Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins
Answer:
She can't make you do anything, however if it is a distraction to the class then yeah. I'm assuming it's your math teacher. she can make you take off anything on your head though
Step-by-step explanation:
Answer:
For the first example, the constant of proportionality should be .4 of a mile, meaning that Li can run .4 mile per minute. The equation should be .4x = y. For the second example, it is easy to find the constant of proportionality because it is given, which is 2. The equation to represent this would be 2x = y.
Step-by-step explanation:
The reason why the constant of proportionality is .4 is because I used the ratio from before and compared it to the one needed. I simply turned the ratios into fractions and I cross multiplied before turning it into a equation to solve to find .4 as the constant of proportionality. The equation should be .4x = y because x = the amount of minutes Li ran, and y = the total amount of miles she ran. The reason why the constant of proportionality is 2 in the second problem is because Jennifer is paying 2 per pound, which is the unit rate. If we are looking at the cost per pound, it would mean that 2 is the constant of proportionality. The reason why the equation to represent this would be 2x = y is because x = the amount of pounds, and y = the total amount of money, which represents the situation.
Initial population of 340,000 people
each year the population grows by 4.75%
population after 14 years
The function that best represents the problem will be given by
340000 (1 + 0.0475) ^ 14
the population after 14 years will be
651082
Answer:
205 litres
Step-by-step explanation:
The expression that gives the volume of water in Eduardo's pool (in liters) is:
where m is time, in minutes
After minutes ( minutes), the volume is will be:
= 205 litres
The volume of water in the poll will be 205 litres.
