E = expresso
m = muffins
2e + 3m = 10.....multiply by -2
4e + 2m = 12
----------------
-4e - 6m = -20 (result of multiplying by -2)
4e + 2m = 12
------------------add
-4m = -8
m = -8/-4
m = 2....so muffins cost $ 2 a piece <===
4e + 2m = 12
4e + 2(2) = 12
4e + 4 = 12
4e = 12 - 4
4e = 8
e = 8/4
e = 2......so expresso's cost $ 2 a piece <===
Answer:
9/14
Step-by-step explanation:
(3/7)/(2/3) Flip the sign of the second term and multiply.
(3/7)*(3/2)
Slope formula: m =
(Knowing that m represents the slope)
Substitute (1,0) for (x1,y1), and (-1,-3) for (x2,y2)
Slope of the line of (1,0) and (-1,-3) is:
m =
=
=
(Simplify)
Slope of the line of (1,0) and (-1,-3) is
