Answer: (5x2 + 2)(3x – 1)
Step-by-step explanation:
3x² + xy2 – 3xy-y? >> 3x² - xy - y
line 1: = (3x² + xy2)+(-3xy – y?)
ANS 3x² - xy - y 《Correct》
line 2: = x(3x + y2) - y(3x – y2)
ANS 3x² - xy +2y²
line 3: = (x-y) (3x +y?)
ANS 3x² - 2xy - y²
If it incorrect, I'm sorry.
Answer:
If the expression is:
-3x + 12 = -3x + 12, infinite solutions
If the expression is:
-3x + 12 = -3x - 12, no solutions
Step-by-step explanation:
Step 1: Distribute
-3x + 12 = 3x = 12
If both lines have the same slope and same y-int, they are the same line and therefore have infinite solutions.
If both lines have the same slope but different y-int, then they are parallel and therefore have no solutions.

Answer:
Step-by-step explanation:
if center= (h,k)
radius=r
eq. of circle is (x-h)^2+(y-k)^2=r^2
a.
center= (-5,1)
radius=4
eq. of circle is (x+5)^2+(y-1)^2=4^2
b.
center=(5,-1)
radius=4
eq. of circle is (x-5)^2+(y+1)^2=4^2
c.
center=(-5,1)
radius=2
eq. of circle is (x+5)^2+(y-1)^2=2^2
d.
center=(5,-1)
radius=2
eq. of circle is (x-5)^2+(y+1)^2=2^2
