What two numbers have a sum of -9 and a product of 20 ?

Answer:

f(x-4) = x²-8x + 17

f(x-4)-f(-4) = x²-8x

Step-by-step explanation:

Given the function:

f(x) = x^2+1

f(x-4) = (x-4)^2+1

f(x-4 ) = x² - 8x + 16 + 1

f(x-4) = x²-8x + 17

For f(x-4)-f(-4)

f(-4) = (-4)²+1

f(-4) = 16+1

f(-4) = 17

f(x-4)-f(-4) = x²-8x + 17 - 17

f(x-4)-f(-4) = x²-8x

Answer:

x = m + 3b

Step-by-step explanation:

add 3b to each side

x = m + 3b

Answer:

x=m+3b

Step-by-step explanation:

Hi there!

Our goal to make x the subject of the formula is to isolate x on one side and have everything else on the other side

here's the given formula:

m=x-3b

-3b is on the same side as x, which we don't want

add 3b to both sides (-3b+3b=0)

m=x-3b

+3b +3b

________

m+3b=x

since x is now the subject of the formula, we're done

Answer:

Rounded: $478.06

Step-by-step explanation:

Set up an equation:

Variable x = original price

62/100 = 296.40/x

Cross multiply

62 × x = 100 × 296.40

62x = 29,640

Divide both sides by 62:

x = 478.064516....

Round to nearest cent (hundredths place):

x = 478.06

Check your work (using the rounded estimate will be close to $296.40 but not exact because it is rounded; once you round your answer and it should match):

478.06 × 62%

Convert the percentage into a decimal:

478.06 × 0.62

296.3972

Round to the nearest cent (hundredths place):

296.40

Answer:

Ed's answer of [tex]\frac{3}{8}[/tex] is correct because he divided [tex]\frac{1}{4}[/tex] by [tex]\frac{2}{3}[/tex] to get his answer.

Step-by-step explanation:

To solve for m in [tex]\frac{2}{3}m=\frac{1}{4}[/tex] you want to isolate m by dividing by [tex]\frac{2}{3}[/tex] on both sides, therefore he divided [tex]\frac{1}{4}[/tex] by [tex]\frac{2}{3}[/tex] to get his answer of [tex]\frac{3}{8}[/tex], and his answer is correct.

Answer:

The answer is 4 \sqrt{7}.

Step-by-step explanation:

The formula is a\sqrt{x} + b\sqrt{x} = (a+b)\sqrt{x}, but if you don't understand it, here's an easier way to think about it.

You can think of \sqrt{7} as x (or any other variable). Now, the equation is 3x + x. If you've ever done algebra, (you probably have if square roots popped up on your homework) you know that this equals to 4x. Now, replace the x with \sqrt{7}, because we already decided that those two were equal. Therefore, the answer is

4 \sqrt{7}.

Answer:

Option D, x² + 4x - 21

Step-by-step explanation:

Using FOIL;

x * x = x²

x * (-3) = -3x

7 * x = 7x

7 * (-3) = -21

Therefore; x² + (-3x) + 7x - 21

=> If simplified:

=> x² + 4x - 21

Answer:

$1,955.86

Step-by-step explanation:

We have to use the MS Excel to solve this question

PV = -300000

FV = 0    

I = 6.8%/12 = 0.5667%    

N = 30*12 = 360

Monthly payment = PMT(-PV, FV, I, N)

Monthly payment = PMT(-300,000, 0, 0.5667%, 360)

Monthly payment = $1955.8555499

Monthly payment = $1,955.86

So, her monthly payment is $1,955.86.

Step-by-step explanation:

3. 840 + 168 -> 1008

Answer:

x = 2.2

Step-by-step explanation:

2(x+4)+6 = 12x-8

Use distribution property

2x+8+6 = 12x-8

Combine like terms

2x+14 = 12x-8

Subtract 14 from both sides

2x = 12x-22

Subtract 12x from both sides

-10x = -22

Divide both sides by negative 10

x = 2.2 or x = 11/5 in fractions.

Answer:

A Hermitian matrix is a matrix that is equal to its conjugate transpose. This generalizes the concept of a "symmetric matrix", since every real symmetric matrix is Hermitian.

Answer:

p = 0.259264214

Step-by-step explanation:

26 - 7 = 19 with good brakes

Probability of picking 4 with good brakes

p = 19/26 * 18/25 * 17/24 * 16/23

p = 0.259264214

The probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.

To calculate the probability that all the randomly chosen cars have good brakes, we need to consider the number of cars with good brakes and the total number of cars.

Total number of cars assembled: 26

Number of cars with bad brakes: 7

To calculate the probability, we can use the concept of combinations.

The number of ways to select 4 cars out of the remaining 26-7 = 19 cars with good brakes is given by the combination formula:

C(n, r) = n! / (r! * (n-r)!)

where n is the total number of cars with good brakes and r is the number of cars to be randomly selected.

In this case, n = 19 and r = 4.

The total number of ways to select 4 cars from the total pool of 26 cars is given by the combination formula:

C(26, 4) = 26! / (4! * (26-4)!)

Now, we calculate the probability that all the randomly chosen cars have good brakes:

Probability = (Number of favorable outcomes) / (Number of total outcomes)

Number of favorable outcomes = C(19, 4)

Number of total outcomes = C(26, 4)

Probability = C(19, 4) / C(26, 4)

Using a calculator, we can compute these combinations and evaluate the probability:

Probability ≈ 0.169

Therefore, the probability that all the randomly chosen cars have good brakes is approximately 0.169 or 16.9%.
