find equations of the lines that passe through the given point and are parallel to and perpendicular to the given line Y +4 =0 (
True [87]

Answer:

y = 3 and x = - 6

Step-by-step explanation:

y + 4 = 0 ( subtract 4 from both sides )

y = - 4

this is the equation of a horizontal line, parallel to the x- axis.

a parallel line will also be horizontal with equation

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 6, 3 ) with y- coordinate 3 , then

y = 3 ← equation of parallel line

a line perpendicular to the given line will be a vertical line with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (- 6, 3 ) with x- coordinate - 6 , then

x = - 6 ← equation of perpendicular line

Can anyone help me with this one? i don't understand this worksheet at all.

12^-6/12^7


When dividing the only thing you do is subtract the exponents from each other.

-6-7

In this case, you have to subtract a number from a negative. -6-7 would actually be -6+-7.

-6+-7= -13

12^-13 is the final answer

Answer:

Using Math Papa Algebra Calculator I was able to simplify to:

-81x^5+1198x^3-896x=0

In further detail this equation can be factored and then solved for the multiple x-values given, which are: x=0 or x=−3.7416573867739413 or x=3.7416573867739413 or x= -8/9 or x=8/9

Step-by-step explanation:

I used a punnet square to solve for the simplified equation, from there I used Math Papa Algebra Calculator.

I would answer with the simplified answer, sorry I'd need more specifics to answer this question fully.

Once again the simplified is -81x^5+1198x^3-896x=0
