90 - 40 = 50

Complementary angles add up to 90 degrees.

If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.

The answer would then be 50 degrees.

Solve this quadratic equation by completing the square <br> x^2+6x=18
cestrela7 [59]

Answer:

( x + 3 )² - 27

Step-by-step explanation:

x² + 6x = 18

→ Minus 18 from both sides to get a quadratic equation

x² + 6x - 18

⇒Completed square from is ( x + a )² + b

⇒The value of 'a' will always be half the 'b' value in the equation

ax² + bx + c

→( x + 3 )² + b

Expand out the equation to find 'b'

x² + 6x + 9

We have do something to get from 9 to - 18 which -27

So the answer is ( x + 3 )² -27

Answer:

As shown in picture,

Option 2 is correct.

Horizontal asymptote at y = 0 (graph approaches to 0 when x at -infinity and + infinity)

Option 4 is correct.

Vertical asymptote at x = 6 ( graph goes to infinity when x = 6)

Option 5 is correct.

Vertical asymptote at x = -4 ( graph goes to infinity when x = -4)

Hope this helps!

I need help with numbers 1-4 please if someone could help me
laila [671]
You can use the slope formula or just calculate
\frac{rise}{run}
So for the first problem you run 3 units right and rise 5 units so
\frac{rise}{run}  =  \frac{5}{3}
2. Notice the y axis goes by 2 units.
\frac{ - 10}{4}  =  \frac{ - 5}{4}
3.
\frac{0}{12}  = 0
4.
\frac{2}{0}  = undefined
