Answer:
3/4
Step-by-step explanation:
12y-9x=25
We need to get y alone so the equation is in the form
y= mx +b where m is the slope and b is the y intercept
12y-9x=25
Add 9x to each side
12y-9x+9x=9x+25
12y = 9x+25
Divide by 12
12y/12 = 9x/12 +25/12
y = 3/4x +25/12
The slope is 3/4 and the y intercept is 25/12
Distance = 100 m = 100/1000 = 0.1 km speed of train = 50 km/hr speed of horse = 56 km/hr resultant speed = (56 – 50) 6 km/hr time = distance/speed time = 0.1/6 = 1/60 hr = 1 min
Answer: The temperature was high, then it slowly went down as time went by.
Step-by-step explanation:
Answer:
Option D) B and C
Step-by-step explanation:
we know that
To find out the percentage of high school teachers that have a second job, divide the number of teachers that have a second job by the total number of teachers
<em>Survey A</em>
Convert to percentage
<em>Survey B</em>
Convert to percentage
<em>Survey C</em>
Convert to percentage
<em>Survey D</em>
Convert to percentage
Compare the percentages
Surveys B and C have the same percentage
therefore
Surveys B and C show proportional results, because the ratio of the number of teachers that have a second job by the total number of teachers is equal (this number is the constant of proportionality k in a proportional relationship between two variables)
