what are the x and y intercepts of the function f(x)=3x+6
x-intercept = - 2 , y-intercept = 6
to find the intercepts, that is where the graph crosses the x and y axes
• let x = 0, in the equation for y-intercept
• let y = 0, in the equation for x-intercept
x = 0 : y = 0 + 6 = 6 ⇒ (0, 6 ) is the y-intercept
y = 0 : 3x + 6 = 0 ⇒ x = - 2 ⇒ (- 2, 0 ) is the x-intercept

Fuaad solved an absolute value inequality and expressed the solution as -12 < x > 7. What is another way to show Fuaad’s solution?
Solution: The another way to show the Fuaad's solution is [tex]x>7[/tex].
Explanation:
It is given that the solution of an inequality is [tex]-12<x>7[/tex].
It can be break in two parts [tex]-12<x[/tex] and [tex]x>7[/tex].
The inequality [tex]-12<x[/tex] means the values of x is greater than [tex]-12[/tex] and the inequality [tex]x>7[/tex] means the value of x is greater that than 7.
When we combine both results we get [tex]x>7[/tex] it means the value of x is greater than 7.
It can also represented by number line as shown in given figure.
The number line shows the values of x and red lines shows the solution of both inequalities [tex]-12<x[/tex] and [tex]x>7[/tex].
The common region shows the combination of both the possible inequalities, therefore the another way to show the Fuaad's solution is [tex]x>7[/tex].
Answer:
C (btw its x less than 7)
Step-by-step explanation:
Becuase the first option represents that the arrows go separate ways to infin.
the second option states that one variable is greater than of equal to and the other is only <
the third correctly shows and represents the inequality
the fourth one has the OR which means a number that is plugged in only needs to satisfy one of the inequalities which is not the point.
A man who is 6 feet tall casts a shadow that is 11 feet long. At the same time, a tree casts a shadow that is 33 feet long. What is the height of the tree?
Set up a proportion:
6 feet over 11 feet long equals x feet over 33 feet long
6/11 = x/33
198 = 11x
x = 18
The height of the tree is 18 feet tall
The height of the tree will be 18 feet.
What are ratio and proportion?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
A man who is 6 feet tall casts a shadow that is 11 feet long.
At the same time, a tree casts a shadow that is 33 feet long.
Then the height of the tree will be
Let x be the height of the tree.
Then we have
x / 6 = 33 / 11
x = 3 x 6
x = 18 feet

Evaluate the limit ....
It depends on how t is approaching 2.
In fact, if you consider the right limit, you have
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{|t-2|} [/tex]
But since t is greater than 2, t-2 is positive, and thus |t-2| = t-2.
So, the limit becomes
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{t-2} = \lim_{t \to 2^+} -1 = -1 [/tex]
On the other hand, if you consider the left limit, you have
[tex] \displaystyle \lim_{t \to 2^-} \dfrac{2-t}{|t-2|} [/tex]
But since t is less than 2, t-2 is negative, and thus |t-2| = -t+2.
So, the limit becomes
[tex] \displaystyle \lim_{t \to 2^+} \dfrac{2-t}{-t+2} = \lim_{t \to 2^+} 1 = 1 [/tex]
So, this limit does not exist, because the left and right limits exist but are not the same.

each block in Ton’s neighborhood is 2/3 mile long if he walk 4 1/2 blocks how far does he walk?
if each block is 2/3 miles long, and he walks 4 1/2 blocks, we can simply multiply to two. It looks like this:
(2/3)(4 1/2)
to multiply, make 4 1/2 into an improper fraction and multiply normally
(2/3)(9/4)
Ton walks 3 miles total.
Final answer:
Ton walks a total distance of 3 miles if each block is 2/3 mile long and he walks 4 1/2 blocks by multiplying the length of one block by the number of blocks walked.
Explanation:
The question asks about the total distance Ton walks if each block in his neighborhood is 2/3 mile long and he walks 4 1/2 blocks. To find the total distance, we can multiply the length of one block by the number of blocks walked:
Convert 4 1/2 blocks to an improper fraction: 4 1/2 = 9/2 blocks.
Multiply the length of one block by the number of blocks: (2/3 mile/block) × (9/2 blocks) = (2×9) / (3×2) = 18 / 6 = 3 miles.
Therefore, Ton walks a total distance of 3 miles.

Find a polynomial function of degree 3 such that f (2) = 24 and x– 1, x and x+ 2
are factors of the polynomial.
f(x) = 3x³ + 3x² - 6x
given the factors of the polynomial , then
f(x) =ax(x - 1)(x + 2) ( a is a multiplier )
to find a use f(2) = 24
f(2) = 2a(1)(4) = 24 ⇒8a = 24 ⇒ a = 3, thus
f(x) = 3x(x² + x - 2) = 3x³ + 3x² - 6x
The polynomial function is [tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].
Given that,
f(2) = 24.And, x– 1, x and x+ 2 represents the factors of the polynomial.Now based on the above information, the calculation is as follows:
f(x) =ax(x - 1)(x + 2)
Here a is a multiplier.
Now
f(2) = 24
f(2) = 2a(1)(4) = 24
8a = 24
a = 3
It can be write as
[tex]f(x) = 3x(x^2 + x - 2)[/tex]
[tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].
Therefore we can conclude that the polynomial function is [tex]f(x) = 3x^3 + 3x^2 - 6x[/tex].

I need help with a question before my test: how do I tell if a graph has rotational Symmetry if it is not an odd function and do all odd functions have point symmetry??
Answer:
If you know that the function is not odd, you know that the graph does not have rotational symmetry
Step-by-step explanation:
There is a theorem that says: "A function is odd if, and only if, its graph is symmetric with respect to the origin, or it has rotational symmetry in 180 ° with respect to the origin"
This statement is equivalent to:
If a function is odd, its graph has rotational symmetry with respect to the origin
If a graph has rotational symmetry with respect to the origin then the function is odd.
Therefore, it is impossible for the graph to have rotational symmetry with respect to the origin and the function is not odd.
Then, if you know that the function is not odd, you know that the graph does not have rotational symmetry
Which of the graphs below represents the equation 8x-y=4
Graph Z
Slope: 8
Y-Intercept: -4
Answer:
Graph X
Step-by-step explanation:
[tex]8x-y=-4[/tex]
To graph the equation we write it in the form of y=mx+b
Subtract 8x from both sides
[tex]-y=-8x-4[/tex]
Divide both sides by -1
[tex]y=8x+4[/tex]
In y=mx+b, m is the slope and b is the y intercept

A stadium has 50 comma 00050,000 seats. Seats sell for $3030 in Section A, $2424 in Section B, and $1818 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1 comma 288 comma 8001,288,800 from each sold-out event. How many seats does each section hold?
A= B+C
As given, A+B+C = 50000 seats
A+(B+C) = 50000
2A = 50000
A= 25000 seats
Now section A sells seats at $30 each
So, [tex]25000\times30=750000[/tex]
Now, B+C = 25000
B = 25000-C
B sells at $24 and C sells at $18
So, 24B+18C = 538800
Now as section A incurs an amount of $750000 from booking, so B and C will incur 1288800-750000 = 538800 where $1288800 is the total booking amount.
24B+18C = 538800
[tex]24(25000-C)+18C=538800[/tex]
[tex]600000-24C+18C=538800[/tex]
6C = 61200
C = 10200
Now, B = 25000-C
B = 25000 - 10200 = 14800
Hence, section A has 25000 seats
Section B has 14800 seats
Section C has 10200 seats
