The time a cake must bake is between 25 minutes and 30 minutes, inclusive.
This means that the cake should bake for a minimum of 25 minutes and a maximum of 30 minutes.
equation?
To represent the baking time of the cake using an equation, we can use the inequality:
25 ≤ baking time ≤ 30
The time a cake must bake is between 25 minutes and 30 minutes, inclusive.
The equation to represent the baking time of the cake would be:
25 ≤ baking time ≤ 30
Solve. 5 < x – 2 < 11
To solve the inequality 5 < x - 2 < 11, we can add 2 to all parts of the inequality:
5 + 2 < x - 2 + 2 < 11 + 2
This simplifies to:
7 < x < 13
So the solution is x is greater than 7 and less than 13.
Which graph shows the solution of 9 – c < 2 or –3c > 15?
To graph the solution to the inequality 9 - c < 2 or -3c > 15, we can graph both inequalities separately and then find the region where either of the inequalities is true.
For the first inequality, 9 - c < 2, we can subtract 9 from both sides to isolate c:
-c < -7
Dividing both sides by -1, we flip the inequality sign:
c > 7
This means that c is greater than 7.
For the second inequality, -3c > 15, we divide both sides by -3, which flips the inequality sign again:
c < -5
This means that c is less than -5.
To graph the solution, we plot an open circle at 7 and shade everything to the right of 7, indicating that c is greater than 7. Then, we plot an open circle at -5 and shade everything to the left of -5, indicating that c is less than -5.
The graph would look like this:
-----------o------------------o------------------
-5 7
The shaded regions indicate the solution to the inequality.
To determine the time a cake must bake between 25 minutes and 30 minutes, inclusive, you need to consider the smallest and largest possible values within that range.
The smallest possible value is 25 minutes, which means the cake should not be taken out of the oven before this time has elapsed.
The largest possible value is 30 minutes, which means the cake should not be left in the oven for longer than this time.
So, the cake must be baked for a duration of time between 25 minutes and 30 minutes, inclusive.
