Answer:
8-1
Step-by-step explanation:
Answer:
(-1,5), (0,4) ,(1,3) ,(3,1) is linear so dont pick it
(-4,-7), (-2,-6), (2,-4), (4,-3) is linear
you know what I'll just say it wait a minute is there like a other option
Step-by-step explanation:
U can tell by graphing them out yourself and if u see a straight line then it linear, and if you see a curved loop then it's non- linear. but I'll do it :)
Lets say x is the smaller number and y is the bigger number.
x + y = 436
x + 134 = y
We can substitute the second equation into the first (substitute x + 134 in for y)
x + (x+134) = 436
2x + 134 = 436
2x = 302
x = 151
We can now plug this back into either formula (i use the second)
151 + 134 = b
b = 285
The 2 numbers are 151 and 285
Answer:
A=80 pounds, B=63 pounds
Step-by-step explanation:
Cost of type A=$4.35 per pound
Cost of type B=$5.80 per pound
Cost of A+ B=$713.40
A+B=143 pounds
A=143-B
QaPa+QbPb=713.40
A*4.35 + B*5.80=713.40
4.35A+5.80B=713.40
Substitute A=143-B
4.35(143-B) + 5.80B=713.40
622.05 - 4.35B + 5.80B=713.40
1.45B=713.40-622.05
1.45B=91.35
B=91.35/1.45
=63
B=63
Recall,
A+B=143
A+63=143
A=143-63
=80
A=80 pounds, B=63 pounds
