Answer:
The Slope= -13/3
y-intercept= (0,5/3)
Step-by-step explanation:
m= change in y/change in x
m= y2-y1/x2-x1
m=6-(-7)/ -1-(2)
m=-13/3
Answer:
i believe the answer is A
Step-by-step explanation:
(y + 4) = -(1)/(3)(x + 1)
distribute -1/3 to (x+1)
(y+4)= -1/3x + -1/3
subtract 4 from each side
y= -1/3x - 13/3
Answer:
$528
Step-by-step explanation:
If cost is proportional to order quantity, the cost for 17+5 = 22 cases of cups will be 22/17 times the cost for 17 cases:
(22/17)($408) = $528
The border will have to be 33b - 8
Step-by-step explanation:
Antoine is making a banner in the shape of a triangle
- He wants to add a decorative border around the edges
- The length of the three sides of the triangle are 9b + 8, 12b - 8 and 12b - 8
We need to find the length of the border
The length of the border is the sum of the lengths of the three sides of the triangle
∵ The length of one side = 9b + 8
∵ The length of another side = 12b - 8
∵ The length of the final side = 12b - 8
- Add the lengths of the 3 sides to find the length of the border
∴ The length of the border = 9b + 8 + 12b - 8 + 12b - 8
- Add like terms
∴ The length of the border = (9b + 12b + 12b) + (8 - 8 - 8)
∴ The length of the border = 33b - 8
The border will have to be 33b - 8
