Answer:
y = 2.31x + 309.35
Step-by-step explanation:
Whenever you are checking for a best fitting equation you want to check if it has a constant slope. If it does then the relation is linear and super easy.
So, since the t values are increasing by the same amount you want to see if the y values are too. And they are, each population entry is increasing by 2.31, this is the slope.
Also, keep in mind you can caluclate slope with the equation 
here x is replaced by t though.
Now, since we know it's linear and we know the slope we can find the equation with the formula y - y1 = m(x - x1) where again, x is replaced by t and m is the slope 2.31
I am just going to use the first point. so x1 = t1 = 0
y - 309.35 = 2.31(x-0)
y = 2.31x + 309.35
Let me know if there was something you didn't understand.
Answer:
A
Step-by-step explanation:
first, distribute -6 to (2b + 1), giving you -12b - 6, and then on the another side of the equation, distribute -2 to (5 + 4b) giving you, -10 - 8b. now we need to put our coefficients on one side so we will add 8b to each side of the equation, giving us -6 = -10 - 8b + 12b, then we will add 10 to both sides of the equation giving us, 10 -6 = -8b +12b, this gives u 4 = 4b. then, you would solve for b, which equals 1.
Answer:
C. 6 because any answer besides that is too low or too high.
Step-by-step explanation:
110.25 pitches so far- 150 at max. 5.75 pitches per game.
4: 4x5.75 = 23
110.25 + 23 = 133.25
5. 5x5.75 = 28.75
110.25 + 28.75 = 139
6: 6x5.75 = 34.5
110.25 + 34.5 = 144.75
7: 7x5.75 = 40.25
110.25 + 40.25 = 150.50 > which rounds up to 151
