tex]

Hence, we can say that

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.

The equation of proportional situation is y = ax.

Therefore your answer is y = -2x + 14

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}

Answer:

f(x) + g(x) = 6x^2 + 28x + 36

Step-by-step explanation:

Thirty eight

You begin to solve this by writing it like this [just as you have it].

f(x) = x^2 + 5                    Now put g(x) where you see x

f(g(x)) = [g(x)]^2 + 5          Now substitute the right side of g(x) wherever you see g(x)

f(x - 4) = [x - 4]^2 + 5        Expand the brackets

f(x- 4) = x^2 - 8x + 16 + 5

f(x - 4) = x^2 - 8x + 21

=======================

Thirty Nine

f(x) = (x + 4)^2

g(x) = 5(x + 2)^2

Expand f(x)

f(x) = x^2 + 8x + 16

Expand g(x)

f(x) + g(x) = x^2 + 8x + 16 + 5x^2 + 20x + 20

f(x) + g(x) = 6x^2 + 28x + 36
