Use the quadratic formula to solve the equation if necessary round to the nearest hundredth x^2+x-30=0

yaroslaw [1]

Answer:

(x-5)(x+6)=0

Step-by-step explanation:

hehe i doing the smae unit rn.

if a=1 (which it does do ac factoring)

you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.

substitute 1x for -5x + 6x.

group the numbers into pairs and find their gcf's

x(x-5) 6(x-5)

since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.

FINAL: (x-5)(x+6) hope this helps

What is the equation of a line with a slope of -2 that passes through the point (6,8)

kakasveta [241]

Answer:

Step-by-step explanation:

hello :

the point-slope formula is :

y - y_1 = m(x - x_1) the point is A(x_1 , y_1 ) , m : the slope

in this exercice : x_1 = 6 y_1 = 8 m = -2

so : y - 8 = -2(x - 6) ...an equation for this line .

Solving an Absolute Value Equation

Andre45 [30]

Answer:

Solution set = {-12, 12}

Step-by-step explanation:

Start by dividing both sides of the given equation by negative one, to get rid of the negative signs on both sides:

$-\,|-x|=-\,12\\|-x|=12$

Now we consider the two possible cases:

1) The expression inside the absolute value symbol is a positive number, then :

$|-x|=-x\\$

and replacing it in the equation, this becomes:

$|-x|=12\\-x=12\\x=-12$

which is our first answer.

2) The expression inside the absolute value symbol is a negative number, then :

$|-x|=x\\$

and replacing it in the equation, this becomes:

$|-x|=12\\x=12$

which is our second possible answer.

Then the set of solutions is: {-12, 12}

What is the answer to -3/4 (2)(-6) in fraction form

nasty-shy [4]

I'm assuming the question looks like this?

$\frac{-3}{4} (2)(-6)$

If so then the answer should be:

$\frac{-3}{4} (2)(-6)=\frac{-3}{4} (-12)=9$

Hope this helps!
