Given the functions, fx) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the domain
restriction
(f/g)(x)

Answers

Answer:

Step-by-step explanation:

f(x)/g(x)=(6x+2)/(x-7)

The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.

So the domain is all real numbers except 7. In interval notation the domain is

x=(-oo, 7),(7, +oo)

Holly missed 7 of 183 school days this year. Approximately what percent of school days was Holly in attendance? OA. 26% B. 96% OC. 74% Reset Submit 7 of 10 Answered Session Tuner: 30-32 Session Score:​

Answers

Answer:

B: 96%

Step-by-step explanation:

Since 7 out of 100 is 7% (7÷100=0.07)

then 7÷183=0.038 or 0.04. So 4% of the days she was absent. 100%-4% is 96% so holly was in attendance for 96% of the days.

Since ∆ABC is congruent to ∆TUV, then:

m<U = m<B

Therefore:

Collect like terms

4y - 3y = 16 + 2

y = 18

✔️m<U = 4y - 16

Substitute the value of y:

m<U = 4*18 - 16 = 56°

1) At a diner, the cost for a specialty waffle and a hashbrown is $9.50. The cost for 2 specialty
waffles and 3 hashbrowns is $20.50. Determine the cost of a waffle and the cost of a hashbrown.



Answers

9514 1404 393

Answer:

waffle $8hashbrowns $1.50

Step-by-step explanation:

Using w and h for the costs of a waffle and hashbrowns, respectively, we can write the equations for the purchase amounts as ...

  w + h = 9.50

  2w + 3h = 20.50

Subtracting twice the first equation from the second gives ...

  (2w +3h) -2(w +h) = (20.50) -2(9.50)

  h = 1.50 . . . . . . simplify

  w = 9.50 -h = 8.00 . . . . . find w using the first equation

The cost of a waffle is $8.00; the cost of hashbrowns is $1.50.

You can't add them together because they don't have the same denominator so you multiply 2/3 by 4/4 and 3/4 by 3/3. The result is 8/12 and 9/12, you add it together to get 17/12. 17/12 is an improper fraction, if you want you can change it into a mixed fraction which is 1 5/12.

b) lemon juice has four times more hydrogen ions than milk.

c) lemon juice has about 10,000 times more hydrogen ions than milk.

d) lemon juice is about three times more hydrogen ions than lemon juice. ​

Answers

Answer:

The correct answer is A. Milk has about 1/3 as many hydrogen ions as lemon juice.

Step-by-step explanation:

Given that the PH indicates the amount of hydrogen ions present in a certain solution, and that, the higher the PH, the lower this amount will be, if the milk has a PH of 6 and the lemon has a PH of 2, to calculate the respect correct, the following calculation must be performed:

2/6 = 1/3 = 0.333

Therefore, milk has about 1/3 as many hydrogen ions as lemon juice.
