Answer:
y = -3x + 8
Step-by-step explanation:
(1, 5) ; (-2, 14)
[tex]Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{14-5}{-2-1}\\\\=\frac{9}{-3}\\\\=-3[/tex]
m = -3 ; (1 , 5)
Equation: [tex]y-y_{1}=m(x-x_{1})[/tex]
y - 5 = (-3)(x - 1)
y - 5 = -3x + 3
y = -3x + 3 + 5
y = -3x + 8
Before using the Gizmo, consider an arithmetic sequence with a first term (a1) of 4 and a common difference (d) of 3.
Challenge: What are the first five terms of the sequence (from lowest to highest)?
Answer:
4, 7, 10, 13 and 16Step-by-step explanation:
The nth term of an arithmetic sequence is expressed as [tex]Tn = a+(n-1)d[/tex].
a is the first term of the sequence
d is the common difference
n is the number of terms
Given the first term a = 4 and common difference d = 3, we can calculate the first five terms of the sequence using the formula.
If n = 2
[tex]T_2 = 4+(2-1)*3\\T_2 = 4+(1)*3\\T_2 = 4+3\\T_2 = 7\\\\when \ n = 3;\\T_3 = 4+(3-1)*3\\T_3 = 4+(2)*3\\T_3 = 4+6\\T_3 = 10\\\\when\ n = 4\\T_4 = 4+(4-1)*3\\T_4 = 4+(3)*3\\T_4 = 4+9\\T_4 = 13\\\\when\ n = 5\\T_5 = 4+(5-1)*3\\T_5 = 4+(4)*3\\T_5 = 4+12\\T_5 = 16\\[/tex]
The first five terms of the sequence from lowest to highest are 4, 7, 10, 13 and 16

What are the x-intercepts of the graph of the function f(x) = x2 + 4x – 12? (–6, 0), (2,0) (–2, –16), (0, –12) (–6, 0), (–2, –16), (2, 0) (0, –12), (–6, 0), (2, 0)
Answer:
(-6, 0) and (2, 0)
Step-by-step explanation:
To find the x-intercepts, we can factor the expression:
f(x) = x² + 4x - 12
2 factors of -12 that add up to 4 are 6 and -2
(x + 6)(x - 2)
Set each factor equal to 0 and solve for x:
x + 6 = 0
x = -6
x - 2 = 0
x = 2
So, the x intercepts are (-6, 0) and (2, 0)
Answer:
It's the first option, (-6, 0) (2, 0)

After solving for both variables, you find that each bus can hold 59 students and each van can hold 18 students.
Step-by-step explanation:
You can find the amount of students each vehicle can carry by representing the two scenarios in equations.
You are trying to find how many students will fit in each bus or van, so the two variables used will be "b" to represent how many students can fit in a bus and "v" to represent how many students can fit in a van.
High school A used 1 van and 6 buses, so there will be 1"v" and 6"b" for 372 students.
High school B used 4 vans and 12 buses, so there will be 4"v" and 12"b" for 780 students.
Now, represent these in equations:
[tex]v+6b = 372\\4v + 12b = 780[/tex]
We can use substitution to solve this system:
[tex]v + 6b = 372[/tex] can be rewritten as [tex]v = 372 - 6b[/tex] after subtracting 6b from both sides. You can then substitute this new value of "v" into the other equation to solve for "b":
[tex]4(372-6b) + 12b = 780\\1488 - 24b + 12b = 780\\1488 - 12b = 780\\-12b = -708\\b = 59[/tex]
After solving for b, you can then substitute the new value of b into the other equation to find the value of v:
[tex]v + 6(59) = 372\\v + 354 = 372\\v = 18[/tex]
After solving for both variables, you find that each bus can hold 59 students and each van can hold 18 students.
Answer:
Van: 18, Bus: 59
Step-by-step explanation:
b - number of students that bus can carry
v - number of students that van can carry
6•b + 1•v = 372 - students from A
6b + v = 372 ⇒ v = 372 - 6b
12•b + 4•v = 780 - students from B
12b + 4(372 - 6b) = 780
12b + 1488 - 24b = 780
- 12x = - 708
b = 59
v = 372 - 6•59 = 372 - 354 = 18

hope this helps...
Good luck on your assignment...
Answer:
t= 0.2x (2/y + 3/z)
Step-by-step explanation:
Distance:
40% of the race= 0.4x
60% of the race= 0.6x
Speed:
y m/s at first part and z m/s at second part
Time:
time= distance/speed, it also consists on 2 parts due to different speed
t= 0.4x/y + 0.6x/z
or
t= 0.2x (2/y + 3/z) seconds is the answer

