hola buenos días tío PEDRO de la Mari pero le
Solution
The general form of the equation is y = mx + b, where m is the slope and b is the y-intercept.
Given: m = 8/7 and b = -3
Plugin the given values into the formula.
y = 8/7x - 3
The answer is y = 8/7x - 3
Thank you :)
Answer:
X1= -2 X2=6
Step-by-step explanation:
6. the name is circle x (due to the central point)
7. the diameter is segment WY
8. radius is 1/2 of the diameter so 1/2(15) = 7.5 meters
9. diameter is 2 times the radius so 2(4) = 8 cm
10. segment XW, segment XZ, segment XY
11. arc YW, arc WZ, arc ZY
Alright,
directix is y=something so it opens down or up
we use
(x-h)²=4p(y-k)
the vertex is (h,k)
and p is distance from focus to vertex
if focus is above directix, p is positive
if focus is below directix, p is negative
so we gts
focus=(1,1)
directix is y=-1
1>-1
focus is above
oh, vertex is in middle of focus and directix
so
beteeen (1,1) and y=-1 is, hmm
that is a distance of 2 vertically
2/2=1
1 down from (1,1) is (1,0)
vertex is (1,0)
p=1
so
(x-1)²=4(1)(y-0)
solving for y to get into f(x)=something form
(x-1)²=4y
y=1/4(x-1)²
f(x)=1/4(x-1)²
