I NEED HELP ASAP WITH WORK SHOWN PLEASE GIVE ME AN ANSWER WITH WORK SHOWN Multiple choice questions The answers are 2.26,1.15,2.99,3.41

Answer:

-1, -4

Step-by-step explanation:

x + y = -5

x×y = 4

=>

x = -5 - y

=> (-5 - y) × y = 4

-5y - y² = 4

y² + 5y + 4 = 0

the solution for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

a = 1

b = 5

c = 4

x = (-5 ± sqrt(25 - 16))/2 = (-5 ± 3)/2

=> x = -2/2 = -1 or x = -8/2 = -4

=> y = 4/-1 = -4 or y = 4/-4 = -1

since the sequence in an addition and multiplication does not make any difference, the two numbers are simply -1 and -4

let the original price be x.

x-20% of x= 75

= x- 0.20x= 75

= 0.8x= 75

= x= 75/0.8

=x= 93.75

Answer: the original price is $93.75

Answer:

z = 5 meters

Step-by-step explanation:

since the area = 25 [tex]m^2[/tex] and the only value is z, we have to multiply a number by itself that will equal  25 [tex]m^{2}[/tex].

z × z = 25 [tex]m^{2}[/tex]

5 × 5 = 25 [tex]m^{2}[/tex]

Answer:

6 units

Step-by-step explanation:

JK + KL = JL

3x + 5x-6 = 4x+2

8x-6 = 4x+2

subtract 4x from each side to get:

4x - 6 = 2

add 6 to each side to get:

4x = 8

x = 2

JK = 3x and x=2 so JK = (3)(2) or 6

The numerical length of JK = 6

What is Line Segment?

" A line segment is a line section that can link two points. "

We know that point K is divide line JL

Given that JL = 4x+2

                 KL = 5x-6

                JK = 3x

So,  Equation is JK+KL = JL

                           3x+5x-6 = 4x+2

                           8x-6 = 4x+2

                            8x-4x = 2+6

                            4x = 8

                              x = 8/4

                             x = 2

So , numerical length of JK = 3x

                                        JK = 3×2

                                         JK = 6

Hence , length of JK is 6

Answer:

mean=6+8+8+9+9+10divided 6 =

Answer:

1.

Step-by-step explanation:

The mean score is (8+6+9+9+8+8)/ 6

= 48/8

= 8.

Deviations from the mean are 0 , -2, 1, 1, 0, 0

Squares of these deviations  are 0, 4, 1, 1, 0, 0

So the variance =  (0 + 4 + 1 + 1 + 0 + 0)/ 6 =  1

Standard deviation = √1 = 1.

Answer:

36

Step-by-step explanation:

f * √g = k

12 * √64 = k

k = ± 96

g = k² / f² = (± 96)² / 16² = 36

Answer:

g = 36

Step-by-step explanation:

Given f is inversely proportional to [tex]\sqrt{g}[/tex] then the equation relating them is

f = [tex]\frac{k}{\sqrt{g} }[/tex] ← k is the constant of proportion

To find k use the condition when f = 12 , g = 64 , then

12 = [tex]\frac{k}{\sqrt{64} }[/tex] = [tex]\frac{k}{8}[/tex] ( multiply both sides by 8 )

96 = k

f = [tex]\frac{96}{\sqrt{g} }[/tex] ← equation of proportion

When f = 16 , then

16 = [tex]\frac{96}{\sqrt{g} }[/tex] ( multiply both sides by [tex]\sqrt{g}[/tex]

16 × [tex]\sqrt{g}[/tex] = 96 ( divide both sides by 16 )

[tex]\sqrt{g}[/tex] = 6 ( square both sides )

g = 6² = 36

Answer:

  d.  AB = 54

Step-by-step explanation:

The triangle is isosceles, so AB = AC.

  (4x +6) = (5x -6)

  12 = x . . . . . . . . . . . . add 6-4x to both sides

Then the length of AB is ...

  AB = 4x +6 = 4(12) +6 = 48 +6

  AB = 54

Answer:

i=3/4

Step-by-step explanation:

Assuming that we are treating "i" as a variable and not the constant "i":

12+2i-i=9i+6

12+i=9i+6

12=8i+6

6=8i

8i=6

i=6/8

i=3/4

Therefore, the equation has only one real solution which is i=3/4
