Y=mx+b
m=4-1\3-2
3\1
y=3\1x+b
(u can take any of the 2 points.am taking the first one)
4=3\1(3)+b
4=9+b
4-9=b
-5=b
answer=
y=3\1x-5
Answer:
The jelly beans cost $2.25 / pound
The trail mix costs $1.25 / pound
Step-by-step explanation:
Let +a+ = cost/pound of jelly beans
Let +b+ = cost/pound of trail mix
(1) 6a + 2b =16
(2) 3a + 5b =13
Multiply both sides by 2
and subtract (1) from (2)
(2) 6a -2b = -16
(1) -6a -2b = -16
8b=10
b=1.25
and
(1) 6a+2b=16
(1) +3a+b=8
(1) 3a+1.25=8
(1) +3a=6.75
(1) a=2.25
10-6= 4
6x10=60
therefore the answer is 10 and 6.
Answer:
C
Step-by-step explanation:
0.5 red : 1 blue
1 red : 2 blue
1.5 red : 3 blue
2 red : 4 blues
2.5 red : 5 blue
3 red : 6 blue
3.5 red : 7 blue
4 red : 8 blue
(per every half a red, there is one whole blue)
C has 4 red and 8 blue
0.5 red x 8 blue = 4 red
1 blue x 8 blue = 8 blue
