Doss [256]2 years ago
6 0

Answer:

  no solution

Step-by-step explanation:

There is no solution to this inconsistent system of linear equations. They describe parallel lines.

__

Adding twice the first equation to the second gives ...

  2(5x +6y) +(-10x -12y) = 2(16) +(25)

  0 = 57 . . . . . . . simplify. False

No values of x and y will make this statement true. There is NO SOLUTION to the system of equations.

Ryan is trying a low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels shown in
nydimaria [60]

Answer:

50

Ryan would like to eat <em>more than</em> 50 carbs per day, but <em>no more than</em> 150 carbs per day.

So, Ryan's total carb intake must be <em>between </em>50 and 150 carbs.

Step-by-step explanation:

So he wants to keep his consumption of carbs between the inequalities:

110

So, let's solve both inequalities.

1)

110

Subtract 10 from both sides:

100

Divide both sides by 2:

50

2)

2x+10

Subtract 10 from both sides:

2x

Divide both sides by 2:

x

So, our inequality is now:

110

Since we solved the equations:

50

Written as a compound inequality, this is:

50

In other words, Ryan would like to eat <em>more than</em> 50 carbs per day, but <em>no more than</em> 150 carbs per day.

So, Ryan's total carb intake must be <em>between </em>50 and 150 carbs.
