Answer:
all real numbers i think
Step-by-step explanation:
Answer: 11
Step-by-step explanation: m<2 is equal to 42. This also means that 3x+9 is equal to 42.
3x+9=42, solve for x. Subtract 9 from both sides. 3x=33, divide by three to get X isolated. X= 11
Answer:
8
Step-by-step explanation:
3x +2x - 5 = 35 to rearrange makes it easier
then, add 3x and 2x which gives you 5x - 5 = 35
then using addition property of equality (APOE) add 5 to both sides which then cancels out the 5 on the left side of the equation and then add 5 to the right side which makes it 40. Then your equation looks like 5x = 40. then using division property of equality, divide by 5 on both sides and 40/5= 8!
(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1
12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5
y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5
m(r) = m(s) --> são paralelas
Answer:
3.14 or pi
Step-by-step explanation:
the area of a circle = 
where r is the radius of the circle
this is 1/4 of the circle, so it would be 1/4 (pi * r²)
it shows that the radius is 2, so you have
1/4 ( pi * 2²)
= 1/4 ( pi * 4 )
= 1/4 (3.14 * 4)
= 3.14 units²
