-7-(-6)-(-5)
+6+5
^
+11 -7 = +4 is the answer
The negative 6 and 5 turn into a positive because there is a double negative so you add both and then subtract -7

What is the slope and vertical intercept of y = 6x-2?
Bogdan [553]
Even  function : A function is even if f(-x) = f(x) for all x∈ R

Odd function : A function is odd if f(-x) = -f(x) for all x ∈ R

Check if 6 x -2 is even : false
Check if 6x -2 is odd : false

f(-x) ≠ f(x) and  f(-x) ≠ - f(x) therefore 6x -2 is neither even nor odd

Axis interception points of 6x - 2 :

x  intercepts : (\frac{1}{3} ,0)

y intercepts :(0,-2)

inverse of 6 x - 2 : \frac{x+2}{6}

Graph:

plotting :  y = 6 x - 2

hope this helps!

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?
Dovator [93]

Keywords

quadratic equation, discriminant, complex roots, real roots

we know that

The formula to calculate the <u>roots</u> of the <u>quadratic equation</u> of the form  ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}}{2a}

where

The <u>discriminant</u> of the <u>quadratic equation</u>  is equal to

b^{2}-4ac

if  (b^{2}-4ac)> 0 ----> the <u>quadratic equation</u> has two <u>real roots</u>

if  (b^{2}-4ac)=0 ----> the <u>quadratic equation</u> has one <u>real root</u>

if  (b^{2}-4ac)< 0 ----> the <u>quadratic equation</u> has two <u>complex roots</u>

in this problem we have that

the <u>discriminant</u> is equal to -8

so

the <u>quadratic equation</u> has two <u>complex roots</u>

therefore

the answer is the option A

There are two complex roots
