Answer: -77
Step-by-step explanation:
(-7(3)^1/2)(11(10)^1/2)=
-7*11*(3)^1/2 * (10)^1/2=
-77*(3*10)^1/2=
-77(30)^1/2=-77
Answer:
Below in bold.
Step-by-step explanation:
Because the 2 sides marked with the double lines are equal:
5y-1 = 2y+11
3y = 12
y = 4.
Also :
3x-5 + 2(2x+5) = 180
3x - 5 + 4x + 10 = 180
7x = 180 + 5 -10
7x = 175
x = 175/7 = 25.
Answer:
Both lines are not parallel
Step-by-step explanation:
Given as :
Two lines equation are as :
3y - 5x = 9 And y = -
x - 12
First line is now written in eq y = mx + c
Or, 3y = 5x + 9
Or, y =
x + 
So, Slop of this line ( m 1 ) = 
slop of second line ( m 2) is 
∵ The slop of both lines are not equal , so the line are not parallel to each other .
Hence Both lines are not parallel Answer
Answer:
The answer is B.
Step-by-step explanation:
When you reflect (2,5) over the x axis, you get (2,-5).
