Answer:
Center: 2, -3
Radius: 7
Step-by-step explanation:
The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.
The radius is equal to the square root of the constant on the other side.
The square root of 49 is 7.
Answer:
3 = 3(x² - 1) We know, any Function f(x) decrease s in interval [a, b] when f'(x) < 0 ... -1 < x < 1. Hence, function f(x) = x³ - 3x - 2 , is decreased in (-1, 1).
Steps:
1. Multiply what is in the parentheses
5x + 5 = 5x + 2
2. Subtract 5x on each side
3. 5=2
4. 5 doesn't equal 2 so the equation doesn't have a solution or it is not true.
Answer: shade 85 squares
Step-by-step explanation:
34/40
convert that to a percentage
it will be 85%
there are 100 squares in the grid , so you shade 85 of them
