How do I factor x^2+7×+6

Answers

Answer 1

Answer: $x^2+7x+6\n\n7x=6x+1x\n\n6=6\cdot1\n\nx^2+7x+6=(x+6)(x+1)$

Answer 2

Answer: To factor the equation, you need to convert it to the form (x+a)(x+b) and find out what a and b are.
When you multiply (x+a)(x+b), you get x² + (a+b)x + ab.
With the expression x² + 7x + 6, we know that a+b is equal to 7 and a times b is equal to 6.
The only two numbers that add to 7 and multiply to 6 are 1 and 6, leaving us with:
(x+6)(x+1)

An electrician charges a flat fee plus an hourly rate for a service call. She charges a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday. How much should she charge for a 2-hour service call?

Answers

When the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

Electricians charge a fixed rate + an hourly rate. The charges are a total of $94 for a 3-hour service call on Monday and $130 for a 5-hour service call on Tuesday.

How to solve the linear equation?

A linear equation is a one-degree equation. The equation includes the variable of the highest power one. The standard form of an equation is Ax + B = 0, where x is the variable, A is the coefficient and B is a constant.

To solve the linear equation we need to find the unknown variable which satisfied the given linear equation.

Electricians charge a fixed rate + an hourly rate

If he charges, $94 for a 3-hour call on Monday and $130 for a 5-hour call on Tuesday then charging for 2 extra hours is the difference between the two amounts.

130 - 94 = $36

for an hourly rate, it will be $18

For the fixed traveling charge, we will subtract the 3-hour rate from a fixed rate of $94 - 3 × $18 = $40

So, for x hour call the equation will be, 40 + 18x

for 2 hour service, the charges would be 40 + 18 × 2 = $76

Therefore, when the charge for 3 hours is $94 on Monday and $130 for 5- hour service on Tuesday would charge for 2-hour call service is $76.

First you need to find what the hourly rate is and what the flat rate is. The hourly rate is $18 and the flat rate is $40. Then you add $40+ (18x). Substitute 2 in for x for the hours and get $76.

A hospital employs a total of 77n nurses and doctors. The ratio of nurses to doctors is 9:2. How many nurses are employed at the hospital? How many doctors are employed at the hospital.

Answers

Answer:

number of nurses employed at the hospital is 9x = 9 * (7n/9) = 7n, and the number of doctors is 2x = 2 * (7n/9) = (14n/9).

Step-by-step explanation:

Given the ratio of nurses to doctors is 9:2, we can express this as:

Number of nurses (9x) : Number of doctors (2x)

Now, you've mentioned that the total number of nurses and doctors employed at the hospital is 77n. So, we can set up an equation:

9x + 2x = 77n

Combine like terms:

11x = 77n

Now, to find the number of nurses (9x) and the number of doctors (2x), we need to divide both sides by 11:

9x = (77n) / 11

9x = 7n

Now, we can solve for x:

x = (7n) / 9

So, the number of nurses employed at the hospital is 9x = 9 * (7n/9) = 7n, and the number of doctors is 2x = 2 * (7n/9) = (14n/9).

In summary:

- Number of nurses = 7n

- Number of doctors = (14n/9)
