Answer:

x = -4.59, -7.41.

Step-by-step explanation:

x^2 + 12x + 34 = 0

(x + 6)^2 - 36 +34 = 0

(x + 6)^2 = 36 - 34 = 2

x + 6 = +/-√2

x =   +/-√2 - 6

x = -4.59, -7.41

Answer:

x = 10, -15

Step-by-step explanation:

We can start right away by dividing both sides of our equation by 5 to get the reduced form [tex]x^2-5x=25[/tex].

To "complete the square," or turn the left side of the equation into something we can factor into a perfect square, it helps to remember that for any binomial x - a:

[tex](x-a)^2=x^2-2ax+a^2[/tex]

To "complete" our square, we'll need to add an a² to either side of the equation. To find a, we can set 5x = 2ax and solve:

[tex]5x=2ax\\5/2=a\\25/4=a^2[/tex]

Let's add that a² to both sides and simplify!

[tex]x^2-5x+\frac{25}{4}=25+\frac{25}{4}\\\\(x-\frac{5}{2})^2=\frac{125}{4}\\\\x-\frac{5}{2}=\pm\sqrt{\frac{125}{4} } \\\\x=\pm\frac{25}{2}-\frac{5}{2}[/tex]

Now we're ready to solve for both value of x:

[tex]x=\frac{25}{2}-\frac{5}{2}=\frac{20}{2} =10\\\\x=-\frac{25}{2}- \frac{5}{2}=-\frac{30}{2} =-15[/tex]

So our solutions are x = 10 and x = -15

Answer: x=1

Step-by-step explanation:

Simplify  2x+x+3 to 3x+3

3x+3=6x

Subtract 3x from both sides.

3=6x-3x

Simplify 6x-3x to 3x

3=3x

Divide both sides by 3.

1=x

Switch both sides

x=1

Answer:

[tex]2 x + x + 3 = 6x : x = 1[/tex]

Step-by-step explanation:

[tex]2x + x + 3 = 6x[/tex]

Add similar elements: [tex]2x + x = 3x[/tex]

[tex]3x + 3 = 6x[/tex]

Subtract 3 from both sides:

[tex]3x + 3 - 3 = 6x - 3[/tex]

Simplify:

[tex]3x = 6x - 3[/tex]

Subtract 6x from both sides:

[tex]3x - 6x = 6x -3 - 6x[/tex]

Simplify:

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

Divide both sides by -3:

[tex]\frac{-3x}{-3} = \frac{-3}{-3}[/tex]

Simplify:

[tex]x = 1[/tex]

Answer:

[tex]25n^{2}[/tex]

Step-by-step explanation:

Answer:

only (-4,0) is a reasonable solution.

Step-by-step explanation:

In order to see which ones are reasonable we need to apply the points to the system and check if they make both equations valid at the same time.

y = -x - 4

y = x² + x - 12

For (-4, 0):

0 = -(-4) - 4 -> 0 = 4 -4 -> 0 = 0 (valid)

0 = (-4)² - 4 - 12 -> 0 =  16 - 16 -> 0 = 0 (valid)

For (-3, -1):

-1 = -(-3) -4 -> -1 = 3 -4 -> -1 = -1 (valid)

-1 = (-3)² -1 - 12 -> -1 = 9 -13 -> -1 = -4 (invalid)

For (2, -6):

2 = -(-6) - 4 -> 2 = 6 -4 -> 2 = 2 (valid)

2 = (-6)² -6 -12 -> 2 = 36 -18 -> 2 = 18 (invalid)

Therefore only (-4,0) is a reasonable solution.

Answer: 5(h + w)

Step-by-step explanation:

Number of visitors = 5

Each of the five visitors purchased:

One hamburger (h) + one bottle water (w)

Expression for the amount of harmburger and bottle water purchased is thus ;

Number of visitors × (number of harmburger per person + Number of bottle water per person)

5 ( 1h + 1w)

5h + 5w = 5(h + w)

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0[/tex]

In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided by 2  only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.

[tex]\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0[/tex]

→ Expand the brackets

[tex]\frac{1}{2} x- \frac{1}{2}-\frac{1}{6}x -\frac{1}{6} =0[/tex]

→ Multiply everything by 12 to make solving the equation easier

6x - 6 - 2x - 2 = 0

→ Simplify equation

4x - 8 = 0

→ Add 8 to both sides to isolate 4x

4x = 8

→ Divide by 4 on both sides to isolate x

x = 2

⇒ We can substitute x = 2 back into the equation to see if the solution is correct, if we get 0 on both sides then x = 2 is correct

[tex]\frac{1}{2} (x - 1) - \frac{1}{6} (x+1) = 0[/tex]

⇒ Substitute in the values

[tex]\frac{1}{2} (2-1)-\frac{1}{6} (2+1) = 0[/tex]

⇒ Simplify

[tex]\frac{1}{2} (1)-\frac{1}{6} (3) = 0[/tex]

⇒ Simplify further

[tex]\frac{1}{2} -\frac{1}{2} =0[/tex]

0 = 0

The solution x = 2 is correct

Answer:

The equation of a circle:

[tex](x+2)^2+(y-3)^2 = 16[/tex]

Step-by-step explanation:

The equation of a circle:

[tex](x-h)^2+(y-k)^2 = r^2[/tex]

(where the center is known as [tex](h,k)[/tex] and the radius, known as [tex]r[/tex]).

-Since you already have the center and the radius, use them for the equation of a circle:

Center: [tex](-2,3)[/tex]

Radius: [tex]4[/tex]

[tex](x+2)^2+(y-3)^2 = 4^2[/tex]

After you have the equation of a circle, simplify the radius by the exponent [tex]2[/tex] :

[tex](x+2)^2+(y-3)^2 = 16[/tex]

So, you have found the equation of a circle.

Answer:

y=-2x-2

Step-by-step explanation:

Answer:Statement for Account B is incorrect.

Step-by-step explanation:

Interest for Account B should be 300 x 1.8% = $5.40

The account B is incorrect. The interest of account B is $5.40.

The crediting of cash flows associated with an investment or deposit is referred to as "simple" interest.

In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.

Given that you deposit $100 in Account A with a simple interest rate of 3.4% and $300 in Account B with a simple interest rate of 1.8%. One year later, you get a bank statement, that shows the interest for Account A is $3.40 and the interest for Account B is $540.00

SImple interest for account A,

SI = ( 100 x 3.4 ) / 100

SI = $3.4

Simple interest for account B,

SI = ( 300 x 1.8 ) /100

SI = $5.4

Simple interest for account B is incorrect.

Answer:

[tex]\frac{79}{12}[/tex] or 6[tex]\frac{7}{12}[/tex] gallons of gas.

Step-by-step explanation:

First, you have to convert both of your mixed numbers into a improper fractions.

2 [tex]\frac{1}{4}[/tex] = 9/4

4 [tex]\frac{2}{6}[/tex]   = 26/6

Second, find the greatest common multiple of the denominators of both. In this case, it would be 12.

Then find the number that the first improper fraction's denominator would be multiplied by to get the GCM.  Multiply both the nominator and the denominator by that number.

4 would need to be multiplied by 3 to get 12. So we multiply 9/4 by 3/3. We would get 27/12.

Repeat that for the second fraction's denominator.

6 would need to be multiplied by 2 to get 12. So we multiply 26/6 by 2/2. We would get 52/12.

Then add both fractions together.

[tex]\frac{27}{12}+\frac{52}{12}[/tex] [tex]=\frac{79}{12}[/tex]

If you need to, simplify.

[tex]\frac{79}{12} = 6\frac{7}{12}[/tex]
