Let consider time on x-axis and temperature ony-axis.
The x-axis starts from “0” corresponds to “8 a.m”.Thus after 4 hours, the time will be “12pm”. So we have two values on x-axis,one is “0” and another “4”.
For x = 0, or time value = 8am, the temperature value= y-axis value = -2
For x = 4, or time value = 12pm, the temperaturevalue = y-axis value = 4
Thus we got two points (0,-2) and (4,4).
Now using slope formula = (y2 –y1) / (x2 –x1)
Slope = (4-(-2)) / (4 -0) = 6/4 = 1.5

Answer:
B. 110
C. 130
D. 180
Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories
Let the calories in one serving of milk be x
Let the calories in one serving of juice be y
Let the calories in one serving of soda be z
Thus, for Joe, equation to show amount of calories is;;
2x + y + z = 530 -----(1)
For Darius, equation to show amount of calories is; ;
x + 2y = 370 ------(2)
For Marian, equation to show amount of calories is;
3x + z = 510 ------(3)
Using matrix calculator online to calculate this 3 equations, we have;
x = 110 calories.

Answer:
the answer is B on ed2020
Step-by-step explanation:
for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.
so you have soda = 180 cal and juice = 130 cal
if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct
