midpoint (12, -9), endpoint (19, 0) the other endpoint is
Answer:
(5, -18)
Brainliest, please!
Step-by-step explanation:
(12, -9)(19, 0)
x distance: 7, y distance: 9
To get the other endpoint, we must apply the opposite.
x distance: -7, y distance: -9
(12, -9)
12 - 7 = 5, -9 - 9 = -18
(5, -18)
question 17 i need help answer is -16 but don’t know how
Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16

Mr Hamal had Rs 4,400.He purchased 6 kg of rice at Rs 75 per kg,2packets of oil at Rs 125 per packet and he gave Rs3,300 to his wife. he divided the remaining sum between his son and daughter equally , find the share of each them
Answer: Therefore, his son and daughter got Rs 200.
Step-by-step explanation:
6 kg of rice = 75*6 = Rs 450
2 packets of oil = RS 2*125 = RS 250
now total money he spent = Rs 450 + Rs 250 + Rs Rs 3,300
= Rs 700 + Rs 3,300
= Rs 4000
Money left = Rs 4,400-Rs 4000 = Rs 400
so
400/2 = Rs 200

Answer:
a = 3
Step-by-step explanation:
We can start by cross multiplying, which is a method to help solve proportions. We get:
5 * a = 3 * (a + 2)
Now, we can distribute the 3 and solve:
5a = 3a + 6
-3a -3a
2a = 6
/2 /2
a = 3
Answer:
[tex]a = 3[/tex]
Step-by-step explanation:
[tex] \frac{a}{a + 2} = \frac{3}{5} [/tex][tex]a \times 5=(a+2) \times 3[/tex]
[tex]5a=(a+2) \times 3[/tex]

The square root of 424 is between what two integers
Answer:
20 and 21
Step-by-step explanation:
424 = 400 + 20 + 4. √400 = 20, as √4 = 2
21² = (20 + 1)² = 400 + 40 + 1 = 441 > 424.

Complimentary angles have a sum of 90*. Thus when adding the two equations together, we must get 90*.
7x + 17 + 3x - 7 = 90 Combine like terms
10x + 10 = 90 Subtract 10 on both sides
10x = 80 Divide both sides by 10
x = 8
Answer:
x = 8
Step-by-step explanation
Complimentary angles have a sum of 90*. Thus when adding the two equations together, we must get 90*.
7x + 17 + 3x - 7 = 90 Combine like terms
10x + 10 = 90 Subtract 10 on both sides
10x = 80 Divide both sides by 10

María va de compras a una tienda departamental y adquiere los siguientes productos: 2 pantalones, 4 blusas, 3 pares de calcetas y 2 pares de tenis. El precio de los artículos por unidad es: pantalones $ 600.00, blusas: $350.00, calcetas: $120.00 y tenis: $ 950.00. Si María contaba con $5000.00, calcula cuánto dinero le sobró después de las compras realizadas.
Answer:
Pantalones = $600.00 × 2
$ 1,200.00
Blusas = $350.00 × 4
$ 1,400.00
Calcetas = $120.00 × 3
$ 360.00
Par de tenis = $950.00 × 2
$ 1,900.00
Total a pagar = $4,850.00
$5,000.00
- $4,860.00
Sobrante = $140.00

Can someone substitute this to find x and y
9514 1404 393
Answer:
-3 adult tickets were sold18 children's tickets were soldStep-by-step explanation:
Using the first equation to write an expression for y, we get ...
y = 15 -x
Substituting that into the second equation gives ...
30x +20(15 -x) = 270
10x +300 = 270 . . . . . . . . . simplify
10x = -30 . . . . . . . . . . . . . subtract 300
x = -3 . . . . . . . . . . . . . . divide by 10
y = 15 -(-3) = 18 . . . . find the corresponding value of y
The number of adult tickets sold is -3; the number of children's tickets sold is 18.
_____
Additional comment
If 15 tickets were sold for 270 the way your problem statement says, then the average ticket price is 270/15 = 18 per ticket. You show the ticket prices to be 20 for children and 30 for adults. That is, the average price is expected to be between 20 and 30. There is something wrong with this problem.

6=_-(-8) find the missing value
Answer:
-2
Step-by-step explanation:
when there are two negative signs directly next to each other, it becomes a positive. Set the equation. Let the unknown number be signified by the variable, x:
6 = x - (-8)
6 = x + 8
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 8 from both sides of the equation:
6 (-8) = x + 8 (-8)
6 - 8 = x
x = 6 - 8
x = -2
-2 is your missing value.

Hey there!
6 = ____ - (-8)
• We’re going to substitute the blank value as “x” because we don’t know the variable is just yet.. it is unknown
x - (-8) = 6
x + 8 = 6
SUBTRACT 8 to BOTH SIDES
x + 8 - 8 = 6 - 8
CANCEL out: 8 - 8 because that gives you 0
KEEP: 6 - 8 because that helps solve for the x-value
x = 6 - 8
6 - 8 = x
x = -2
Answer: -2
Good luck on your assignment and enjoy your day!

The expression (2x + a)(4x − 1) is equivalent to 8x2+ bx − 3. Find the value of b.
Answer:
b = 10
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms
(2x + a)(4x - 1) ← expand using FOIL
= 8x² + 4ax - 2x - a = 8x² + x(4a - 2) - a
Compare coefficients of like terms with
8x² + bx - 3
Then a = 3 ( constant term )
b = 4a - 2 ( coefficients of the x- term )
b = 4(3) - 2 = 12 - 2 = 10
Answer:
b = 10
Step-by-step explanation:
We can break those parenthesis like this
[tex](2x + a)(4x - 1) \\ = 2x(4x - 1) + a(4x - 1) \\ = 8{x}^{2} - 2x + 4ax - a[/tex]
And then combine the terms end with x we get
[tex]8 {x}^{2} - 2x + 4ax - a \\ = 8 {x}^{2} + 4ax - 2x - a \\ = 8 {x}^{2} + (4a - 2)x - a[/tex]
Now by comparing 2 expressions, we can see that a is 3, and b = 4a-2 = 12-2 = 10

Answer:
42 students
Step-by-step explanation:
If 4 students had to travel in cars, then 382 - 4 = 378 students traveled in the buses. Since there were 9 buses, 378 / 9 = 42. Therefore, there were 42 students in each bus.

Answer:
52 minutes
Step-by-step explanation:
Streaming Haunted Cave videos used the battery at the rate ...
(76% -16%)/(3·30 minutes) = 60%/(90 minutes) = (2/3)% per minute
Playing Top Pop used the battery at the rate ...
(63% -59%)/(24 minutes) = (4/24)% per minute = (1/6)% per minute
The remaining charge (in percent) after x minutes for Jorge's phone will be ...
J = 55 -2/3x
The remaining charge for Samantha's phone will be ...
S = 29 -1/6x
We can find the value of x that makes these equal:
J = S
55 -2/3x = 29 -1/6x
26 = 1/2x . . . . . . . . . . . . . . . add 2/3x -29 to both sides
52 = x . . . . . . . . . . . multiply by 2
It will be 52 minutes before the two phones have the same battery level.
