Question

what is the simplified form of (4x+2)/(x+5) + (3x+1)/(x+5)?

Answer 1

@mathmale

Answer 2

I see y ou are attempting to combine two algebraic fractions.
We'll need to go back to the concept of LCD.

Can you combine 3/5 + 2/7?

Answer 3

there is already a common denominator. you can simplify the equation to ((4x+2)+(3x+1))/(x+5). then just simplify the top by adding

Answer 4

Can I please just have the answer ,, my brain is friend and I was suppose to finish this by 8

Answer 5

lmfao thats not what this site is for, if you wanted that you should've gone to yahoo answers

Answer 6

i don't see it..and i do learn its just i cant think right nw

Answer 7

the simplified version is (4x+2+3x+1)/(x+5)

Answer 8

just combine the tops like terms

Answer 9

7x-1/x+5

Answer 10

the two is positive, so it makes it 7x+3

Answer 11

other than that its right

Answer 12

thank youu

Answer 13

using a directrix of y = -3 and a focus of (2,1) what quadratic function is created

Answer 16

It's no big deal, but I'd appreciate your posting each new question separately.

if you have a textbook available, I'd strongly suggest that you look up parabolas and especially equations of parabolas based on directrix and focus.

Answer 17

yeah for some reason its not posting..im sorry

Answer 18

I can tell immediately from "directrix y=-3 and focus (2,1) that this is a vertical parabola and that the vertex is just below the x-axis.

What is the distance from the directrix y=-3 to the focus (2,1)?

Answer 19

isn't the formula like y-h - k^2? I know immixing it up

Answer 20

That would be one form of the equation for a parabola (after some corrections), but the one I have in mind is much better suited to the problem y ou're working with.

Answer 21

Please answer my question, above.

Answer 22

hmm lemme see

Answer 23

5!

Answer 24

@mathmale

Answer 25

Mind demonstrating how you got that 5?

Answer 26

located 2,1 on graph then counted to -3

Answer 27

but that doesn't come to 5. Hint: 1 - (-3) = ?

Answer 28

oohh ok 4 thenn

Answer 29

helllo

Answer 30

@mathmale @gavinchoate

Answer 31

I'm sorry; I did reply, but apparently my attempt to post that reply did not succeed.

Given that the distance between the directrix y=-3 and the focus (2,1) is 4,
write the point that represents the vertex. Note that the vertex is precisely half way between the focus and directrix.

Answer 32

are u sure its not 5 ... and the mid is -1,1
