Can someone plz help me with this and explain how to do this math problem
Answer:
greater
Step-by-step explanation:
the reason is because if you allow x to have a value that is less than 3,
[tex] \sqrt{x - 3} [/tex]
will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction
[tex] \frac{3}{x + 2} [/tex]
if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

2.) LaSalle Peru Township High School is selling tickets to a football fundraiser dinner. On the first day of
ticket sales LP sold 4 adult tickets and 2 child tickets for a total of $52. LP took in $132 on the second day by
selling 12 adult tickets and 4 child tickets. What is the price each of one adult ticket and one child ticket?
Answer:
a = 7 and c = 12
Step-by-step explanation:
Set up 2 equations and use substitution:
4a + 2c = 52
12a + 4c = 132
In the first equation, c = 26 - 2a
We can plug that into the second equation to solve for a.
12a + 4(26 - 2a) = 132
a = 7
Plug a back in to either original equation to solve for c:
4(7) + 2c = 52
c = 12

3y - 2x = -7
5x + 3y = 28
Answer:
(5, 1 )
Step-by-step explanation:
Given the 2 equations
3y - 2x = - 7 → (1)
5x + 3y = 28 → (2)
Rearrange (1) expressing 3y in terms of x by adding 2x to both sides
3y = - 7 + 2x
Substitute 3y = - 7 + 2x into (2)
5x - 7 + 2x = 28
7x - 7 = 28 ( add 7 to both sides )
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5(5) + 3y = 28
25 + 3y = 28 ( subtract 25 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (5, 1 )
Answer:
-(3y-2x= -7)
3y+5x= 28
-3y+2x= 7
3y+5x= 28
7x=35
7x/7= 35/7
x=5
5(5)+3y= 28
25+3y=28
3y= 28-25
3y=3
3y/3=3/3
y= 1
3y-2x= -7
3(1) -2x= -7
3-2x= -7
-2x= -7-3
-2x= -10
-2x/-2=-10/-2
x= 5
chekin
5x+3y=28
5(5)+3(1)=28
25+3=28
28=28

A train leaves at 14.54 and arrives at its destination at 15.47. If the train travelled 66 km, what was it's average speed in km/h? Give your answer rounded to 1 dp. step by step explanation
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
- 14.54
= 14. 107 60 + 47
- 14. 54
53secs
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
Answer:
140°
Step-by-step explanation:
Three angle are labeled below the acre. The smallest angle is 3/8 as large as the 160 angle. Find the value of angle a
The value of the smallest angle is given as:
= 3/8 of the 160 angle
=3/8 × 160°
= 60°
The sum of the total angle = 360°
Hence:
360° = 60° + 160° + a
a = 360° - (60° + 160°)
a = 360° - 220°
a = 140°
Therefore, a = 140°
Solve by substitution.
y = 2.3 - 11
-2 + y = -4
Solution:
Answer:
Number 1: -8.7. Number 2: -2
Step-by-step explanation:
To find the first one, subtract 11 from 2.3.
2.3-11= -8.7 , so that's the answer for the first one.
To find the answer to the second one, just do -4+-2=-2, so that's the answer for the second one.

Considera a sequencia: 5,9,13,17,21...Indica a expressão geradora desta sequencia. 5n 4n+1 5n-1 3n+1
Responder:
Tn = 4n + 1
Explicación paso a paso:
Dada la secuencia aritmética
5,9,13,17,21 ...
Debemos encontrar el enésimo término de la secuencia
Tn = una + (n-1) d
a es el primer término = 5
n es el número de términos
d es la diferencia común
d = 9-5 = 13-9
d = 4
Sustituir en la ecuación
Tn = 5+ (n-1) (4)
Tn = 5 + 4n-4
Tn = 4n + 5-4
Tn = 4n + 1
Por tanto, el enésimo término de la secuencia se expresa como Tn = 4n + 1
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa .
-Abby walks at a speed of 8 feet per second.
-Melissa walks at a speed of 9 feet per second.
Abby had been walking for BLANK seconds when both students had walked exactly the same distance. (round to the nearest whole)
please help me
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed = [tex]\frac{distance}{time taken}[/tex]
For Abby,
8 = [tex]\frac{distance}{(x + 30)}[/tex]
distance = 8(x + 30) ................. 1
for Melissa,
9 = [tex]\frac{distance}{x}[/tex]
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The time taken is 270 seconds.
Given that,
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa . Abby walks at a speed of 8 feet per second. Melissa walks at a speed of 9 feet per second.Here we assume Melissa time be x and Abby time be x + 30Based on the above information, the calculation is as follows:
8(x + 30) = 9x
8x + 240 = 9x
x = 240
So Abby time should be
= 240 + 30
= 270

The points (0,3), (1,8), (2,17), and (3,30) are on the graph of a function. Which of the following equations represents that function?
a.2x^{2}-3x+3
b.2x^{2}+3x-3
c.2x^{2}-3x-3
d.2x^{2}+3x+3
Answer:
D. 2x^{2}+3x+3Step-by-step explanation:
Use the ordered pairs to determine the correct function
Point (0, 3)
x = 0 and y = 3- options A or D, the others result in y = -3Point (1, 8)
x = 1, y = 8 - option A.
2*1^2 - 3*1 + 3 = 2 - incorrectIt leaves us with option D
2*1^2 +3*1 + 3 = 8 - correctCheck other two pairs as well:
2*2^2 + 3*2 + 3 = 172*3^2 + 3*3 + 3 = 30This confirms option D is correct
1) Um barbante tem 10,85 metros de comprimento. Se você dividir em 5 pedaços de mesmo comprimento, quantos centímetros terá cada pedaço? * 1 ponto (a) 2,17 cm (b) 217 cm (c) 21,7 cm (d) 0,217 cm
Answer:
(b) 217 cm
Step-by-step explanation:
The computation of the number of centimeters will each have is shown below:
= Length of the string ÷ number of pieces
= 10.85 meters ÷ 5
= 2.17 meters
= 217 centimeters
hence, the correct option is b.