2. The dimensions of the original rectangle = L by W
The dimensions of the lager rectangle = 1.5·L by 2·W
1.5·L × 2·W = 30
Given that L > W
∴ L×W = 30/(1.5 × 2) = 30/3 = 10

Jim rented a truck for one day. There was a base fee of $17.99, and there was an additional charge of 76 cents for each mile driven. Jim had to pay $236.11 when he returned the truck. For how many miles did he drive the truck?
Answer:
287 miles
Step-by-step explanation:
The base fee was $17.99 and an additional 76 cents ($0.76) for every mile.
We can represent the amount he will pay for rent with the equation below:
C = 17.99 + 0.76m
where m = number of miles driven
Jim paid $236.11, therefore:
236.11 = 17.99 + 0.76m
0.76m = 236.11 - 17.99
0.76m =218.12
m = 218.12 / 0.76 = 287 miles
Jim drove 287 miles.

Bella is buying balloons for a back to school celebration. She sees there are 4
packages of 15 balloons for $18 and 5 packages of 10 balloons for $16. Which is
a better deal? How do you know? Are you comfortable with Bella's buying
habits? Why or why not? help plsss
Answer:
The first unit price ($0.30/balloon) beats the second ($0.32/balloon).
Step-by-step explanation:
4 packages of 15 balloons for $18 works out to 1 package of 15 balloons for $18/4, or $4.50. That'd be
$4.50
---------------- = $0.30/balloon.
15 balloons
Next: 5 packages of 10 for $16 works out to 1 package of 10 for $16/5, or
1 package of 10 for $3.20. That'd be
$3.20
----------------- = $0.32/balloon
10 balloons
The first unit price ($0.30/balloon) beats the second ($0.32/balloon).
If Bella understands the math involved in finding unit costs and actually does the work prior to buying anything, then I'm comfortable with her buying habits.
Both deals are almost same.
We have a girl Bella who is buying balloons for a back to school celebration. She sees there are 4 packages of 15 balloons for $18 and 5 packages of 10 balloons for $16.
We want to know which is a better deal with appropriate reason. We have to morally investigate on the basis of our thinking whether or not Bella's buying habits are good or not.
If 'n' balloons cost $ x, then the cost of 1 balloon will be?The cost of 1 balloon will be = [tex]\frac{x}{n}[/tex] (in dollars)
Now, according to question -
Case 1 :
The total number of balloons are 15 x 4 = 60 balloons.
The cost of these 60 balloons is $ 18.
Cost of 1 balloon = [tex]\frac{18}{60}[/tex] = $ 0.3
Case 2 :
The total number of balloons are 10 x 5 = 50 balloons.
The cost of these 60 balloons is $ 16.
Cost of 1 balloon = [tex]\frac{16}{50}[/tex] = $ 0.32
It can be concluded that the both deals are almost same and i think that it is okay to spend a bit amount of money for a back to school party.

Para calcular de cuántas maneras se puede seleccionar x elementos de un grupo de n elementos podemos usar la siguiente fórmula:
[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]
Si vas a elegir 3 personas de entre 6 matrimonios y dos miembros de la misma pareja no pueden ser elegidos, entonces podemos decir que se está eligiendo 3 matrimonios y en cada matrimonio se está eligiendo un representante.

5. In an A.P, the sum of three consecutive terms is 24. When 1 is subtracted to the first term, 2 to the
second, then the terms form a G.P. Find the terms of the A.P.
Answer:
Step-by-step explanation:
Let the three numbers be a-d, a, a+d being a series in AP.
The sum of the three numbers is 24 = a-d+ a+ a+d = 3a
Thus a = 8.
Now a-d-1, a-2, a+d form a GP. It means, the common ratios should be equal or the middle term should be the Geometric Mean of the first and third terms, or
(a-d-1)(a+d) = (a-2)^2 or
(8-d-1)(8+d) = (8-2)^2, or
(7-d)(8+d) = 36, or
56 -8d +7d -d^2 = 36, or
56 -8d +7d -d^2 - 36 = 0, or
d^2 +d -20 = 0
(d+5)(d-4) = 0
Thus d = -5 or 4
So the AP is 13,8,3 or 4,8,12
Check: 13,8,3 in AP becomes (13–1), (8–2), 3 = 12, 6, 3 which is a GP with r = (1/2)
4,8,12 in AP becomes (4–1), (8–2), 12 = 3, 6, 12 which is a GP with r =2
