Step-by-step explanation:
line 1 and 2 : parallel
as line 2 is actually
6x + 2y = 8
2y = -6x + 8
y = -3x + 4
so, they have the same slope (factor of x).
line 1 and 3 : neither
the slopes -3 and 3 are not parallel not perpendicular (90°).
line 2 and 3 : neither
as line 2 is parallel to line 1, it has the same relationship to line 3 as line 1.
Answer:
y = 4 · ½ˣ
Step-by-step explanation:
It passes through the point (0, 4), so:
4 = a · b⁰
a = 4
It passes through the point (2, 1), so:
1 = 4 · b²
1/4 = b²
b = ½
y = 4 · ½ˣ
Answer:
Huh I don’t understand this one but I got you
Step-by-step explanation:
I think the answer would be "I spent 4 hours teaching lessons".
One way to do this is to factor both parts of the fraction (prime factors):-
45 = 3*3*5
243 = 3*3*3*3*3
note that 3*3 is common to both factors
so we can write its as 5 / 3*3*3 = 5/27
