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

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]

[tex]5a=3a+6[/tex]

[tex]5a−3a=6[/tex]

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.

Answer: -15,-12,10,12,26

Step-by-step explanation:

The expression (2x + a)(4x − 1) is equivalent to 8x2+ bx − 3. Find the value of b.

Answers

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

on monday 382 students went on a trip to the zoo. all 9 buses were filled and 4 students had to travel in cars. how many students were in each bus?

Answers

382 - 4 = 378
378/9 = 42
so there are 42 students on each bus

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.

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

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

6=_-(-8) find the missing value

Answers

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

Answer:

-3 adult tickets were sold18 children's tickets were sold

Step-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.
