Answer:
<u>B: x < -5</u>
- 2x - 7> x + 8
-3x - 7 > 8
-3x > 15
(switch sign when dividing or multiplying by a negative on opposite sides)
x < -5

Answer:
41.24 cm²
Step-by-step explanation:
Here is the complete question: A 3 cm by 3 cm rectangle sits inside a circle with radius of 4 cm. What is the area of the shaded region?
Given: measurement of rectangle is
Radius of circle is 4 cm.
We can find the area of shaded region by subtracting area of rectangle from area of circle.
First, lets find the area of rectangle
Formula; Area of rectangle=
Area of rectangle=
∴ Area of rectangle= 9 cm²
Now, finding the area of circle.
Formula: Area of circle= (∵ r is radius)
Area of circle=
∴ Area of circle= 50.24 cm²
Next solving to find area of shaded region.
Area of shared region=
Area of shaded region=
∴ Area of shaded region= 41.24 cm²
Answer:
No solution
Step-by-step explanation:
To eliminate is to get rid of one of the variables.
You can choose to either add each term in the equations or subtract each term in the equation.
For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.
Try adding them.
. y - x = 15
<u>+ y - x = 5</u>
2y - 2x = 20 No variables were eliminated.
Try subtracting.
. y - x = 15
<u>- y - x = 5</u>
0y - 0x = 10 All variables were eliminated.
. 0 = 10 This is false.
This system of equations cannot be solved.
Graphically, these two lines would have the same slope and are parallel. The solution to a system is same as the point of intersection. Parallel lines never meet, never intersect, therefore there is no solution.
