**Answer:**

**Step-by-step explanation:**

Find the centre first by reoriganisation it into the form (x - cx)^2 + (y -cy)^2 = r^2

x^2 + y^2 + 6x -6y +5 = 0

(x + 3)^2 - 9 + (y - 3)^2 - 9 + 5 = 0

(x + 3)^2 + (y - 3)^2 = 13

The radius does not matter the centre is ( -3, +3)

The diameter must pass through the center so substituting into the equation for the line

2x-y+a = 0

-6 -3 + a = 0 so a = 9

The **value **of '**a**' is **0 **and this can be determined by using the** standard form **of the **equation **of a **circle**.

Given :

Equation of a Circle -- [tex]x^2-2x+y^2-4y-4=0[/tex]

Equation of a Line -- 2x - y + a = 0

The following steps can be used in order to determine the value of 'a':

Step 1 - First make the **equation **of a **circle **in **standard form**.

[tex]x^2-2x+y^2-4y-4=0[/tex]

[tex](x-1)^2-1+(y-2)^2-4-4=0[/tex]

[tex](x-1)^2+(y-2)^2 = 3^2[/tex]

Step 2 - From the above step, it can be **concluded **that the **center **of the **circle **is (**1,2**).

Step 3 - If (**1,2**) is the **center **of the **circle **then it also satisfies the **equation **of **diameter **(**2x - y + a = 0**).

2x - y + a = 0

2(1) - 2 + a = 0

**a = 0**

What is the ratio of 1/2 to 6?

(A) 12

(B) 3

(C)1/3

(D)1/6

(E) 1/12

**Answer:**

e, 1/12

**Step-by-step explanation:**

**1) turn the first fraction into a whole number, the closest whole number being 1.**

**what did you multiply 1/2 by to get 1? the answer would be 2. **

**whatever you do to oneside, do to the other. when you multiply 6 by 2, you get twelve. **

**therefore, the answer is 1/12**

A riverboat travels 54 km downstream in 2 hours. It travels 57 km upstream in 3 hours. Find the speed of the boat and the speed of the stream

Here we must write and solve a** system of equations **to find the **speed **of the boat and the **speed **of the stream. We will find that the boat's **speed **is **23km/h **and the river's **speed **is **4km/h.**

First, remember the relation:

Distance = Speed*Time.

Now let's define the **variables **we will be using:

When the boat travels downstream, the total **speed **of the boat is the **speed **of the boat plus the **speed **of the river, and we know that in that case it travels 54km in 2 hours, then:

54km = (B + R)*2h

When the boat travels upstream, we must subtract the **speed **of the river. In that case, we know that the boat travels 57km in 3 hours, then we have:

57km = (B - R)*3h

Then our **system of equations** is:

54km = (B + R)*2h

57km = (B - R)*3h

To solve this, first, we need to isolate one of the **variables **in one of the **equations**, let's isolate B in the second one:

57km = (B - R)*3h

57km/3h + R = B

19 km/h + R = B

Now we can replace that in the other **equation**:

54km = (B + R)*2h

54km/2h = B + R

27 km/h = B + R = (19 km/h + R) + R

Now we can solve this for R:

27 km/h = 19km/h + 2*R

27 km/h - 19km/h = 2*R

8 km/h = 2*R

(8km/h)/2 = 4km/h = R

Now that we know the value of R, we can use:

B = 19 km/h + R = 19 km/h + 4km/h = **23 km/h**

So the boat's **speed **is **23km/h** and the river's **speed **is **4km/h.**

(b) A sum of money was to be shared among three friends Keisha, Tracey, and Kerry-Ann, in the

ratio 7:9:11 respectively. If Kerry-Ann received $3,300.00, find the sum of money that was

between the three friends.

The **sum** of money that was **shared** between the** three friends** is **$8100**

The **ratio** at which the **money** was** shared** = 7 : 9 : 11

Total ratio = 7 + 9 + 11

**Total ratio** = 27

**Amount** received by **Kerry-Ann** = $3300

Let the **total amount** shared by the three friends be T

**Amount received** by **Kerry-Ann** = (11/27) x T

3300 = 11T / 27

11T = 27(3300)

11T = 89100

how many seconds are there in 3 minute By the process

**Answer:**

**Step-by-step explanation:**

You can easily convert 3 minutes into seconds using each unit definition:

Minutes

minute = 60 s = 60 s

Seconds

1 s

= 1 sec / 60 = 0.01667 min

With this information, you can calculate the quantity of seconds 3 minutes is equal to.

In 3 min there are 180 s.

Which is the same to say that 3 minutes is 180 seconds.

How do I divide using "partial remainders"?

**Step-by-step explanation:**

When the modulus is ∞, the result is equal to the value in ST(0). Otherwise, C2 is set, and the result in ST(0) is called the partial remainder. The exponent of the partial remainder will be less than the exponent of the original dividend by at least 32. Using partial remainders, dividing multiples of 4 from 46 until you can't divide anymore. You can't divide anymore because 2 is less than 4. So, 2 is the remainder.

**Answer:**

the x-axis is 0,1

the y -axis is -1, - 35

sorry if im rong

**Step-by-step explanation:**

**Answer:**

look at explanation

**Step-by-step explanation:**

the first thing to do when graphing is to look at your y coordinate, the last number without a variable behind it. this would be (-1).

mark -1 on your graph, which should be one slot to the left of zero.

the slope (the number with the variable behind it) can be read as rise/run. turn -34 into a fraction by simply putting it over 1. this will give you -34/1.

your rise in this case would be -34, which means from -1, go down 34 slots and put a nother dot. your run(denominator in fraction) is where you move horizontally. since the run is 1, move over 1 spot from where your last dot is and that is your final plot. connect the first dot you made tot he third dot you made and you have officially graphed it.

**Step-by-step explanation: [30-24+9]=15-5=10**

The answer after calculation the given **expression** using **PEDMAS**** **rule: [6x(5-3)+9]-5 is 16.

The given **expression**, [6x(5-3)+9]-5, can be simplified using the order of operations, also known as **PEDMAS** P – Parenthesis First: B – Brackets First

E – Exponents

D – Division

M – Multiplication

A – Addition

First, we evaluate the **expression** inside the bracket: 5-3, which equals 2. Substituting this result back into the expression, we have [6x2+9]-5.

For the next **step**, we perform the multiplication operation. Multiplying 6 by 2 gives us 12. Now our expression becomes [12+9]-5.

Moving on to addition, we add 12 and 9, resulting in 21. Our expression now becomes [21]-5.

Finally, we subtract 5 from 21, which gives us 16. Thus, the value of the **expression** [6x(5-3)+9]-5 is 16.

7 1/2 divided by 2 5/8 in simplest form

**Answer:**

[tex]2\frac{6}{7}[/tex]

**Step-by-step explanation:**

First you have to convert the mixed numbers to an improper fraction which first let's do the top so that would be: [tex]\frac{\frac{15}{2}}{2\frac{5}{8}}[/tex]

Next, lets do the bottom of that so that would become: [tex]\frac{\frac{15}{2}}{\frac{21}{8}}[/tex]

After that you have to apply the fraction rule [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex] so that would be: [tex]\frac{15\cdot \:8}{2\cdot \:21}[/tex]

Towards the end, you have to cancel out that equation so then it becomes: [tex]\frac{20}{7}[/tex]

Finally, you convert the improper fractions to mixed numbers so that is now: [tex]2\frac{6}{7}[/tex]
