Answer:
-1/3
Step-by-step explanation:
y = 3x+7
This is in the form y = mx+b
The slope is m so it is equal to 3
Perpendicular lines have slopes that are negative reciprocals
m perpendicular = - (1/3)
Answer:
x= -1, y = 6, z = 3
Step-by-step explanation:
let me solve it with Gaussian Elimination
The answer for that one is B, because 26<54
meaning 26 is less than 54 which is true
