Answer:
C. (b-c)(a+b)
Step-by-step explanation:
This i s because there is a positive b squared in the expanded equation so both brackets had to have had a positive b term in them.

Find an expression which represents the difference when (-8x-8y) is subtracted from (6x+y) in simplest terms.
The expression that represents the difference between the two algebraic expressions given is: 14x + 9y.
What is the Difference of Algebraic Expressions?The difference between two algebraic expressions is simply gotten by subtract one from the other.
Thus, find the difference between the two algebraic expressions, (6x+y) and (-8x-8y).
(6x+y) - (-8x-8y)

For f(x)=2x+1 and g(x)=x^2-7 find (f-g)(x)
Answer:
-x² + 2x + 8
Step-by-step explanation:
Essentially we need to subtract g(x) from f(x):
(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)
Distribute the negative:
(2x + 1) - x² - (-7) = (2x + 1) - x² + 7
Combine like terms:
2x + 1 - x² + 7
-x² + 2x + 8
Thus, the answer is -x² + 2x + 8.

Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).
[tex](f/g)(x)=\frac{3x+2}{3x-5}[/tex]
To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.

Additional comments
You can keep a product the same if you divide one factor by 10 and multiply the other factor by 10:
8.91×10² = (8.91/10)(10×10²) = 0.891×10³
I like to "pre-scale" the numbers in a problem like this so that the product comes out in scientific notation with no adjustment needed. That is, the product of the two mantissas is a number between 1 and 10.
Here, you can tell the product of 8.91 and 3.3 will be more than 24, so scaling will be necessary. It is convenient to scale the larger mantissa to be less than 1 so the product comes out less than 10. That is why we made it 0.891×10³.

12 more than quotient of a number k and 5
Answer:
(k/5)+12 represents the question described
The required equation is 12 + k/5.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given statement is,
12 more than quotient of a number k and 5
Converting them into numerical form,
quotient of a number k and 5 = k/5
Therefore 12 more than quotient of a number k and 5 is written as,
12 + k/5
this is the required equation for the given statement.
Thus, the required equation is 12 + k/5.

(If someone answers fast i will mark you brainliest ) Which ordered pair would form a proportional relationship with the point graphed below? (10, -20) (-30, 20) (-10, 5) (35, -20)
Answer:
(-10, 5)
Step-by-step explanation:
(10, -20), (-30, 20), (35, -20) ⇒ these points are not on the line, so they don't form a proportional relationship with the graph.
(-10, 5) ⇒ this point is on the line, so it forms a proportional relationship with the graph.

Xian and his cousin Kai both collect stamps. Xian has 52 stamps, and Kai has 72 stamps. The boys recently
joined different stamp-collecting clubs. Xian's club will send him 12 new stamps per month. Kai's club will
send him 8 new stamps per month. After how many months will Xian and Kai have the same number of
stamps? How many stamps will each have?
After
months Xian and his cousin will have
stamps each.
Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.
Would appreciate if you could give brainiest have a great day
Answer:

Step-by-step explanation:
