Step-by-step explanation:
Answer:
Minus 3 (-3), not +
Step-by-step explanation:
The slope intercept or y-intercept is where the line starts from the center. Since a point on the line starts at 0,-3, you pull the y out from the coordinate, because that is your answer. The line starts at -3.

Answer:
<em>The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given Ellipse 9 x² + 4 y² = 36

⇒ 
<u><em>Step(ii)</em></u>:-
The Major axis lies on y-axis
<em> Foci of the Formula C² = a² -b² = 9-4 =5</em>
<em> C = √5 </em>
The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre
<em>Given ellipse of the foci is lie on Y- axis</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The foci of the given ellipse = (0 ,-√5 ) and ( 0, √5 )</em>
(2x-1)(4x+1) just multiply the terms in the parentesis
Do the following:
2x*4x
2x*1
-1*4x
-1*1
You get:
8x^2+2x-4x-1
Final result:
8x^2-2x-1
$118.4 because 64 • 0.85 = 54.4, 64+ 54.4 = 118.4
