Answer:
y = mx + b
-1 = 2/5(-3) + b
-1 = -6/5+b
-1 + 6/5 = -6/5 + 6/5 + b
1/5 = b
y = 2/5x + 1/5
Step-by-step explanation:
- write down the slope-intercept form formula
- identify your x and y of the point
- replace x and y by the point
- multiply m and x
- do addition to get b
- write down the equation by replacing m and b with their values
Lets break this down. One minute is 60 seconds, so to find out what 3/4ths of a minute is we would divide 60 by 4 and that would give us 15; but thats only 1/4th of a minute. So to get 3/4ths we take the 15 and multiply that by 3 and we get 45. So if Tim can write 30 words in 45 seconds then he is writing about 0.6 words a second. We repeat that process for Justins words per second and we get 0.6 once again. we then add 0.6 and 0.6 together to get they're combined words per second and we come up with 1.3. Stay with me were almost done! Now we know that together Justin and Tim write 1.3 words a second so if we multiply 1.3 by 60 we now know that combined they write 78 words a minute now we multiply that by 5 and we see that altogether in 5 minutes they write about 390 words.
Answer:
$23.40
Step-by-step explanation:
You have to subtract $39.75 by $16.35 as $39.75 is the total and we have to find out how much the bracelet is. There is also no regrouping.
