-9 to the second power will most likely be 81. A negative x a negative equals a positive. Hope this helped.
Answer:
12 x 10 = 120
120 divided by 2 = 60
Formula of a triangle:
B(base) x H(height) x 1/2(basically dividing by 2)
Lines are neither perpendicular nor parallel.
Step-by-step explanation:
Step 1:
In equation 1, Y = 5X + 7
In equation 2, Y = -2X -5
Step 2:
Slope Intercept form Y =mX +c
Where m = Slope
Slope of line 1 = 5
Slope of line 2 = -2
m1 is not equal to m2. Hence it is not parallel.
m1 × m2 is not equal to -1. Hence they are not perpendicular.
