At breakfast, he drinks 237 milliliters. at lunch, he drinks 300 milliliters.
rogelio drinks water at every meal. at breakfast, he
at dinner, he drinks 177 milliliters.
a
estimate the total amount of water rogelio drinks. then, find the actual
int of water rogelio drinks. then, find the actual amount of water he drinks
at all three meals.

Step-by-step explanation:

In order to estimate the total amount of water Rogelio drinks at all three meals, you need to follow these steps:

1. Round 237 milliliters and 177 milliliters to the nearest Tens place.

If the digit in the Ones place is less than 5, you must round down.

If the digit in the Ones place is greater than or equal to 5, you must round up.

Then:

2. Add 240 milliliters, 300 milliliters and 180 milliliters:

In order to  find the actual amount of water Rogelio drinks at all three meals, just add 237 milliliters, 300 milliliters and 177 milliliters. This is:

damm bro the struggle

step-by-step explanation:

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
