(1/3 mile) / (1/4 hour)
= (1/3 ÷ 1/4) mile/hour
= (1/3 · 4/1) mile/hour
= 4/3 mile/hour
The answer is B)4
thank you please?
Parallel lines have the same slope. for example, the two lines y = 6x + 3 and
y = 6x - 5 are parallel because they have the same slope, 6x.
the slopes of perpendicular lines are opposite reciprocals, which means that you would flip the numbers of the fraction and make it negative. for example, the opposite reciprocal of -3x is 1/3x.
also, parallel lines never intersect, whereas perpendicular lines intersect at a 90 degree angle.
therefore, it isnt possible for two lines to be both parallel and perpendicular.
Answer:
x = 1/2
and
y = -1
Step-by-step explanation:
8x + 3y = 1
4x + 2y = 0
Multiply 4x + 2y = 0 by 2
8x + 3y = 1
8x + 4y = 0
8x + 4y = 0 minus 8x + 3y = 1
y = -1
For 8x + 3y = 1 plug in y = -1
8x + 3(-1) = 1
8x - 3 x 1 = 1
8x - 3 = 1
Add 3 to both sides
8x - 3 + 3 = 1 + 3
8x = 4
Divide both sides by 8
8x/8 (cancels out) = 4/8
x = 1/2
I think its either ounces or grams but I'm. not sure
