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.

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)
Open the bracket
6x + y + 8x + 8y
Combine like terms
14x + 9y
Therefore, the expression that represents the difference between the two algebraic expressions given is: 14x + 9y.

(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.

Sorry I also need help with this question
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.

Which operation has to be calculated first in this expression?
7 – (4 + 5)
Answer:
Addition
Step-by-step explanation:
You should add 4 and 5 first because of PEMDAS.
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Since 4+5 is in parentheses it should be done first.
Answer:
Addition
Step-by-step explanation:
This the answer because:
1) First, we have to know the Order of Operations
2) An easy way of remembering this is PEMDAS or GEMS
PEMDAS : Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction
GEMS : Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right), Addition and Subtraction (whichever one comes first from left to right)
3) In this expression, parenthesis would be first because that's what comes first in the order of operations
4) Inside the parenthesis is another expression where you need to add. Therefore, the answer is addition
Hope this helps!

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:
6 months
Step-by-step explanation:
56+ 12x = 80 + 8x
