Answer:
<em>The equation of the Parabola</em>
<em>(y - 6 )² = 8 (x -6)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given directrix x = 4
we know that x = h - a = 4
h -a = 4 ...(i)
Given Focus = ( 8,6)
we know that the Focus of the Parabola
( h + a , k ) = ( 8,6)
comparing h + a = 8 ...(ii)
k = 6
solving (i) and (ii) and adding
h - a + h+ a = 8 +4
2 h = 12
h =6
Put h = 6 in equation (i)
⇒ h - a =4
⇒ 6 - 4 = a
⇒ a = 2
<u><em>Step(ii):-</em></u>
<em>The equation of the Parabola ( h,k) = (6 , 6)</em>
<em>( y - k )² = 4 a ( x - h )</em>
<em>(y - 6 )² = 4 (2) (x -6)</em>
<em>(y - 6 )² = 8 (x -6)</em>
<u><em></em></u>
Answer:
$47
Step-by-step explanation:
$120 starting out and he spent $45 + $28 of that $120
so 120-45+28=47
The slope intercept form is 
.
Solution:
Given data: slope = 
and y-intercept = –1
y-intercept means (x, y) = (0, –1)
Equation of a line for slope intercept form: 
Here, 
and 
.
⇒ 
⇒ 
Do cross multiplication.
⇒ 
⇒ 
⇒ 
Divide both sides of the equation by 4.
⇒ 
⇒
Hence the slope intercept form is .
