And if you mark them on a graph you could see these two are opposite of each other.
Answer:
The slope is 1/3
Step-by-step explanation:
8 – 5 = 3
_____________
7 – -2 = 9
3/9=1/3
Answer:
Step-by-step explanation:
The answer is A
Step-by-step explanation:
x - y + 5z = 29
y + 2z = 4
z = 7
since z = 7 we can use this value in second equation
y + 2×7 = 4 and y = -10
now we know the value of y we can solve the first equation
x -(-10) + 5×7 = 29
x + 10 + 35 = 29
x = -11
Answer:
So the corect answer is (51)
