Answer:
y=15
Step-by-step explanation:
y=mx+b
slope(y2-y1)/(x2-x1)
(15-15)/(6-13)
0/-7=0
y-intercept 15=0(15)+b
b=15
y=15
Answer:12,000
Step-by-step explanation:
.05*30,000=1,500
1,500*12=18,000
30,000-18,000=12,000
If $0.35=1 ounce
?=8.5 ounces
8.5/1*$0.35=$2.975 Therefore 8.5 ounces cost $2.975
If 1 ounce =$0.35
12.2 ounces=?
12.2/1*$0.35=$4.27
Therefore 12.2 ounces cost $4.27
Answer:
10x + 6y
Step-by-step explanation:
Let t = length of the third side
3x + 4y + 5x - y + t = 18x + 9y
8x + 3y + t = 18x + 9y
t = 10x + 6y
