Step-by-step explanation:
Answer:
The answer to your question is below
Step-by-step explanation:
Data
Center = (0, 0)
Vertex = (13, 0)
Focus = (12, 0)
Process
From the data we know that it is a horizontal ellipse.
1.- Calculate "a", the distance from the center to the vertex.
a = 13
2.- Calculate "c", the distance from the center to the focus
c = 12
3.- Calculate b
Use the Pythagorean theorem to find it
a² = b² + c²
-Solve for b
b² = a² - c²
-Substitution
b² = 13² - 12²
-Simplification
b² = 169 - 144
b² = 25
b = 5
4.- Find the equation of the ellipse
or
To solve this question, we need to write this equation in simplified form.
So, Taking the GCF from 2x³ + 4x² - x,
x is divisible by all of them so our new equation will be,
x ( 2x² + 4x - 1)
Correct option is D.
Hope this helped you.. :)
Answer:
f = 2
Step-by-step explanation:
To get f on one side of the equal sign and the constant terms on the other side, you can add (2.75f-2) to both sides of the equation:
4f = 8
Dividing by the coefficient of f gives the desired result.
f = 2

<em>Check</em>
2 +1.25(2) = 10 -2.75(2)
2 +2.50 = 10 -5.50
4.50 = 4.50 . . . . the answer checks OK
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!
Hope this helps :)
