Answer:
B
Step-by-step explanation:
The only x,y pair in the table is 4,2
Answer:
A is the most promising answer
Step-by-step explanation:
It was kinda hard but a rational number a number that can be written other people can tell you another answer but my logical guest is A because the pair could be written in fraction sorry if I'm wrong.
Also, remember rational number are numebr that can be converted into a fraction 0.296 can be converted into 37/125
0.9888 can be converted into 618/625

2 and are inverses and
2 × = 1
Answer:
14 cows
46 turkeys
Step-by-step explanation:
If all the animals were turkeys, there would be 120 legs. There are 28 more than that. Replacing a turkey with a cow adds 2 legs, so there must be 14 such replacements.
There are 14 cows and 46 turkeys.
_____
Check
14×4 + 46×2 = 56 + 92 = 148 . . . . legs
14 + 46 = 60 . . . . . . heads
Answer:
3x - 2y = -1
Just so you know, this equation is of a line on a graph. It is in standard form.
Ax+By=C, A and B cannot equal zero and A is greater than zero.
A=3
B=-2
C=-1
As need coordinates for x and y.
Let's make this easy, and begin with x=0
[(3)(0)]-[2y]=-1
-2y=-1
Let's divide both sides by -2 to isolate y...
(-2y)/-2=-1/-2
y=1/2
(0,1/2)
y=0
3x - 2y = -1
[3x]-[(2)(0)]=-1
3x=-1
(3x)/3=-1/3
x=-1/3
(-1/3,0)
For the third, how about x=1...
3x - 2y = -1
[(3)(1)]-2y=-1
3-2y=-1
Let's subtract 3 from both sides...
-3+3-2y=-1-3
-2y=-4
y=2
(1,2)
