Answer:

x = 10, y = 20

Step-by-step explanation:

Form a system of equations:

From the picture at the bottom you can see that vertical angles are equal, so:

3x + 2y = 70

Then, since the angles all together will add up to 360, you can do

3x+2y+9x+y+70+9x+y=360

21x+4y+70=360

subtract 70 from both sides

21x + 4y = 290

With the equation 3x + 2y = 70, multiply both sides by 2

6x+4y=140

Subtract the two equations:

15x=150\\x=10

Plug this into one of the original equations

30+2y=70\\2y = 40\\y=20

We see it is the y terms squared so it opens left or right

in form
(y-k)^2=4(p)(x-h)
vertex is (h,k)
and p is distance from focus to vertex, also distance from vertex to directix
if p>0, then it opens to the right and dirextix is to the left of vertex
if p<0, then it opens to the left and directix is tothe right of vertex


so
(y-1)^2=4(4)(x-(-3))
vertex is (-3,1)
4>0 so dirextix is to left of vertex
left is in x direction
-3-4=-7
directix is x=-7

Solve the system by graphing: y=-3x-3 and y=2x+2. Make sure you write your answer as an ordered pair: (x,y)
Rainbow [258]

Answer: (5, 12)

Step-by-step explanation:

Just graph the linear equations and find where they intersect.

Algebraically, you can set them equal to each other

-3x-3=2x+2

-x-3=2

-x=5

x=5

Plug x=5 to any equation

y=2(5)+2

y=12

2.) Damian types 110 words in 5 minutes. Howard types 208 words
jekas [21]

Answer:

Step-by-step explanation:

First, divide each persons rate by the number of minutes they typed their words in .

you end up with:

Damian: 55 seconds

Howard: 26 seconds

This tells us that Howard was least and <u>Damian was greater. </u>

Hope this helps :)
