Take two points
(-3, -1) and (1,2)
Find slope
slope formula: m = y2 - y1 / x2 - x1
m = 2 - (-1) / 1 - (-3) = 2 + 1 / 1 + 3 = 3/4
Substitute one of the points into slope intercept form (y =mx + b) to find the y intercept.
y= mx + b
2 = 3/4(1) + b
2 = 3/4 + b
1.25 = b
So:
y = 3/4x + 1.25
No, the number of cows in the barn is 27. You can get this number by subtracting the 83 cows he has from the 56 that are out of the barn.
83 - 56 = 27
Answer:
13 1/8
Step-by-step explanation:
3/8-(-51/4)
Subtracting a negative is like adding
3/8 + 51/4
get a common denominator
3/8+ 51/4 *2/2
3/8 + 102/8
105/8
8 goes into 105 13 times with 1 left over
13 1/8

Step-by-step explanation:
Answer:
<u><em>3.5 °C</em></u>
Step-by-step explanation:
- To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.
3 x 7 = 21
- Add 21 and 8 together to get the sum of the temperatures in the first 8 days.
21 + 8 =29
- Divide 29 by 8 to get the mean temperature for the first eight days.
29 ÷ 8 = 3.5
3.5 °C
