X=9, y=18
First, solve for y by setting y+14 equal to 3y-22 because since it is a parallelogram, the diagonals are congruent. You should get 18 for y one you solve the equation.
Then, plug 18 into 2y+2 and set that equal to 4x+2 for the same reason as the part, then once you solve for x, you should get 9.

What is the equation of the parabola with focus (-1,-1) and directrix y=1?
Inessa05 [86]

Answer:

B

Step-by-step explanation:

Given focus as (h,k) and directrix as y = mx + b, the equation of a parabola is given as:

\frac{(y - mx - b)^2}{m^2 +1}=(x - h)^2 + (y - k)^2

Hence, from the given focus & directrix, we have:

h = -1

k = -1

m = 0

b = 1

<em>We can plug them into the formula and arrange to get:</em>

<em>\frac{(y - mx - b)^2}{m^2 +1}=(x - h)^2 + (y - k)^2\\\frac{(y - (0)x - 1)^2}{0^2 +1}=(x - (-1))^2 + (y - (-1))^2\\\frac{(y-1)^2}{1}=(x+1)^2+(y+1)^2\\y^2-2y+1=x^2+2x+1+y^2+2y+1\\-2y-2y=x^2+2x+1\\-4y=x^2+2x+1\\y=-\frac{1}{4}x^2-\frac{1}{2}x-\frac{1}{4}</em>

<em />

<em>B is the correct answer.</em>

Two pieces of lengths 13/3 m and 3/5 m are cut off from a rope 15
garri49 [273]

Hello there! ;) The way you solve this type of problem is you must find common denominators. So simplify 13/3= 4 1/3. So we can do 1/3*5/5=5/15. Next we must do 3/5*3/3= 9/15. So add 5/15+9/15= 14/15. And add the 4+ 14/15=          4 14/15. So then you must subtract 15 - 4 14/15= 10 1/15 I believe. I believe 10 1/15 is the remainder of the rope. You might want to check in with someone else though.

Hope I help! :D
