Given:
The parent function is
[tex]f(x)=8x+9[/tex]
To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then
[tex]g(x)=-f(x)[/tex]
Putting [tex]f(x)=8x+9[/tex], we get
[tex]g(x)=-(8x+9)[/tex]
[tex]g(x)=-8x-9[/tex]
The function after the reflection over the x-axis is [tex]g(x)=-8x-9[/tex].
Therefore, the correct option is B.

Step-by-step explanation:
[tex] \frac{1}{2}(\frac{3}{4}x + 10) - 2(x + 1) = [/tex]
[tex] = \frac{3}{8}x + 5 - 2x -2 [/tex]
[tex] = \frac{3}{8}x + 5 - \frac{16}{8}x - 2 [/tex]
[tex] = -\frac{13}{8}x + 3 [/tex]
[tex] = -1\frac{5}{8}x + 3 [/tex]

The theorem that applies to this question is the theorem of external angles. And it translates to:
[tex]11x +2 = 58 + 5x + 10[/tex]
Collect Like Terms
[tex]11x -5x = 58 + 10-2[/tex]
[tex]11x -5x = 66[/tex]
[tex]6x = 66[/tex]
Divide through by 6
[tex]\frac{6x}{6} = \frac{66}{6}[/tex]
[tex]x = \frac{66}{6}[/tex]
[tex]x = 11[/tex]
County Middle School is buying pizza for all of its students. Each pizza has 8 slices. Each student will receive 1 slice. There are 700 students at County Middle School. How many pizzas will the school need to buy?
Answer:
88 at least
Step-by-step explanation:
So, if you need to give each student a slice remainders round up to the nearest whole number. So first you simply divide 700/8 (Students/Pieces of pizza per slice) and get 87.5. Then you round up to 88 since you cannot buy half a pizza (that's weird). You will have 4 extra slices to feed the teachers btw.
I WILL MARK BRAINLIST! TIS IS SIMPLE PROBABILITY. A bag of game markers contain 4 red markers, 5 blue markers, 3 yellow markers, and 3 green markers. If Mario reaches into the bag and pulls out a game marker without looking, what is the probability he will NOT pull out a blue game marker?
A. 1/2
B. 1/3
C. 4.15
D. 2/3
Answer: D. 2/3
Step-by-step explanation:
There are 15 markers in total. Out of these 15 markers, there are 5 blue ones.
If Mark reaches into a bag to pull out one marker and hopes it is not blue, there would be a 2/3 probability as 2/3 of the markers are not blue.

125 is 30% of what number
Answer:
24
Step-by-step explanation:
Answer:
125 is 30% of the number 24, hope this helps
Step-by-step explanation:
We have, 125% × x = 30
or, 125/100 × x = 30
Multiplying both sides by 100 and dividing both sides by 125,
we have x = 30 × 100/125
So your answer is X=24

The minimum of the graph of a quadratic function is located at (-1, 2). The point (2, 20) is also on the parabola.
Which function represents the situation?
O f)=x+ 1 +2
O f)=(x-1 +2
O ) = 2(x+ 1) +2
O f)= 2(x- 1 +2
Answer:
he's right its c
Step-by-step explanation:
on edg
The correct function which represents the situation is,
⇒ f (x) = 2 (x + 1)² + 2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The minimum of the graph of a quadratic function is located at (-1, 2). The point (2, 20) is also on the parabola.
Now, By options;
The correct function has a point (2, 20).
Hence, It can satisfy the equation of parabola.
Now, By option 3;
⇒ f (x) = 2 (x + 1)² + 2
⇒ 20 = 2 (2 + 1)² + 2
⇒ 20 = 2 (9) + 2
⇒ 20 = 18 + 2
⇒ 20 = 20
Hence, The correct function which represents the situation is,
⇒ f (x) = 2 (x + 1)² + 2

Eugene had $24 to spend on three pencils.
After buying them he had $18. How
much did each pencil cost?
Answer:
$2
Step-by-step explanation:
First, we find the total he spent on the three pencils.
$24 - $18 = $6
He spent $6 on the 3 pencils.
Now we find how much each pencil cost.
$6/3 = $2
Answer: $2
Answer:
Each pencil cost 2$
First I did what he has to spend 24 then subtracted 18 from it what he had left that gave me 6. Next knew that he had bought three pencils so I did 6 divided by 3 and that left me with an answer of 2 so 2$

Answer:
Step-by-step explanation:
Circumference, C=2-3.14*r
diameter is 18, r=9
C=2*3.14*9=56.54 in^2
if radius is 8 m
C=2*3.14*8=50.27 m^2
3y=-6x+1 solve for y
Answer:
y= 2x +1/3

The local Farm Market sells peppers at five for $4.75.
How many peppers could you buy for $20?
Answer:
4
Step-by-step explanation:
Answer:
You can buy 4 peppers
Step-by-step explanation:
4.75$
4.75$
+ ___________
9.50$ (for 2 peppers. Now add another 4.75)
4.75$
+ ___________
14.25$ (for 3 peppers. Again, let's add another 4.75)
4.75$
+ ___________
19.00$ (for 4 peppers. Once a, let's add another 4.75)
4. 75$
+ ___________
23.75$
23.75$ is wayy over $20 . So your answer will be 4 peppers since 19.00 is smaller then $20

The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets
Complete Question
The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need
A) 9.50x + 6.50y ≥ 800
B) 9.50x + 6.50y < 800
C) 9.50x + 6.50y > 800
D) 9.50x + 6.50y ≤ 800
Answer:
A) 9.50x + 6.50y ≥ 800
Step-by-step explanation:
Let x be the number of adult tickets and y be the number of child tickets
We are told that the zoo wants to make at least $800, this means greater than or equal to $800
Therefore, inequality equation is given as:
$9.50 × x + $6.50 × y ≥ 800
= 9.50x + 6.50y ≥ 800
Therefore option A) 9.50x + 6.50y ≥ 800 is correct.
