Answer:
The third answer
Step-by-step explanation:
Rate of change is slope which is 10 for the first one and you can use rise over run to find slope for the graph
First you want to set this into a fraction, so it would be 18/1 because every number has an imaginery one underneath it. then when you divide a fraction you multiply by the reciprical(the opposite) so it would be 18/1 times 3/1 then you can simply cross mutiply and divide, which you can't so then you simply take 18 times 3 which is 108/1 then you divide 108 divided by 1 which is 108, your answer is 108
rt=d
d = 3 km = 3000 m
t=2 hrs. = 7200 seconds
r= x
r= d/t 3000/7200 = 5/12 m/s = 0.416 m/s = 1.5km/h
hope that answers your question
Step-by-step explanation:
Given (5/3)y = (1/4)x - 3, we rearrange these terms so that the equation appears like Ax + By = C:
-(1/4)x + (5/3)y = -3 This is the equation in "standard form."
We can write an algebra formula so let the number be Y
Y x 75% = 15
Y = 15/75% (aka 15/0.75)
therefore Y = 20
