Sqrt2(5+sqrt8) = 5sqrt2 +sqrt16 = 4+5sqrt2 so result that choice D. is right sure
Answer: y + 7 = -2/3 (x - 1 )
Step-by-step explanation:
The equation of a line in point - slope form is given as :
= m(
)
Where m is the slope and (
,
) is the given point
substituting the values into the formula , we have:
y - (-7) = -2/3 ( x - 1)
y + 7 = -2/3(x - 1 )
Answer:
x=-5, y=2. (-5, 2).
Step-by-step explanation:
2x+y=-8
3x-5y=-25
------------------
5(2x+y)=5(-8)
3x-5y=-25
-------------------
10x+5y=-40
3x-5y=-25
--------------------
13x=-65
x=-65/13
x=-5
2(-5)+y=-8
-10+y=-8
y=-8-(-10)=-8+10=2
