a(q-8)=23
solve for q
help appreciated!
Answer:
q= (23+8a)/a
Step-by-step explanation:
a(q-8)=23
or, aq-8a = 23
or, aq = 23+8a
or, q = (23+8a)/a
(I’m not sure if the A is part of the question or if A is what question you’re answering but I’ll work o for both)
A(q - 8) = 23
Multiply everything inside the brackets by A:
aq- 8a = 23
Divide both sides by a to isolate q - 8a:
q - 8a = 23 / a
Add 8a to both sides to isolate q:
q = 23 + 8a² / a
Without the A:
q - 8 = 23
Add 8 to both sides to isolate q:
q = 31

What is the degree of the polynomial f(x)=5x^4 -7x^3-12x^2+4x-2?
write any three rational numbers between -2 and 0.
please answer fast!!!!!!!
3 rational numbers between -2 and 0 are -1.5, -1, and -0.5.
Rational numbers can be either positive or negative, and can even be decimals. Therefore, -1.5, -1 and -0.5 are all rational numbers.

The function y = 2x + 8 represents the cost y (in dollars) of a large pizza with x toppings, where x
is equal to 0, 1, 2, or 3.
Identify the independent and dependent variables, the domain, and the range.
Answer:
0 ,1,2,3,/ is range/ y is the independent varibal/ x is the dependent varible/ /the equation is the domain
Step-by-step explanation:
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.
What is a function?A function is defined as a relation between a set of inputs having one output each.
Inputs are called the domain and independent variables.
Outputs are called the range and dependent variables.
We have,
y = 2x + 8
y = cost of pizza in dollar
x = toppings on pizza
x = 0, 1, 2, or 3
y = 2 x 0 + 8 = 8
y = 2 x 1 + 8 = 2 + 8 = 10
y = 2 x 2 + 8 = 4 + 8 = 12
y = 2 x 3 + 8 = 6 + 8 = 14
Thus,
The domain and independent variables are 0, 1, 2, and 3.
The range and dependent variables are 8, 10, 12, and 14.

Can someone help my sis on these questions? I dont remember how to do these things (part 1)
Answer:
Read below for each answer! (^-^)
Step-by-step explanation:
1: You got the first one right. The explanation does explain why but think about 0 as the surface of the water to better understand.
2: -3; it is between 2 and 4 with only one line through it meaning that it is -3.
3: 7. That's the greatest number both can divide into it.
4: The last one. Any positive number is greater than a negative one and peanut butter's freezing point is positive while the other one's is not.
5: You got it right again! -(-1) has two negatives. Two negatives (mostly) make a positive. So positive 1! Now describe that on a number line.
Hope this helps!
the number y of calories burned after x hours of rock climbing is represented by the linear function y=650x find the domain , is the domain descents or continuous? explain
Answer:
The domain is discrete
Step-by-step explanation:
Given
[tex]y = 650x[/tex]
Required
What type of domain is it?
Based on the given options, the domain is continuous.
From the question, we understand that x represents the hours spent in climbing the rock.
The climber can decide to climb for 1 hour, 2 hours, ½ hour, ⅓ hour, ¼ hour, etc..
A domain is said to be discrete if it can only take integers (i.e. whole numbers), if otherwise, it is continuous;
So, since x is not limited to only whole numbers, then we can conclude that the domain of x is continuous
Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?
a. b = -16
b. b = -8
c. b = 16
d. b = 32
Answer:
d
Step-by-step explanation:
The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.

Answer:
n = -1
Step-by-step explanation:
First distribute the -4
15-4n+8=27
Combine 8 & 15
-4n+23=27
Subtract 23 from each side
-4n=4
Divide each side by -4
n=-1
Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!
Answer:
n= -1
Step-by-step explanation:
15-4(n-2)=27 do the () first
15-4n+8=27 subtract 15 and 8 from both sides to get the -4n alone
-4n= 4 divide by -4
n= -1

The system of equations below has exactly one (x, y) pair for its solution.
4x+6y=244x+6y=24
2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.

Solve for z:
14=z-(-12)
z=___
Answer:
z=2
Step-by-step explanation:
14=z+12
2=z
Answer: The answer is z=2.
Step-by-step explanation: Step 1. Simplify the both sides of the equation: [tex]14=z+12[/tex].
Step 2. I flipped the equation that looks like this: [tex]z+12=14[/tex].
Last but not least is step 3. Subtract 12 from the both sides: [tex]z+12-12=14-12[/tex]; ∴, your answer should be z=2, I hoped this helps, Happy New Year, and mark me as brainliest. :D
