Answer:

I think it's D

Step-by-step explanation:

The equivalent equation is (x - 3)² = 17

The equation given is :

x² - 6x = 8

The equation is a quadratic equation

A quadratic equation is an equation that has one variable that is raised to the power of 2.

it is usually in the form : ax² + bx + c = 0  

a, b,c are known numbers

x is unknown

To determine which option is correct, we are to solve for each of the options to see which is correct

1. (x - 6)² = 44

(x -6)(x -6) = 44

x² - 6x -6x + 36 = 44

x² -12x + 36 = 44

x² - 12 = 8

The first option is not correct

2. (x - 3)² = 14

(x -3)(x -3) = 14

x² - 3x -3x + 9 = 14

x² -6x + 9 = 14

x² - 6x = 5

the second option is not correct

3. (x-6)² = 20

(x -6)(x-6) = 20

x² -6x -6x + 36 = 20

x² -12x = -14

the third option is not correct

4. (x - 3)² = 17

(x-3)(x - 3) = 17

x² - 3x - 3x + 9 = 17

x² - 6x = 8

The fourth option is correct

x-30% 0f x=70

x-30/100*x=70

100x-30x/100=70

Answer:

[tex]\boxed {\boxed {\sf a \approx207.35 \ in^2}}[/tex]

Step-by-step explanation:

Since the central angle is given in degrees, we should use this formula to find the area of the sector:

[tex]a=\frac{\theta}{360} \times \pi r^2[/tex]

The central angle is 165 degrees and the radius is 12 inches.

Substitute the values into the formula.

[tex]a= \frac{165}{360} \times \pi (12 \ in)^2[/tex]

Solve the exponent.

[tex]a= \frac{165}{360} \times \pi(144 \ in^2)[/tex]

Multiply all the numbers together.

[tex]a= 207.345115137 \ in^2[/tex]

Round to the nearest hundredth (two decimal places).

The 5 in the thousandth place (in bold above) tells us to round the 4 in the hundredth place up to a 5.

[tex]a \approx207.35 \ in^2[/tex]

The area of the sector is approximately 207.35 inches squared.

Answer:  1 & 3/4

We can write this as [tex]1 \frac{3}{4}[/tex]

============================================

Explanation

Consider this: You have 7 donuts and 4 friends you want to split the donuts with. The question is, how many donuts does each of your friends get?

The number 7 isn't a multiple of 4, meaning 7/4 won't result in a whole number. If you had one more donut, then 8/4 = 2 is a whole number. So that must mean everyone only gets one whole donut plus some leftover amount.

If those 4 friends get 1 whole donut each, then 4*1 = 4 donuts are passed out and 7-4 = 3 are left over. The "1" forms the whole part of the mixed number, while the '3' is the numerator of the fraction. The denominator stays the same at 4.

So we go from the improper fraction 7/4 to the mixed number 1 & 3/4. Each person gets 1 whole donut and then 3/4 of a whole donut

------------

We can write the mixed number 1 & 3/4 as [tex]1 \frac{3}{4}[/tex]. Keep in mind that this expression does not mean 1 times 3/4. Instead, it really is saying 1 + (3/4).

Step-by-step explanation:

Data: $50 to rent the Skate Center

$5.50 for each person who attends

Limit of spending: $300

How many people can attend=x

Step one, Make the equation

$5.50x+$50=$300

Reason: Since we know that amount of people(x) multiplied by $5.50 added to $50 will get us $300, we can make an equation from that. The equation will make the problem simpler to solve.

Step two, Start isolating x by subtracting $50 on both sides

$5.50x+$50-50=$300-50=$5.50x=$250

Reason: Since we have to find x, we have to isolate it. The first step in doing that is subtracting $50 by 50 to get rid of it. However, since what you do to one side, you do to the other, you have to subtract $300 by 50 to get $250.

Step three, Divide by 5.50 on both sides

$5.50x/5.50=$250/5.50=x=45.454545454-

Reason: Since we have to isolate x and 5..50 is being multiplied by x, you have to divide it by 5.50 to get rid of 5.50. What you do to one side, you do to the other so you divide 250/5.50 to get 45.4545454545-.

Since this is a irl problem, you have to round it to 45 people

Answer:

10(x+10)(127)

=1270x+12700

The given expression gives [x] as 2.7.

We have the following equation -

10(x + 10) = 127

Given is -

10(x + 10) = 127

x + 10 = 12.7

x = 12.7 - 10

x = 2.7

Therefore, the given expression gives [x] as 2.7.

Step-by-step explanation:

we are given that

[tex] \displaystyle a_{n} = - 3 \: \cdot a_{n - 1} \\ a_{1} = 45[/tex]

we are already given our first term i.e 45

for second term

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{2- 1} [/tex]

simplify substraction:

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{1} [/tex]

since we have [tex]a_1=45[/tex]

substitute:

[tex] \displaystyle a_{2} = - 3 \: \cdot 45[/tex]

simplify multiplication:

[tex] \displaystyle a_{2} = - 135[/tex]

for third term

[tex] \displaystyle a_{3} = - 3 \: \cdot a_{3- 1} [/tex]

simplify Substraction:

[tex] \displaystyle a_{3} = - 3 \: \cdot a_{2} [/tex]

as [tex]a_2=-135[/tex]

substitute:

[tex] \displaystyle a_{3} = - 3 \: \cdot - 135[/tex]

simplify multiplication:

[tex] \displaystyle a_{3} = 405[/tex]

for forth term

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{4- 1} [/tex]

simplify Substraction:

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{3} [/tex]

substitute:

[tex] \displaystyle a_{2} = - 3 \: \cdot 405[/tex]

simplify multiplication:

[tex] \displaystyle a_{2} = - 1215[/tex]

hence,

the first four terms are 45,-135,405,-1215

Step-by-step explanation:

hence,

the first four terms are 45,-135,405,-1215
