Answer:

decimal form

x = 6.5

exact form

x = 13/2

mixed number form

x = 6 1/2

For the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation. The quadratic formula, using square roots, factoring, and completing the square are the four ways to solve a quadratic equation.

It is given that the quadratic equation is,

6x² – 2x + 1 = 0

Apply arithmetic operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:6\cdot \:1}}{2\cdot \:6} \\\\\ \\\ x_{1,\:2}=\frac{-\left(-2\right)\pm \:2\sqrt{5}i}{2\cdot \:6} \\\\\\\ x_1=\frac{-\left(-2\right)+2\sqrt{5}i}{2\cdot \:6},\:x_2=\frac{-\left(-2\right)-2\sqrt{5}i}{2\cdot \:6}\\\ \\\\x=\frac{1}{6}+i\frac{\sqrt{5}}{6},\:x=\frac{1}{6}-i\frac{\sqrt{5}}{6}[/tex]

Thus, for the given quadratic equation 6x² – 2x + 1 = 0, the value of x will be 1/6+i√5/6 and 1/6-i√5/6.

The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex]

Step-by-step explanation:

The given parameters in the figure are;

Angle m∠BAC is congruent to angle m∠FDE

Angle m∠ABC is congruent to angle m∠FED

Therefore, in order to show that ΔABC is congruent to ΔDEF, by the Angle-Side-Angle (ASA) rule of congruency, the additional information is the congruency of the included sides between the given angles as follows;

The additional information to show ΔABC ≅ ΔDEF by ASA is [tex]\overline {AB}[/tex] is congruent to [tex]\overline {DE}[/tex] which can be written as [tex]\overline {AB}[/tex] ≅ [tex]\overline {DE}[/tex].

Answer:

58xH=M

Step-by-step explanation:

here is an example car traveles 58mph how many miles in 3 hours

58x3=174mph

The required equation that represents the number of miles the car traveled in h hours is m = 58h.

Given that,
A car travels at a constant speed of 58 miles per hour. Which equation can be used to find m, the total number of miles the car travels, in h hours is to be determined.

Distance is defined as the object traveling at a particular speed in time from one point to another.

Here,
As, per the question,
Distance = speed × time
From the given,
Distance = m
Speed = 58 mile / hour
Time = h (in hours)
So,
m = 58 × h
m = 58h

Thus, the required equation that represents the number of miles the car traveled in h hours is m = 58h.

#SPJ2

Answer:

Step-by-step explanation:

Step one:

given data

price quotes from Company A

charges= $7

additional charges per hour= $3

let the number of hours be x

and the total be y

the linear function for the total is

y=3x+7

price quotes from Company B

charges= $10

additional charges per hour= $2

let the number of hours be x

and the total be y

the linear function for the total is

y=2x+10

if the total quote is the same , then

3x+7=2x+10

solve for x, collect like terms

3x-2x=10-7

x=3 hours

Answer:

$7.50

Step-by-step explanation:

First, you multiply 3 and $2.50 (because you skate for 3 hours and it's $2.50 per HOUR to skate) 3 x 2.50 is $7.50 plus the flat rate of $5 is $12.50. So, your total altogether would be $12.50. So if you pay that total with $20, you have to subtract 12.50 from 20. 20 - 12.50 is $7.50. Your change will be $7.50. I hope this is correct! So sorry if it isn't!

Answer:

7.5

Step-by-step explanation:

First, you multiply 2.50 x 3. The answer to that is 7.50. Add on the renting skates, that is 12.50. Then, you subtract 12.50 from 20.00. The answer is 7.5.

Answer:

Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker

Step-by-step explanation:

Step one:

given data

cost of sneakers= $60

Required

the cost of the sneaker after the two discounts

Actually, the two percents given are the discount of the sale.

the first discount is

15%= 15/100*60

=0.15*60

=$9

The second is 10% coupon

10/100*60

=0.1*60

=$6

The total discounts = 9+6= $15

The cost of the sneakers= 60-15= $45

Jeremy find the cost of the sneakers by solving for the values of the 10% in dollars and subtracting the dollar amount from the cost of the sneaker

Answer:

D

Step-by-step explanation:

The domain must not let 1/3 x + 2 go less than 0. So equate this binomial to  0 and then use the < or > symbol to indicate what the minimum value is.

1/3 x + 2 = 0      Subtract 2 from both sides

1/3 x = - 2          Multiply 3

3(1/3) x = - 2 * 3

x = - 6

So if x is less than - 6 the binomial will go negative and that is not a permitted value at this level.

So x must be - 6 or bigger.

Let's see what happens when x = - 6

1/3 ( - 6) + 2

-2 + 2

0

That's the minimum value for the domain.

Now try - 9

1/3(-9) + 2

- 3 + 2 = -1

That means you will have √-1 which does not exist in the rational world.

Now try x = 9

1/3 (9) + 2

3 + 2 = 5    which is fine.

So the answer you seek is x ≥ -6

Answer:

5 gift baskets

Step-by-step explanation:

We solve this question using the method of Greatest Common Factor

We are told in the question that She has 20 scented soaps and 15 bottles of bubble bath

Hence, we find the factors of 15 and 20

The factors of 15 are: 1, 3, 5, 15

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 5.

Hence, the greatest number of gift baskets Camilla can make is 5 gift baskets

Answer:

h(x) = (10x - 1)(x + 1)

Step-by-step explanation:

Given

h(x) = 10x²+9x-1

Required

Get its equivalent

To do this, we simply factorize h(x)

We have that:

h(x) = 10x²+9x-1

Expand

h(x) = 10x² + 10x - x - 1

Factorize

h(x) = 10x(x + 1) -1(x + 1)

This gives:

h(x) = (10x - 1)(x + 1)

Hence, the equivalent of h(x) = 10x²+9x-1 is h(x) = (10x - 1)(x + 1)

Answer: h(x) = (x+1) (10x-1)

Answer:

80

Step-by-step explanation:

Answer:

Step-by-step explanation:

let each angle=A

A+A+A=180

3A=180

A=180/3=60°

as the angles are equal so sides are equal.

16+y=46

y=46-16=30

applying sine formula

[tex]\frac{30}{sin z} =\frac{46}{sin~80} \\sin~z=\frac{30}{46} \times ~sin~80=\frac{15}{23} \times sin ~80\\z=sin^{-1}( \frac{15}{23} \times sin ~80) \approx~39.96^\circ \approx40^\circ[/tex]

z+x=60

40+x=60

x=60-40=20°
