Answer:

y=6/5x+11

Step-by-step explanation:

Perpendicular lines have the opposite sign and reciprocal of the original line. Since the y-intercept is 11 we know that it is 6/5x+11

Answer:

4x+7y=1782 i beleive it would be

Step-by-step explanation:

Answer:

 x + y = 294   (1)

4x + 7 y = 1782 (2)

(1) => x=294-y  replace x into (2)

=> 4( 294-y ) + 7y = 1782 => y = 606/3 =202

=> x = 294 - 202 = 92

So : x = 92 and y = 202

Answer:

its sleet or snow

Step-by-step explanation:

its d or c

The air temperature is below freezing in and below the clouds.The  most likely form of precipitation is sleet or snow.

Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.

Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.

Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

Answer: x= -2 and y= -3.

Step-by-step explanation:

The given system of equations :

4x-7y=13    ...(i)

4x + 7y = -29​     ....(ii)

By Elimination method, Eliminating (ii) from (i) , we get

[tex]-7y-7y=13-(-29)\\\\\Rightarrow\ -14y=13+29\\\\\Rightarrow\ -14y=42\\\\\Rightarrow\ y=\dfrac{42}{-14}\\\\\Rightarrow\ y=-3[/tex]

Now, Adding (i) and (ii), we get

[tex]8x=-16\\\\\Rightarrow\ x=\dfrac{-16}{8}\\\\\Rightarrow\ x=-2[/tex]

Hence, the solution is : x= -2 and y= -3.

Delta Math Solution

It would take 2.92 years for the value of the account to reach $6,880.

Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.

Maya deposited $5,000 in an account with a 3.9% compounded annual interest rate.

To solve this problem, we can use the formula for continuously compounded interest: [tex]A = Pe^{rt}[/tex], where A is the final amount of the investment, P is the initial amount of the investment, r is the interest rate, and t is the time in years.

We can rearrange the formula to solve for t: t = (ln(A/P)) / r

Plugging in the values from the problem, we get: t = (ln(6880/5000)) / (3.9/100) = 2.92 years

Rounded to the nearest tenth of a year, this is approximately 2.9 years.

The highest common factor is 7(3x+1)

Step-by-step explanation:

Here, we want to find the highest common factor of both expressions

As we can see, the highest common factor of 7 and 14 is 7

Now, we have the second expression which is (3x+1)

No matter what the first expression is raised to, it still stands that the highest common factor we shall have there is 3x+ 1 as concerns the term

Answer:

Slope = -4

Step-by-step explanation:

Given points are :

(-1,30) and (4, 10)

We need to find the slope of the line that passes through these points.

We know that, the formula for the slope of line is given by :

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

Put values in the above formula.

[tex]m=\dfrac{10-30}{4-(-1)}\\\\=\dfrac{-20}{5}\\\\=-4[/tex]

So, the slope of the line is -4.

The correct option for Kristen's population of interest would be "All students at her high school."

Here, we have,

The population of interest refers to the specific group of individuals that the researcher wants to draw conclusions about or make inferences regarding a particular research question.

In this case, Kristen is specifically interested in the opinions of students at her high school regarding the proposed new school hours.

Therefore, her population of interest is limited to the students within her own high school.

The other options mentioned such as "All members of the school board," "All teachers at her school,"

"All students in the school district,"

and "All high school students in the state" represent broader or different groups that are not the specific focus of Kristen's investigation.

Hence, in this case, it is concluded that the correct answer is "All students at her high school."

Answer:

Step-by-step explanation:

sure lizzie  

soo  elimination method just means we want to cancel out on of the variable by subtracting of add the entire equations to each other... there is another method but this one is pretty good to learn with.

system 1

2x + 2y = -2

3x - 2y = 12

since there is already an easy way to get rid of the y variable lets just add the two equations together, just add term by term

5x  + 0y = 10

if you notice .. just by making an imaginary column.. of each term.. you can just do that single piece by it self.... 2x + 3x = 5x   and 2y +(-2y) = 0  and -2 + 12 = 10  :)

so now I can rewrite our new equation

5x = 10    I can solve this one with my eyes closed  :D  (10/5 = 2 )

x =2   :P

now , since we know x  .. just plug in the known value of x into the 1st equations...  

2(2) +2y = -2

4 + 2y =-2

2y = -2-4

2y = -6

y = - 3   :) ( I had to keep my eyes open that time b/c there was a minus sign floating about and those are too easy to mess up on .. when you do.. don't worry everyone does )

so we know

x = 2  and y = -3  :)

I'll go a little faster on 2.. and I see 3 is good for you to practice on.. just ask later if you have questions on that one.

system 2

4x - 2y = -1

-4x + 4y = - 2

add them again to get rid of the x term

0x +2y = -3

y = - 3/2

plug in y

4x  - 2(-3/2) = -1

4x +3 = -1

4x = -1 - 3

4x = -4

x = -1  

they are being nice and making them easy to start out.. you try system 3

a + c  > b

b + c  > a

Answer:

14dimes and 5 nickels

Step-by-step explanation:

Tim have 14 dimes and 5 nickels.

In simple terms, the unitary method is used to find the price of a single unit from a given multiple.

Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that there are 19 nickels, let n=number of nickels.

The number of total coins subtracted by number of nickels will give us the number of dimes.

The Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)

Then we can substitute total as $1.65 and get the value of nickels by multiplying by 5cent

Since the value of the dimes is the value of nickels subtracted from the total, we can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.

5(n)=5(19)=95

(165-95)/10 =number of dimes

70/10 = 7dimes
