Which expression is equivalent to 3m – 6?
A. 2(2m +2)
B. 3(m – 2)
C. 2(m + 3)
D. 3(3m – 6)
Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope
Answer:
Well I can't do it if you don not show the graph :(
Step-by-step explanation:
Answer:
Let's actually find the line of best fit...
m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)
m=(11*836-130*55)/(11*385-3025)
m=2046/1210
m=93/55
b=(Σy-93Σx/55)/n
b=(55Σy-93Σx)/(55n)
b=(7150-5115)/(55*11)
b=185/55, so the line of best fit is:
y=(93x+185)/55
A) The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.
Which means that those who do not practice at all will win about 3.36 times
B) y(13)=(93x+185)/55
y(13)≈25.34
So after 13 months of practice one would expect to win about 25.34 times.

There are three parts to this problem. Solve each percent word problem and show your setup for each one.
You have r rare coins, consisting of p pennies and n nickels.
1. p is 20% of 190. How many pennies do you have?
2. 190 is 200% of r. How many rare coins do you have?
3. n is 60% of r. How many nickels do you have?
Answer:
1. p=38 pennies. 2 r= 95 rare coins. 3. n=57 nickels
Step-by-step explanation:
1. how you get it is .20 x 190
2. 190/2 =2/3 x r
3. .60 x 95

Hope I Help!
Step-by-step explanation:
−2x+3−4x2+11−15x+2x2−15
=−2x+3+−4x2+11+−15x+2x2+−15
Combine Like Terms:
=−2x+3+−4x2+11+−15x+2x2+−15
=(−4x2+2x2)+(−2x+−15x)+(3+11+−15)
=−2x2+−17x+−1
