Answer:
A
Step-by-step explanation:
We have the two functions:
[tex]f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\[/tex]
And we want to find:
[tex](f-g)(x)[/tex]
This is equivalent to:
[tex]=f(x)-g(x)[/tex]
Hence, by substitution:
[tex]=(3x^2-2x)-(9x^2-x+7)[/tex]
Distribute:
[tex]=(3x^2-2x)+(-9x^2+x-7)[/tex]
Rearrange:
[tex]=(3x^2-9x^2)+(-2x+x)+(-7)[/tex]
Combine like terms:
[tex]=-6x^2-x-7[/tex]
Hence, our answer is A.
Answer:
Step-by-step explanation:
3x^2 - 2x - 9x^2 + x - 7
-6x^2 - x - 7
answer is A
Write an equation to make the number "24" using all the numbers 5,4,2,2 and +, -, x and ÷.
Answer: See explanation
Step-by-step explanation:
We are given the numbers 5,4,2, and 2 and told to make an equation from it and get a final answer as 24. This will be:
= 5 × 4 + 2 + 2
= 20 + 2 + 2
= 24.
Since we have gotten a final answer of 24, the equation is solved.

7b. Find the value of y."
Your answer
This is a required question
Answer:
x = 36
y = 34
Step-by-step explanation:
✔️Sum of the interior angles of an n-sided polygon = (n - 2) × 180
Thus, the figure given is a hexagon with 6 sides.
Therefore, the sum of its interior angles = (6 - 2) × 180
= 4 × 180 = 720.
This means:
(5x) + (4x + 2) + (5x + 5) + (2x - 2) + (3x + 5) + (x - 10) = 720
Solve for x
5x + 4x + 2 + 5x + 5 + 2x - 2 + 3x + 5 + x - 10 = 720
Add like terms
20x = 720
Divide both sides by 20
x = 36
✔️(2y - 1) + (3x + 5) = 180 (angles on a straight line)
Plug in the value of x
2y - 1 + 3(36) + 5 = 180
2y - 1 + 108 + 5 = 180
Add like terms
2y + 112 = 180
Subtract 118 from each side
2y = 180 - 112
2y = 68
Divide both sides by 2
y = 68/2
y = 34

6 3/4 divided by 4 1/2
Answer:
1.5 (1 1/2)
Step-by-step explanation:
This is a method I personally like to use when you can change the fractions to decimals easily.
6 3/4= 6.75 (3/4= 0.75)
4 1/2= 4.5
6.75/4.5= 1.5
The result when the fraction [tex]6\frac{3}{4}[/tex] is divided by the fraction [tex]4\frac{1}{2}[/tex] is [tex]1\frac{1}{2}[/tex].
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, A fraction [tex]6\frac{3}{4}[/tex] is divided by the fraction [tex]4\frac{1}{2}[/tex].
Therefore, 27/4 is divided by 9/2 which is,
= (27/4)/(9/2).
= (27/4)×(2/9).
= 3/2 Or [tex]1\frac{1}{2}[/tex].

Question 9 options:
1) 20
2) 22
3) 24
Help
4) 28
Answer:
1) 20
Step-by-step explanation:
I drew a diagram of the triangle described below.
Note that we can use the Pythagorean Theorem, which states a^2 + b^2 = c^2 where a and b are the legs of the triangle and c is the hypotenuse.
We can apply this here. Since ST and TU are the legs and SU is the hypotenuse we can solve for SU:
SU = square root (12^2 + 16^2) = square root (400) = 20

A bike rental company charges a rental fee plus $8 per hour. If 6 hours costs $73, how much is the rental fee? Solve using an ALGEBRAIC EQUATION
Answer:
The rental fee is 25
Step-by-step explanation:
Total cost = rental fee plus cost per hours * number hours
t = f + 8*h where t = total cost, f = rental fee, h = hours
73 = f + 8*6
73 = f+ 48
Subtract 48 from each side
73 - 48 = f+48-48
25 = f
The rental fee is 25
