<em>Greetings from Brasil...</em>
X = 2 liter container
Y = 3 liter container
the total of containers are:
X + Y = 400
the capacity of the containers is
2X + 3Y = 1100
Assembling the equation system
2X + 3Y = 1100
X + Y = 400 x(-2)
2X + 3Y = 1100
<u>-2X -2Y = - 800 </u>
<h3>Y = 300</h3>
X + Y = 400 so
X + 300 = 400
X = 400 - 300
<h3>X = 100</h3>

<em>Observe que:</em>
<em>1 vasilha de 2L = 1 × 2 = 2L</em>
<em>2 vasilhas de 2L = 2 × 2 = 4L</em>
<em>3 vasilhas de 2L = 3 × 2 = 6L</em>
<em>X vasilhas de 2L = X × 2 = 2X litros</em>
<em>.....</em>
<em>1 vasilha de 3L = 1 × 3 = 2L</em>
<em>2 vasilhas de 3L = 2 × 3 = 4L</em>
<em>3 vasilhas de 3L = 3 × 3 = 6L</em>
<em>X vasilhas de 3L = X × 3 = 3X litros</em>
<em>Logo 2X + 3Y = 1100</em>
<em>Existem X e Y vasilhas que num total sao 400, logo</em>
<em>X + Y = 400</em>
Answer:
Domain: All reals
Inverse:
Step-by-step explanation:
To start, let's find the domain. Nothing is restricted, because (x-1)^2 is always defined, so it is the set of all reals. The inverse can be found by making the equation , then switching all of the x's and y's and solving for y. We will get . Now, take the square root of both sides and then add 1 to both sides to get .
Answer: C
The slope is y = -1/2x
Answer:
152 miles add
all non-fractions =149 then add all fractions (5 miles) so it adds up to 152
