Answer:
infinite solutions
Step-by-step explanation:
2(4x+1) −5x +2 = 3x+4
Distribute
8x +2 -5x +2 =3x+4
Combine like terms
3x +4 = 3x+4
Subtract 3x from each side
3x-3x+4 = 3x-3x+4
4=4
This is always true, so there are infinite solutions
In general, nCr = n! / r! (n-r)!
Here, 7C3 = 7! / 3!(7-3)!
=7 x 6 x 5 x 4 x 3 x 2 x 1 /3 x 2 x 1 ( 4 x 3 x 2 x 1)
=7x6x5x4 / 4x3x2
=7x5x6x4 / 24
=35x24 / 24
=35
Answer:
H, 4 cards
Step-by-step explanation:
There are ten cards in the deck so you convert the fraction into tenths.
2/5 = 4/10 therefor its 4 cards
Yes those answers are correct
Answer:
or 
The graph in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
or 
so
in this problem we have
y=0.75 when x=4
