Graph y= -2x + 5. Help please.

The roots of the equation are imaginary numbers, 5+6i, 5-6i.

A quadratic equation is what can be written in the form of ax²+bx+c=0

The quadratic equation is

x² -10x = -34

x² -10x +34 = 0

The roots formula for a quadratic equation is given by

[tex]x = \dfrac{ -b \pm \sqrt{b^2 -4ac}}{2a}[/tex]

Here a = 1

b = -10

c =  34

The roots of the equation are

[tex]x = \dfrac{ 10 \pm \sqrt{(-10)^2 -4*34}}{2}[/tex]

[tex]\rm x = \dfrac{ 10 \pm \sqrt{-36}}{2}\\\\\\x = 5 \pm 6i[/tex]

Answer:

7/16 of a yard

Step-by-step explanation:

Let's put the boards to the same denominator so it's easier.

Let's go with a denominator of 16

1/4= 4/16

7/8= 14/16

3/16 stays the same.

So, 4/16+3/16+x=14/16

7/16+x=14/16

x=7/16 of a yard, the length of the 3rd board.

Answer:

$3.23

Step-by-step explanation:

Given that,

Principal, P = $2,000

Rate of interest, r = 1.96%

Tie, n = 1 month = (1/12) years

The formula of compound interest is given by :

[tex]CI=P[(1+\dfrac{R}{100})^n-1]\\\\CI=2000\times [(1+\dfrac{1.96}{100})^{1/12}-1]\\\\CI=3.23[/tex]

So, the interest will she earn at the end of 1 month is $3.23

The amount she earns at the end of 1 month is 200,326cents

The formula for calculating the compound amount is given as:

A = 2000(1 + 0.0196/12)^(12*1/12)

A = 2000 (1+0.00163)^1

A = 2000(1.00163)

A = $2,003.26

Hence the amount she earns at the end of 1 month is 200,326cents

Answer:

To determine if two fractions are equivalent, cross multiply. To cross multiply, you multiple the numerator of the first fraction by the denominator of the second. Then you multiply the denominator of the first fraction by the numerator of the second. If the two numbers are equal, the fractions are equivalent

Step-by-step explanation:

given: size of television is height = 37 in,  length = 71 in.

A.  using Pythagorean theorem:

parts given are legs which is the sides

looking for the hypotenuse.

B.  formula:

a² + b² = c²    or   H² + L² = D²

where H = height = 37

           L = length = 71

           D = diagonal (which is req'd)

C.   D² = 37² + 71²

      D = [tex]\sqrt{1369+ 5041}[/tex]

      D = [tex]\sqrt{6410}[/tex]

     D = 80 in (missing length)

D. size of television:

Step-by-step explanation:

Answer:

Divide both sides by a constant to simplify the equation.  Thus the second option.

Step-by-step explanation:

Solve for x:

9 - 10 x = -1

Hint: | Isolate terms with x to the left hand side.

Subtract 9 from both sides:

(9 - 9) - 10 x = -9 - 1

Hint: | Look for the difference of two identical terms.

9 - 9 = 0:

-10 x = -9 - 1

Hint: | Evaluate -9 - 1.

-9 - 1 = -10:

-10 x = -10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -10 x = -10 by -10:

(-10 x)/(-10) = (-10)/(-10)

Hint: | Any nonzero number divided by itself is one.

(-10)/(-10) = 1:

x = (-10)/(-10)

Hint: | Any nonzero number divided by itself is one.

(-10)/(-10) = 1:

Step-by-step explanation:

The sale of the 40 shares of stock A at $225 per share will get Juan ...

  40 · $225 = $9000

The sale of the 150 shares of stock B at $27.25 per share will get Juan ...

  150 · $27.25 = $4087.50

So, the total Juan will receive from the sale of the stocks will be ...

  $9000.00 +4087.50 = $13,087.50

Answer:

Step-by-step explanation:

parallel angles are equal

3x + 21 = 6x - 60

combine similar terms:

3x - 6x = -60 - 21

-3x = -81

x = 81/3

x = 27

now, plugin the value of x=27 back into the equation to get the angle:

= 3x + 21

= 3(27) + 21

= 102

= 6x - 60

= 6(27) - 60

= 102

as you noticed, both values are equal 102 = 102 because its a parallel angles

so the equation is 3x + 21 = 6x - 60

Answer:

[tex]\frac{x-4}{(x+3)(x-5)}[/tex]

Step-by-step explanation:

Since the rational function has vertical asymptotes at -3, and 5, the denominator must equal 0 when x is -3 or 5. Therefore, the denominator must be:

(x+3)(x-5)

Now, to make the x-intercept at (4, 0), the numerator must be equal to 0 when x is 4. Therefore, the numerator must be:

x-4

Therefore, that rational function is:

[tex]\frac{x-4}{(x+3)(x-5_}[/tex]
