Explanation:
<u>Part B</u>:
Draw an open circle at x=5. Shade that portion of the number line that exists to the right of the open circle. The solution set is the shaded portion of the number line.
__
<u>Part C</u>:
Any value from the shaded portion of the number line can be used to check the inequality is true. The value at the open circle, or any value to the left of it can be used to check that the inequality is false. For example, one might use values of -5, 5, and 10. Choosing values that are multiples of 5 can make the arithmetic easier.
<u>x = -5 (expect false)</u>
-2/5(-5) < -2
10 < -2 . . . . False
<u>x = 5 (expect false)</u>
-2/5(5) < -2
-2 < -2 . . . . False
<u>x = 10 (expect true)</u>
-2/5(10) < -2
-4 < -2 . . . . True
Answer: 92.5 inches by 100 inches.
Step-by-step explanation:
1. You know that 1 inch represents 8 feet and the dimensions of the building are 740 feet by 800 feet, therefore, you must apply the proccedure shown below:
2. Then, as you can see, the dimensions of the building on the drawing are 92.5 inches by 100 inches.
we have
Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem
case A)
Multiply by both sides
Divide by both sides
therefore
the case A) is not equal to Fiona's equation
case B)
Multiply by both sides
Divide by both sides
therefore
the case B) is not equal to Fiona's equation
case C)
Multiply by both sides
Divide by both sides
therefore
the case C) is not equal to Fiona's equation
case D)
Multiply by both sides
Divide by both sides
therefore
the case D) is equal to Fiona's equation
<u>the answer is</u>
