All you have to do is plug in the number for x, and find y. I will write this out as if in that chart you have shown.
x y = 9 - 3x y
_______________________________________
0 y = 9 - 3(0) 9
1 y = 9 - 3(1) 6
2 y = 9 - 3(2) 3
3 y = 9 - 3(3) 0
Hope that helps!!
Answer:
using the y intercept formula
Answer:
5 carnations in each arrangement
Total of 60 carnations used
Step-by-step explanation:
First calculate how many flowers are in each arrangement by dividing the total number of flowers by the number of arrangements:
96 ÷ 12 = 8
Given each arrangement has 3 roses, subtract 3 from 8 to find the number of carnations in each arrangement:
8 - 3 = 5
Therefore, there are 5 carnations in each arrangement
Total number of carnations used = 5 x 12 = 60
Answer:
y = 120x
Step-by-step explanation:
y=mx + b is what we need where m is the slope and b is the y-intercept.
the train travels at about 120km/hour, thus the slope is 120.
y= 120x +b. to find the y intercept plug in any coordinate.
240 = 120(2) +b. you find that the y-intercept is 0.
final equation: y= 120x
