36/4=9 48/3=16 so 9*16=144/2=72 so it is 72 square inches
Answer:
A, y + 3 = 2(x + 2)
Step-by-step explanation:
Point slope form is y -y1 = m(x - x1)
To find the equation for this line, plug in y1, m, and x into the equation.
m = 2
y1 = -3
x1 = -2
y - -3 = 2(x - -2)
Since subtracting a negative changes the sign to a positive, the equation becomes:
y + 3 = 2(x + 2)
This is option A.
x² + y² – 10x + 6y + 18 = 0
x² – 10x + y² + 6y + 18 = 0
x² – 10x + 25 - 25 + y² + 6y + 9 - 9 + 18 = 0
(x-5)² + (y+3)² -16 = 0
(x-5)² + (y+3)² = 16
(x-5)² + (y+3)² = 4²
Center at (5,-3) radius = 4
Part 2
1. Complete the square for x and y
2. Put in the format for a circle. (x-h)² + (y-k)² = r², center at (h,k) with radius = r
Answer:
(15x- 8y)
Step-by-step explanation:
"y2" was replaced by "y^2"
((0-(x2))+9xy)+(((x2)+6xy)-23y2)
15xy - 8y2
= y • (15x - 8y)
