Given:
The inequality is:
[tex]y>2x-3[/tex]
The point is (3,3).
To find:
Whether the coordinate pair (3, 3) is a solution to the given inequality or not.
Solution:
We have,
[tex]y>2x-3[/tex]
Check the inequality for the point (3,3). Substituting [tex]x=3,y=3[/tex], we get
[tex]3>2(3)-3[/tex]
[tex]3>6-3[/tex]
[tex]3>3[/tex]
This is a false statement because 3 is not greater than itself.
Since (3,3) does not satisfy the given inequality, therefore (3,3) is not a solution to the given inequality.
Now we can check the solution graphically. From the graph it is clear that the point (3,3) lies on the boundary line.
The boundary line is a dotted line, it means the point on the boundary line are not included in the solution set.
Therefore, (3,3) is not a solution to the given inequality.

what is the a, b, and c of the following quadratic y = - 4x ^ 2 + 5x - 3
Answer:
A = -4
B = 5
C = -3
Step-by-step explanation:
Standard form of a quadratic equation is y = Ax² + Bx + C
In the quadratic y = -4x² + 5x - 3, we can use this standard form to find A, B, and C.
Since -4 is the coefficient to x², A is -4.
Since 5 is the coefficient to x, B is 5.
Lastly, since -3 is the last term, C is -3.
So, the answer is:
A = -4
B = 5
C = -3

find the missing number so that the equation has no solutions
__x+6 = 2(-3x + 1) + x - 16
Answer:
-5
Step-by-step explanation:
-5x+6 = 2(-3x + 1) + x - 16
-5x+6 = -6x + 2 + x - 16
-5x+6 = -5x -14
+6≠-14⇒x∈Ф

SED
Answer:
C.
Step-by-step explanation:
Reorder the data set, from least to greatest.
3, 5, 7, 8, 9, 9, 10, 11, 12
Mean: 8.2 -> you get this by adding up all the numbers in the data set by how many numbers in the data set. For example, 3+5+7+8+9+9+10+11+12= 74 divide by 9 (the numbers in the data set) = 8.2 (repeated infinitely).
Median: 9 -> you get this by finding the number in the middle of the data set, which is why you have to reorder the data set for the beginning to make this easier.
Mean (with 45): 11.9 -> 119 when you add up all the numbers, then divide by 10 because that's have many numbers in the new data set.
Median (with 45): 9 -> When there are two numbers in the middle of the data set, add them up and divide by two. For example, 9+9=18/2= 9

Show that f(x) = x^2 and g(x) = 1000x^2 grow at the same rate.
Answer:
You do not use the first derivative to find the rate you need to take the limit ratio as x approaches positive infinity. We use positive and not negative infinity because our function is increasing and not decreasing. The ratio ends up being 1/1000 meaning that this a finite non zero number. Which proves that they grow at the same rate

Answer: I think it is going to be 42.5
Step-by-step explanation: I think that because is you divide the 29 by 7.5 you get 3.86. Multiply the 11 by 3.86 and you get 42.46. If you round to the nearest tenth that would be 42.5

The are of a rectangular trampoline is 112ft. The length of the trampoline is 6ft greater than the width of the trampoline. This situation can be represented by the equation x^2+6x-112=0 what is the width of the trampoline in feet
Answer:
8cm
Step-by-step explanation:
let x = width
x^2+6x-112=0
we would solve this using the factorization method
the factors of -112x^2 that would add up to 6x are 14x 8x
x^2 - 8x + 14x - 112 = 0
factorise
x(x - 8) + 14(x - 8) = 0
x+ 14 = 0
x - 8 = 0
x = 8
the width is 8cm
x = -14
Find the area of the following figure.
252 [tex]cm^{2}[/tex]
400 [tex]cm^{2}[/tex]
312 [tex]cm^{2}[/tex]
300 [tex]cm^{2}[/tex]
Answer:
312 cm²
Step-by-step explanation:
The figure is composed of a rectangle and 2 congruent triangles
area of rectangle = 16 × 12 = 192 cm²
area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × 12 × 10 = 12 × 10 = 120 cm²
Area of figure = 192 + 120 = 312 cm²

14. Find mMK please :)
Answer:
Step-by-step explanation:
11) strategy: since they tell us. indirectly, that the length of JK is the same as LM then we can set those two equal, solve for X and then.. when we have X we can figure out the lenght of JK and LM and then just divide that by 2 go get PK ( :0 Player Killer ??? no , not that PK)
solve JK and LM
3x + 23 =9x-19
42 = 6x
7 = x
now that we know x = 7 plug it into either equation to come up with the length of JK or LM . I'll pick JK just b/c it was 1st
3(7) + 23 = JK
21+23 = JK
44 = JK
now take half of 1/2*JK= 22 that is PK ( are you sure that 's not player killer?)
PK = 22
12) strategy: set the two arcs BG and GC equal and solve for X, then plug x into either equation and the multiply the answer by 2 to find arc AB
9x-20 = 5x + 28
4x = 48
X = 12
9(12) -20 = BG
88 = BG
2*88 + AB
176 = AB
13) done
14) strategy: find the angle at L, and that will also be the arc of MK
copy and past the below helpful trig functions into your computer
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
copy and past the above :
use which ever trig function you want , we have all the sides of the triangle, I'll use CAH
Cos(Ф) = 9/15
Ф = arcCos(9/15)
Ф = 53.13010°
arc MK = 53.13010°
15) strategy: arc JK is just 2 times MK
2*MK = 106.26020°
arc MK = 106.26020°
16) find arc JPK strategy: JPK is just the remaining part of a full circle of 360 - MK = 253.7397°
arc JPK = 253.7397°
Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.
Answer:
[tex]n = 5[/tex]
Step-by-step explanation:
Given
[tex]2(n+1)! + 6n! = 3(n+1)![/tex]
Required
Find n
Simplify (n + 1)!
[tex]2(n+1)*n! + 6n! = 3(n+1)*n![/tex]
Factorize
[tex]n![2(n+1) + 6] = 3(n+1)*n![/tex]
Divide both sides by n!
[tex]2(n+1) + 6 = 3(n+1)[/tex]
Open brackets
[tex]2n + 2 + 6 = 3n + 3[/tex]
[tex]2n + 8 = 3n + 3[/tex]
Collect like terms
[tex]2n - 3n = 3 -8[/tex]
[tex]-n =-5[/tex]
Multiply both sides by -1
[tex]n = 5[/tex]
