Answer:
Step-by-step explanation:
hello :
2x²+12x+2y²−16y−150=0
divide by 2 : (x²+6x)+(y²-8y)-75 =0
(x²+6x+9)-9+(y²-8y+16)-16-75 =0
(x+3)²+(y-4)² =10²
The coordinates of the center are (−3,4), and the length of the radius is 10 units.
Answer:
n=-17
Step-by-step explanation:
8(2n-5)=3(6n-2)
1) Distributive property
16x-40=18x-6
16x−40=18x−6
2) Subtract 16x16x from both sides.
-40=18x-6-16x
−40=18x−6−16x
3) Simplify 18x-6-16x18x−6−16x to 2x-62x−6.
-40=2x-6
−40=2x−6
4) Add 66 to both sides.
-40+6=2x
−40+6=2x
5) Simplify -40+6−40+6 to -34−34.
-34=2x
−34=2x
6) Divide both sides by 22.
-\frac{34}{2}=x
−
2
34
=x
7) Simplify \frac{34}{2}
2
34
to 17
−17=x
8) Switch sides.
x=−17
Hello!
Simplifying an expression is putting in its simplest form.
You do 20 * 5 = 100
Then 100 - 2 = 98
The simplest form of the expression is 98
The answer is 98
