Please help me ASAP!!!

Answer:

The solution set is (5,6).

Step-by-step explanation:

Given equations are:

-6x + 6y= 6         Eqn 1

-6x + 3y=-12      Eqn 2

Subtracting Eqn 2 from Eqn 1

(-6x+6y)-(-6x+3y)= 6-(-12)

-6x+6y+6x-3y=6+12

3y = 18

Dividing both sides by 3

[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]

Putting y=6 in Eqn 1

-6x+6(6)=6

-6x+36=6

-6x=6-36

-6x=-30

[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]

Hence,

The solution set is (5,6).

Hopefully this helps with understanding.

Answer:

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Step-by-step explanation:

You need to complete the square before you can take the square root of both sides.

[tex] x^2 + 7x + 10 = 0 [/tex]

Subtract 10 from both sides.

[tex] x^2 + 7x = -10 [/tex]

To complete the square, you need to add the square of half of the x-term coefficient to both sides.

The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.

[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]

[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]

Now we use the square root property, if

[tex] x^2 = k [/tex], then

[tex] x = \pm \sqrt{k} [/tex]

[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]

[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]

[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex]   or   [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]

[tex] x = -\dfrac{4}{2} [/tex]   or   [tex] x = -\dfrac{10}{2} [/tex]

[tex] x = -2 [/tex]   or   [tex] x = -5 [/tex]

Answer:

The time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Step-by-step explanation:

Given

To determine

Time period t = ?

Using the formula

I = Prt

t = I / Pr

substitute I = $60, P = $750 and r = 0.04 in the equation

t = 60 / ( 750 × 0.04 )

t = 2  years

Therefore, the time required to  accumulate simple interest of $ 60.00

from a principal of $ 750.00  at an interest rate of 4% per year  is 2 years.

Answer: $66.7

Step-by-step explanation:

$58 spent on dinner

Gives 15% of the bill as tip

15% of 58 = 8.7

$58 + $8.7 = $66.7

Answer:

- 1.15585%

Step-by-step explanation:

Given that:

Sum of stock at beginning = $10,335.24

Sum of stock at the end of the day = $10,215.78

Rate of change of the Down Jones on that day :

The change in price on the day:

Ending - Beginning

10,215.78 - 10,335.24 = −119.46

The rate if change is thus ;

(Change in price / beginning stock price) * 100%

(-119.46 / 10,335.24) * 100%

-0.0115585 * 100%

- 1.15585%

Answer: -1.2%

Step-by-step explanation:

Absolute value function:

Swim 3 feet under water => |-3|

Stand 20 feet above => |20|

Using the absolute value function,

we have |-3| = 3 and |20| = 20.

Since 3 is less than 20, |-3| < |20|. (C)

Answer: 77

Step-by-step explanation:

Answer:well for the first one I am not sure but I think that since four is over the x there should be 4/x + 3 so tragically I don’t know the answer but I think it should be 12 the x should be 12 because 4x3=12 so yea 12

Step-by-step explanation:and for the other one I don’t know but ima try it should be two because 2x2=4 and so y=1-2x2-4 that’s what I think sorry. I got it wrong and do good on your test for me please

Answer:

72 cm

Step-by-step explanation:

Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.

Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.

Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.

Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.

Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.

So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm

Complete question :

At 10:00 am, Han and Tyler both started running toward each other from opposite ends of a 10 mile path along a river. Han runs at a pace of 12 minutes per mile Tyler runs at a pace of 15 minutes per mile how far does Han run after a half hour

Answer:

2.5 miles

Step-by-step explanation:

Given :

Distance between Horn and Tyler = 10 miles

Horn's pace = 12 minutes per mile

Tyler's pace = 15 minutes per mile

Horn's distance after half an hour :

Time = Half an hour = 30 minutes

Horn's speed = distance / time

Horn's speed = 1 mile / 12 minutes = 0.83333 miles per minute

Hence, Horn's distance after half an hour :

Distance = speed * time

Distance = 0.83333 miles per minute * 30 minutes

Distance = 2.5 miles

Answer:

54 teachers

Step-by-step explanation:

Step one:

given data

The ratio of teachers to students on a field trip to New York City is 2 to 9.

That is the ratio is 2:9

We are told that there are 243 students

Required

We want to find the number of teachers

Step two:

Applying the part to part method we have

let the number of teachers be x

2/9= x/243

cross multiply we have

9x= 243*2

9x= 486

divide both sides by 9

x= 54

Hence there are 54 teachers
