What are the roots of Quadra equation below? 2x^2+12x+11=0 Helllppp

Mathematics
1 answer:
valentina_108 [34]3 years ago
6 0

Answer:

x=-2±√14/1 is the answer

Step-by-step explanation:

2x²+12x+11=0

by using quadratic formula

x=(-b±√b²-4ac)/2a

here a=2,b=12,c=11

x={(-12)±√(12)²-4(2)(11)}/2

x=(-12±√144-88)/2

x=-12±√56/2

x=-6±2√14/2

x=-4±√14/2

x=-2±√14/1

i hope this will help you :)

PLEEEEEEEEASE HELP! How the heck do i figure this out!!!?<br> Find m

Here is how you find the answer. 
Do remember that the term Bisect means to cut it in half.
So here it goes.
<span>5x = 3x + 10
5x - 3x = 10
2x = 10
x = 5
Then, substitute the values, so 5*5 or 3*5+10
Then, the answer for each smaller angle is 25.
</span>Remember bisect? so 25 x 2 so the final answer is 50.
Hope this is the answer that you are looking for. Thanks for posting your question!

Through (3, 4) and perpendicular to y = (1/3)x - 3
Oksana_A [137]

Answer:3

Explanation:

Write the standard form of the line that goes through  

(

3

,

1

)

and is perpendicular to  

y

=

−

2

3

x

+

The equation  

y

x

is in slope intercept form

y

=

m

x

+

b

where  

m

= slope and  

b

= the  

y

intercept.

The slope of this line is then  

m

=

−

A perpendicular slope is the opposite sign reciprocal. So, we change the sign of  

−

and switch the numerator and denominator.

Perpendicular slope  

m

=

where  

m

is a point.

The slope is

Write an equation of the line that passes through (18,2) and is parallel to the line 3y-x=-12 .
uysha [10]

Answer:

y = \frac{1}{3}x-4

Step-by-step explanation:

<u>Step 1:  Solve for y in the first equation</u>

3y - x = -12

3y - x + x = -12 + x

\frac{3y}{3} = \frac{x}{3} - \frac{12}{3}

y = \frac{1}{3}x - 4

<u>Step 2:  Determine the important aspects</u>

We know that our line is parallel to the other line that has a slope of 1/3 which means that our slope is also going to be 1/3.  We also know that our line crosses the point (18, 2) which means that we can use the point slope form to determine our equation

Point Slope Form → (y-y_1) = m(x - x_1)

<u>Step 3:  Plug in the information and solve</u>

(y-2) = \frac{1}{3}(x - 18)

y - 2 = \frac{1}{3}x - 6

y - 2 + 2 = \frac{1}{3}x - 6 + 2

y = \frac{1}{3}x-4

Answer: y = \frac{1}{3}x-4
