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

Which value of m satisfies the inequality 170 - 7m > 99?
Answer:
Step-by-step explanation:
170-7m > 99, subtract 170 from each side
-7m > -71, divide each side by -7 (and reverse sign because of division by negative)
m < 71/7 or
m < 10 1/7

Answer:
All those yeye snake me her first
Step-by-step explanation:
Since ∆ABC is congruent to ∆TUV, then:
m<U = m<B
Therefore:
4y - 16 = 3y + 2
Collect like terms
4y - 3y = 16 + 2
y = 18
✔️m<U = 4y - 16
Substitute the value of y:
m<U = 4*18 - 16 = 56°

2/3 + 3/4 =
Answer:
The answer will be 17/12
Step-by-step explanation:
Hope this Helped
Answer:
1 5/12 or 17/12
Step-by-step explanation:
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.
This is kinda easy so you shouldn't make it say college

lemon juice has a pH level of 2 but milk has a pH level of 6 how does the concentration of hydrogen ions in lemon juice compared to the concentration of hydrogen ions in milk?
a) milk has about 1/3 as many hydrogen ions as lemon juice
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.
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.

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.
9514 1404 393
Answer:
waffle $8hashbrowns $1.50Step-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.

Answer:
y=1/5x+2
Step-by-step explanation:
Slope intercept form is y=mx+b
m is the slope, and we're given the slope [tex]\frac{1}{5}[/tex], so plug that in:
y= (1/5)x+bThen we're given a point (10,4), in the format (x,y)
So 10 = x and 4 = y. Plug that in:
y=(1/5)x+b4=(1/5)(10)+bSolve for b:
4 = 10/5 + b4 = 2 + b2 = bNow we know that b=2, we can write slope intercept form:
y=1/5x+2Which expressions is equivalent to 50c - 25? (There is more than one answer)
5 (10c-10)
5 (10c - 5)
25 (2c-1)
5 (10-5)
Answer:
C
Step-by-step explanation:
25 (2c-1)
(25 x 2c) - (25 x 1)
50c - 25
