25x² + 9y² + 72y - 81 = 0
25x² + 9y² + 72y - 81 + 81 = 0 + 81
25x² + 9y² + 72y = 81
25x² + 9(y² + 8y + 16) = 81 + 9(16)
25x² + 9(y² + 4y + 4y + 16) = 81 + 144
25x² + 9(y(y) + 4(y) + 4(y) + 4(4)) = 225
25x² + 9(y(y + 4) + 4(y + 4)) = 225
25x² + 9(y + 4)(y + 4) = 225
<u>25x²</u> + <u>9(y + 4)²</u> = <u>225</u>
225 225 225
<u> x²</u> + <u>9(y + 4)²</u> = 1

The conic section is an ellipse.
Answer: If you are looking for Slope-Intercept form (y=mx+b), It would be...
y=-5.4x+10840.4.
If you are looking for Point-Slope form, it would be...
y=-5.4x+10840.4.
Step-by-step explanation: Write in Slope-Intercept from, y=mx+b.
Point-Slope form : Use the Point-Slope formula, y-y1=m(x-x1) to find the equation of the line.
I hope this helps you out! ☺
Answer:
27
Step-by-step explanation:
a + b = 7
a - b = 3
2a = 10
a = 5
b = 7 - 5
b = 2
3⁵ / 3² = 3³ using law of indices
3³ = 27.
Answer: There are 6046 digits will be written on expansion upto 2015th power.
Step-by-step explanation:
Since we have given that
We have to find the number of digits ,
So,
Since we know that
so,
Hence, there are 6046 digits will be written on expansion upto 2015th power.
So basically you're dividing 12 by 3 times x which is 12 over 3x. 12/3x
