Answer:
Step-by-step explanation:
focus (1 , -7) ⇒ a = 1 & b = -7
y = 1 ⇒ c = 1
Equation of parabola :
(x - a)² + (y - b)² = (y - c)²
(X - 1)² + (y + 7)² = (y - 1)²
Now, expand.
x² - 2x + 1 + y² + 2*7*y + 7² = y² - 2*y*1 + 1
x² - 2x + 1 + y² - 14y + 49 = y² - 2y +1
x² - 2x + 1 + y² - 14y + 49 - y² + 2y - 1 = 0
x² - 2x + <u>y² - y²</u> <u> - 14y + 2y</u> <u>+ 1 + 49 - 1 </u>= 0
x² - 2x - 12y + 49 = 0

im not sure sorry
Step-by-step explanation:
They are same side interior!! Not alternate, they’d be on opposite sides of the line
Well, you will start with the stickers. 5 * 25 = 125, so she will have 125 stickers. Next, she will have 3 boxes of markers, with 12 in each, so she will have 26 markers. If she gets 8 stickers from a friend, she will have 125 + 8 = 133. She will have the same number of markers still.
