Answer:

The solution to the quadratic equations are:

x=3\sqrt{3}i,\:x=-3\sqrt{3}i

Step-by-step explanation:

Consider the provided quadratic equation.

x^2+27=0

Subtract 27 from both sides.

x^2+27-27=-27

x^2=-27

x=\pm \sqrt{-27}

x=\pm 3 \sqrt{3}i    ∴i=√-1

Hence, the solution to the equation are:

x=3\sqrt{3}i,\:x=-3\sqrt{3}i

I need to know what the x and y intercepts are for these problems. if you could show work i would appreciate it.
Tomtit [17]

Answer:

1.

  x = (2,0)

  y = (0,-8)

2.

   x  = (-2,0)

   y  = ( 0, 2)

3.

    x =  ( 4,0)

    y = ( 0, -16)

Step-by-step explanation:

aIll do one equation as an example

f(x) = 4x -8

y = 4x - 8

since its an intercept you know the x, for the y intercept will be zero and vice versa. Its like this cause its on the axis.

So you only need to figure out the y for the y intercept and the x for the x intercept.

- 4x  + y = -8

after changing the equation to standar form you then ignore the x base so, 4x to get the y intercept.

- 4x + y = -8 becomes  y = - 8 then you add the 0 for the coordinate

y = -8 becomes (0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

 y = - 8

(0,-8)

f(x) = 4x -8

y = 4x - 8

- 4x  + y = -8

-4x = -8

x = 2

=<br> Given g(x) = -x +4, solve for x when g(x) = -3.
Aloiza [94]

9514 1404 393

Answer:

  x = 7

Step-by-step explanation:

Put -3 where g(x) is and solve the resulting equation for x.

  g(x) = -x +4

  -3 = -x +4

  x -3 = 4 . . . . . . add x (so we can work with a positive coefficient

  x = 7 . . . . . . . . add 3

1. Find the value of x.<br><br> A. 94<br> B. 76<br> C. 88<br> D. 82
BaLLatris [955]

Answer:

76

Step-by-step explanation:

Angle Formed by Two Chords= 1/2(sum of Intercepted Arcs)

94 = 1/2(x+112)

Multiply each side by 2

2*94 = x+112

188 = x+112

Subtract 112

188-112 =x

76 =x

Find the solutions to the equation
pantera1 [17]

Answer:

What is the function of Y 7?

y=7 is a straight line with zero slope and y-intercept 7 as shown below. Hence its domain (all allowed x-values) is all real numbers, and its range (all allowed y-values) is only 7.

Solve the equation 3x² = 108.
saul85 [17]

Answer:

x = 6

Step-by-step explanation:

First we divide both sides by 3 :

x² = 108 ÷ 3

x² = 36

Now we square root both sides :

x = √36

x = 6

Hope this helped and have a good day
