Y = mx + n
m = Slope
To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1
y = 2x + 5
ma = 2
D: y = -1/2x + 5
mb = -1/2
ma x mb = -1
2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1
It's true.
Answer: D.
Answer:
Step-by-step explanation:
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.
Answer:
the expression would be: 18x-12y
