35 Degrees. This is because the a straight line is 180 degrees. Knowing this, 180-100= 80. 80+65= 145. 180-145=35 which is the missing angle.

-2(4x+4)-3x-2=34 what's the answer

Julli [10]

Answer:

x = -4

Step-by-step explanation:

Given: -2(4x + 4) - 3x - 2 = 34

To solve this equation, we have to isolate the variable. (Get x by itself).

We'll follow the PEMDAS rule as far as parentheses.

So, -2(4x + 4) - 3x - 2 = 34

= -8x - 8 - 3x - 2 = 34

Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.

Hence:

-8x - 8 - 3x - 2 = 34

+8 +2 +8 +2

-8x - 3x = 34 + 8 + 2

Now, we'll simplify.

-11x = 44

Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.

-11x = 44

-11

x = -4

What are the key features of a graph of a quadratic equation with only complex solutions

dybincka [34]

Answer:

If D< 0, the roots of the quadratic equation will b complex.

Step-by-step explanation:

Let $ax^{2} + bx + c =0$ is the given quadratic equation.

So, if the Discriminant (D) = $b^{2} - 4ac < 0$ , the the equation will have only complex solutions.

Complex roots are represented in the form of $(x \pm iy)$

1. x represents the X axis (real) co ordinate,

y represents the Y axis (imaginary) coordinate

2. Also, the graph of the with equation D < 0 NEVER CROSSES the X - axis, as there are no real roots of the equation, only complex roots.

3. Here. roots are always identical but are opposite in signs. Such pair or roots with opposite sign are called CONJUGATE PAIRS.
