A bakery sells 3642 pastries in 2010. The bakery sells 8422 pastries in 2015. Write a linear model that represents the number y of pastries that the bakery sells x years after 2010
1 answer:
Answer:
y = 936x + 3742
Step-by-step explanation:
If it is a linear model, then we should have a slope and y-intercept with the equation representing the model as;
y = mx + c
where m is the slope and c is the y-intercept
Thus, we have for the slope;
(8422-3742)/(2015-21010) = 4680/5 = 936
So the equation will be;
y = 936x + c
To get c , we can use the years after 2010 which is 2015 in this case
8422 = 936(5) + c
c = 8422- 4680
c = 3742
So the linear model is;
y = 936x + 3742

Y=7x+1 *note that the first number is always the x. so, a) (0,?) y=7(0)+1 y=1 (0,1) b) (3,?) y=7(3)+1 y=21+1 y=22 (3,22)

Step-by-step explanation:
Answer:
n(AUB) = 33
Step-by-step explanation:
U is the 21'st letter of the alphabet so
9 + 1 + 2 + 21 =33
n(AUB) = 33
Answer: y intercept = 4
slope= y = 3.4/2x +4
13 months = 26.6
Step-by-step explanation:
for the slope i used the "straight line ordered pairs and did y2-y1/x2-x1 which is the slope plug in a pair of points into the equation and u got the y intercept then use the euation and plug in 13 into the x place and calculate
