Answer:
X=-5
X=-7
Step-by-step explanation:
-12x+(-4)=56
rewrite the equation to -12x-4=56
add 4 to both sides
-12x=60
Divide by -12 on both sides
x=-5
-2.1x+(-3.9)=10.8
-2.1x-3.9=10.8
-2.1x=14.7
divide by -2.1 on both sides
x=-7

Answer:
Domain: -5 ≤ x < 1
Range: -4 ≤ x < 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that are outputted by function f(x).
We see from the graph that our x-values span from -5 to 1. Since -5 is closed dot, it is included in the domain, but since 1 is open dot, it is not included in the domain:
[-5, 1) or -5 ≤ x < 1
We see from the graph that our y-values span from -4 to 7. Since -4 is closed dot, it is included in the range, but since 7 is open dot, it is not included in the range:
[-4, 7) or -4 ≤ x < 7
Aaden wants to get a subscription to a library. there are two subscription options one of which charges a fixed 96 dollar annual fee and the other which charges 3 dollars per book he borrows.
what does point Q represent in this context?
Answer:
The data we have is:
Library A charges $96 per year.
Library B charges $3 per book he borrows.
Let's find the number of books X that he needs to borrow in order to spend the same amount in each library:
$3*X = $96
X = 96/3 = 32.
This means that if Aaden borrows 32 books per year, is the same for him if he chooses library A or B.
If he borrows more than 32 books per year, library A will be cheaper. (if he borrows 33 books, library B costs 33*$3 = $99, which is larger than the $96 of library A)
If he borrows less than 32 books per year, library B will be cheaper. (if he borrows 31 books library B costs $3*31 = $93, which is cheaper than the$96 of library A)
Step-by-step explanation:
Answer:
A number of books and their cost that is not possible with either subscription
Step-by-step explanation:
Point S is neither on line aaa nor line b, so it represents a number of books and a cost that is different from the combinations possible with either subscription.

During the month of December a bus company decides to only sell daily passes. They charge 3$ dollars per pass. Describe the domain and range of the scenario above
Using function concepts, it is found that:
The domain of the scenario is: {0, 1, 2, 3, 4,...}.
The range of the scenario is: {0, 3, 6, 9, 12,...}
The domain of a function is the set that contains all possible input values.
In this problem, it is the number of passes sold per day, thus, the domain of the function is: {0, 1, 2, 3, 4,...}.The range of a function is the set that contains all possible output values.
In this problem, it is the amount earned when x passes are sold, considering that each pass is sold for $3, the range of the function is: {0, 3, 6, 9, ...}A similar problem is given at https://brainly.com/question/24742551

7n + 5 − 9n = 8 − 2n − 3
Answer:
7n + 5 − 9n = 8 − 2n − 3 = true
-2 n + 5 = 5 - 2 n = true
Step-by-step explanation:
Left-hand side:
Simplify the following:
7 n - 9 n + 5
Grouping like terms, 7 n - 9 n + 5 = 5 + (7 n - 9 n):
5 + (7 n - 9 n)
7 n - 9 n = -2 n:
Answer: -2 n + 5
____________________________
Right-hand side:
Simplify the following:
-2 n - 3 + 8
Grouping like terms, -2 n - 3 + 8 = (8 - 3) - 2 n:
(8 - 3) - 2 n
8 - 3 = 5:

I need help with this question
Answer: 5x - 1 = -6
Step-by-Step Explanation:
We have this diagram here showing numbers and symbols. Just a remainder, "X" is a variable which can be found through and equation of Algebra. Alright, so we have 5 boxes with the symbol "X". Alright, that's a start, so we have 5x as a start of the equation. We have -1 on the same side as well.
Alright, so on the other side- we have Six symbols of "-1".
That concludes to... -6. Alright, notice how all of the symbols are on a Scale, so we can heavily imply that the "=" symbol will take place between the two sets of symbols. Alright, combining them we get.. 5x - 1 = -6.

Answer: q³⁰
Explanation:
First just solve the first part using the exponent rules
p²q⁵ becomes 1/p-⁸q-²⁰ then we flip the fraction so the exponents become positive. Now we have p⁸q²⁰.
Before multiplying the other equation, we must simplify. p-⁴q⁵ becomes 1/p⁴q-⁵ and since it's the exponents being raised to a power we simply multiply the inner exponents times the outer exponent which yields 1/p⁸q-¹⁰. We must make q-¹⁰ positive so we will then bring it to the numerator of the fraction which gives us: q¹⁰/p⁸.
Multiply q¹⁰/p⁸ * p⁸q²⁰/1 = p⁸q³⁰/p⁸ divide the p exponents by each other which yields 0 since when u divide exponents you just subtract them so 8 - 8 = 0. Your answer is now q³⁰/1 or just q³⁰

Min has dozen blueberry muffins and 1 dozen pumpkin muffins. How many more blueberry muffins than pumpkin muffins does Min have? Enter your answer as a fraction in simplest form by filling in the boxes,
Answer:
7/12
Step-by-step explanation
We have both of the values of the dozen of doughnuts 5/6 of a dozen blueberry and 1/4 dozen pumpkin. In order to determine how many more blueberry muffins Min has, we have to set the denominators to be the same number. To do this we need a common denominator. The least common denominator between 6 and 4 is 12. We multiply the top and bottom of the fraction 5/6 by 2 to get 10/12. We then multiply 1/4 by 3 to get 3/12. 10-3 = 7, therefore Min has 7/12 more blueberry muffins
Answer:
7/12
Step-by-step explanation:
because when you subtract you have to find the LCD or LCM and 12 is the common multiple next you have to find equivalent fractions to 5/6 and 1/4 and you get 5/6=10/12, 1/4=3/12. 10/12-3/12 is 7/12
