Answers

Answer:

4, 16, -4, 2, -1

x = 4±√(16-4(2)(-1)/4

Correct expression:

Step-by-step explanation:

Given the expression

2x² - 8x - 7 = -4x - 6

Rewrite in standard form

2x² - 8x + 4x - 7 + 6 = 0

2x² - 4x  - 1 = 0

Get the coefficients

Given the standard form ax^2 + bx + c = 0

ax^2 = 2x^2

a = 2

bx = -4x

b = -4

c = -1

Use the general formula to find the factors

x = -b±√b²-4ac/2a

Substitute the coefficients

x = -(-4)±√(-4)²-4(2)(-1)/2(2)

x = 4±√(16-4(2)(-1)/4

Hence the values are 4, 16, -4, 2, -1

Can I have the brainliest please?

Answer:

a = -5

Step-by-step explanation:

When you're solving a question like this, your aim is to get the unknown (in this case 'a') by itself on one side of the equation. You do this by adding/subtracting/multiplying/dividing, whatever is necessary for the question. Note that if you do something to one side of the equation, you must do the same to the other.

6-3a=21

First let's get rid of the 6: subtract 6 from both sides.

6-6-3a=21-6

-3a=15

Now let's get rid of the -3: divide both sides by -3.

-3a=15

-3a/-3 = 15/-3

a= -5

11.1.21 A survey​ asked, "How many tattoos do you currently have on your​ body?" Of the males​ surveyed, responded that they had at least one tattoo. Of the females​ surveyed, responded that they had at least one tattoo.

Interpret the interval. Let represent the proportion of males with tattoos and represent the proportion of females with tattoos. Find the ​% confidence interval for . The lower bound is nothing. The upper bound is nothing. ​(Round to three decimal places as​ needed.)

Answers

Complete question :

The Harris Poll conducted a survey in which they asked, "How many tattoos do you currently have on your body?" Of the 1205 males surveyed, 181 responded that they had at least one tattoo. Of the 1097 females surveyed, 143 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval.

Answer:

(−0.0085 ; 0.0481)

Step-by-step explanation:

Given that :

n1 = 1205 ; x1 = 181 ; n2 = 1097 ; x2 = 143 ; α = 95%

Zα/2 = 1.96 ( Z table)

Confidence interval : (p1 - p2) ± E

E =Zα/2 * √[(p1q1/n1) + (p2q2/n2)]

p1 = x1 /n1 =181/1205 = 0.1502

q1 = 1 - p1 = 1 -0.1502 = 0.8498

p2 = x2/n2 = 143/1097 = 0.1304

q2 = 1 - p2 = 1 -0.1304 = 0.8696

E = 1.96 * √(0.0001059 + 0.0001033)

E = 0.0283

p1 - p2 = 0.1502 - 0.1304 = 0.0198

Lower boundary = 0.0198 - 0.0283 = −0.0085

Upper boundary = 0.0198 + 0.0283 = 0.0481

(−0.0085 ; 0.0481)

Answers

Answer:

x = 1

Step-by-step explanation:

x - 3 + 3x = 1

4x - 3 = 1

4x = 4

x = 1

Answer:

x=1, y=-2

Step-by-step explanation:

According to the substitution property, if x = y, then x can be substituted for y in any equation, and y can be substituted for x in any equation.

We are already given the values:

y=x-3

y+3x=1

We can substitute y into the equation.

As so-

[tex]x-3+3x=1[/tex]

Combine common terms:

[tex]4x-3=1[/tex]

Now solve for x. To solve for a variable, we must isolate it:

Add 3 to both sides:

[tex]4x=4[/tex]

The last thing, 4 is being multiplied to x, so we must divide it to both sides to isolate the variable.

[tex]x=1[/tex]

Now we can just substitute the x value into the y equation:

[tex]y=x-3\\y=1-3\\y=-2[/tex]

It is always better to check our answers, we can substitute our x and y into the equation:

[tex]-2+3(1)=1\\-2+3=1\\1=1[/tex]

We are right! :)) Hope it helps!
