Answer:
Yes
Step-by-step explanation:
To determine whether a relation is a function or not, we can do a vertical line test. First, get something like a ruler, put it vertical, then scan it on the relation. If the ruler hits one point of the line, then it is a function. If the ruler hits two points at once, then it is not a function. This passes the vertical line test, because when the ruler hits the relation it only hits one point at a time, making it a function. I hope this helps, I hope it's not wrong but I don't think it is.

2(2z– 3) = 18
Please help I will mark brainliest answer please help
Answer:
z=6
Step-by-step explanation:
2(2z−3)=18
Divide each term by 2 and simplify.
2z−3=9
Move all terms not containing z to the right side of the equation.
2z=12
Divide each term by 2 and simplify.
z=6
Hope this helps! :) Plz mark as brainliest!
Answer:
z =6
Step-by-step explanation:
so we simplify from both side.
2( 2z - 3) = 18
*2 *2
4z - 6 = 18
+ 6 +6
4z = 24
then we divide both sides from 4
4z / 4 = 24/ 4
z = 6

Answer:
- 12x + 24
Step-by-step explanation:
Since the perimeter is 2(length) + 2(width) your equation would start out as:
2[-2(3x-1)] + 2(10x)
2[-2(3x-1)] + 20 = 2(-6x + 2) + 20
2(-6x + 2) + 20 = - 12x + 24

En un cuartel, los 2/3 de las personas que hay son soldados y el resto son oficiales, suboficiales y jefes. El número de jefes es 1/12 del resto y el número de oficiales es cuatro veces mayor que el número de jefes. Halla el número de oficiales, suboficiales y jefes, sabiendo que hay 600 soldados. *
Answer:
25 jefes
100 oficiales
175 suboficiales
Step-by-step explanation:
Se nos dice que hay 600 soldados que está representado por una fracción de 600
Podemos obtener el número total de personas en el cuartel.
Representemos el número total de personas en el cuartel como: B
2/3 × B = 600
2B / 3 = 600
Cruz multiplicar
2B = 600 × 3
B = 1800/2
B = 900
Por lo tanto, el número total de personas en el Cuartel es de 900 personas.
De la pregunta se nos dice que:
el resto son oficiales, suboficiales y jefes.
Calcule el número total de personas en el cuartel con 1
El resto se representa como:
1 - 2/3 = 1/3
El número de jefes es 1/12 del resto
Por lo tanto,
= 1/12 de 1/3
= 1/12 × 1/3
= 1/36
El número total de personas = 900
Por tanto, el número de jefes = 1/36 × 900
= 25 jefes
Tenemos 25 jefes
El número de oficiales es cuatro veces mayor que el número de jefes.
= Número de oficiales = 4 (1/36)
= 4/36
= 1/9
El número total de personas = 900
Por lo tanto, el número de oficiales = 1/9 × 900
= 100 oficiales
Tenemos 100 oficiales
El número de suboficiales se calcula como:
900 - (600 + 25 + 100)
= 900 - 725
= 175
The teacher is handing out note cards to her students. She gave 2 note cards to the first student, 6 note cards to the second student, 18 note cards to the third student, and 54 note cards to the fourth student. If this pattern continues, how many note cards will the teacher give to the fifth student?
Answer:
162 because if you multiply all of them by 4 you get the answer
The teacher will give 162 note cards to the fifth student.
Students = 1 2 3 4 5
Number of handing = 2 6 18 54 ?
out note cards
It is pattern of series, its ratio with preceding values remains equal.
Here,
First term(a) = 2
common ratio(r) = 3
Nth term = ar^(n-1)
5th term = 2 x 3^(5-1)
= 2 x 3^4
= 162

NEED HELP FAST PLEASEEE!!!! When Talia performs in a cheerleading competition she makes 2 mistakes
in every 3 minutes of performance. If she performs for a total of 18
minutes in the competition tonight, how many mistakes will she
make?
A. 12
B. 15
C. 16
D. 27
E. 30
Answer:
(A) 12
Step-by-step explanation:
This is actually very simple!
If Talia makes 2 mistakes every 3 minutes then the ratio is 2:3
Going along with that if you know how ratios work then that should be easy. But this is also the long way. You dont really need to know ratios you just need to know the steps but knowing ratios would be helpful.
You first divide
18 / 3 = 6
Then multiply
6 x 2 = 12
That's it!

Martina purchased a prepaid phone card for $15 . Long distance calls cost 8 cents a minute using this card. Martina used her card only once to make a long distance call. If the remaining credit on her card is $11.48 , how many minutes did her call last?
Answer:
44 minutes
Step-by-step explanation:
With regards to the above information, we can calculate the minutes in which Martina's call lasted as shown below;
We can make y represent the minutes
15 - 8y/100 = 11.48
15 - 0.08y = 11.48
15 - 11.48 = 0.08y
0.08y = 3.52
y = 3.52/0.08
y = 44
It therefore means that Martina's call lasted for 44 minutes.

Alden measured the water level in his pool each day. Ever day, the water level went down 1 1/2 inches he measured the pool for 5 straight days. Which value in this situation could be represented by a negative number?
Answer:
Decrease or decline in water level per day
Step-by-step explanation:
Given the question above ;
The situation which could be repress Ted by a negative number is the decrease in the water level of the pool being measured :
It could be expressed as - 1 1/2 inches per day
Fall, decrease, loss or reductions are usually modeled in mathematics using the negative sign as it portrays a negative adjustment or reduction in the original amount of a commodity, item or phenomenon.
Furthermore, total decline after 5 days will be ;
-1 1/2 * 5 = (-3/2 * 5) = - 15/2 = - 7.5 inches

Find the sum of the interior angle measures of a convex 20-gon (a twenty-sided polygon).
Answer:
3,240°
Step-by-step explanation:
Sum of interior angles of n-sided polygon is given as (n - 2)180. Where n = number of sides of the polygon.
Sum of angles of a convex 20-gon = (20 - 2)180
= (18)180 = 3,240°
Sum of interior angles of a convex 20-gon = 3,240°
Answer:
3,240
Step-by-step explanation:
(n-2)180 n is the number of sides
Substitute 20 for n, then simplify
(20 - 2)180 = (18)180 = 3,240

21) 64=8(r+2)
Step 1: Simplify both sides of the equation.
64=8(r+2)
64=(8)(r)+(8)(2)(Distribute)
64=8r+16
Step 2: Flip the equation.
8r+16=64
Step 3: Subtract 16 from both sides.
8r+16−16=64−16
8r=48
Step 4: Divide both sides by 8.
8r
8
=
48
8
r=6
29) Step 1: Simplify both sides of the equation.
−4(r+6)=−63
(−4)(r)+(−4)(6)=−63(Distribute)
−4r+−24=−63
−4r−24=−63
Step 2: Add 24 to both sides.
−4r−24+24=−63+24
−4r=−39
Step 3: Divide both sides by -4.
and you get r= 39\4
hope that helps
Answer: r = 6
Step-by-step explanation:
64= 8(r+2)
64/8 = 8(r+2) / 8 divide both sides by 8
8 = r + 2 The eights cancel out
- r = 2 + 8 Move the variable to the left and change its sign
- r = - 6 to get id of the negative -r make the 6 a positive
r=6
-4(r + 6) = -63
- 4r - 24 = -63 Distribute 4 through ( ) -4 x4 -4 x6
-4r =63 + 24 Move -24 to the right (making it a positive )
-4r = 39
-4r / -4 = 39 /4 divide both sides by -4
r= 39/4
