If the point (2K-3, K+2) lies on the graph of the equation 2x+y+14=0, find the value of k.?​

Answers

Answer 1

Answer:

k = -2

Step-by-step explanation:

Substitute 2k-3 for x and k+2 for 2

2x + y + 14 =0

2(2k-3) + (k + 2) + 14 = 0

4k - 6 + k + 2 + 14 = 0

4k + k - 6 + 2 + 14 = 0

5k + 10 = 0

5k + 10 - 10 = 0 - 10

5k = -10

[tex]\frac{5k}{5} = \frac{-10}{5}[/tex]

k = -2

Answer:

  f(x) = x³ -4x² -5x +20

Step-by-step explanation:

If the function is to have rational coefficients, each complex or irrational square root must have a matching conjugate. That is, both -√5 and +√5 must be roots. If there is a root p, then there is a factor (x -p). The factored form of the minimal polynomial is ...

  f(x) = (x -4)(x +√5)(x -√5)

  = (x -4)(x² -5)

There was a sample of 350 milligrams of a radioactive substance to start a study. since then, the sample has decayed by 7.3% each year. let t be the number of years since the start of the study. let y be the mass of the sample in milligrams. write an exponential function showing the relationship between y and t .

Answers

Answer:

y = 350*0.927^t

Step-by-step explanation:

Initial amount = 350 mgDecay = 7.3% per year or 0.073Time = t yearsFinal mass = y

The equation:

y = 350*(1 - 0.073)^t = 350*0.927^t

Answer:

B) y = 5x + 29

Step-by-step explanation:

A parallel line means it will have the same slope.

    So far our equation looks like this: y = 5x + b

We will now plug in (-6, -1) to solve for b.

    y = 5x + b

    (-1) = 5(-6) + b

    -1 = -30 + b

    29 = b

So our answer is y = 5x + 29

    This is option B

Mr. Ryan is buying a home for $250,000. He is making a 20% down payment and
financing the rest with a 25-year loan at 5% interest. What will his monthly payment
be?

Answers

Since 20% down payment, we will find the 20% of that $250,000.

10% is $25,000, now times by 2 would be 20% which is $50,000.

Now $250,000 - $50,000 = $200,000 which would be rest of the non-payed payment.

We will divide $200,000 with the 25 year loan. $200,000/25 = $8,000

There is also the 5% interest.

1% of $8,000 is $80 and times that by 5 would be 5% which is $400.

$8,000 + $400 = $8,400.

Since it is monthly, we will divide $8,400 by 12 months. $8,400/12 = $700.

The monthly payment would be $700.

(I hope this is correct.)

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

The term PEMDAS describes the sequence in which arithmetic operations must be carried out in an equation.

It is given that the length of the toy model car is 15 inches and the actual car is 20 feet

As we know 1 foot consists of 12 inches as a result  20 feet has 240 inches.

The scale distance between the toy model and the actual car is the difference between the actual length and the model length.

Scale distance = 240 inches - 15 inches

Scale distance =225 inches

Thus, if I built a toy model of my car for the given condition the scale distance between the toy model and the actual car will be 225 inches.
