x is less than or equal to -4 or x is greater than or equal to 5
x <= -4 or x>= 5
There is no intersection of both inequalities when we graph it in number line So, we write the interval notation separately for each inequality
for x<=-4 , x starts at -4 and goes to -infinity because we have less than symbol. Also we have = sign so we use square brackets
Interval notation is (-∞ , -4]
for x>= 5 , x starts at 5 and goes to infinity because we have greater than symbol. Also we have = sign so we use square bracket at 5
Interval notation is [5 , ∞)
Now combine both notation by a 'U' symbol Union
(-∞ , -4] U [5 , ∞)
Answer:
B
Step-by-step explanation:
Area of the shaded region = Area <span>of a square - Area of a circle
</span>
Side of a square = 2r
Area of a square = (2r)² = 4r²
Area of a circle = πr²
Area of the shaded region = 4r² - πr² = <span>r²(4-π)</span>
Answer: it is definitely c. y=3x+2
Step-by-step explanation: solve the first equation and then plug in
Answer:
600 x 60 = 36,000
50 x 50 = 2,500
1,000 x 3 = 3,000
70 x 80 = 5,600
100 x 300 = 30,000
20 x 40 = 800
90 x 90 = 8,100
9 x 900 = 8,100
500 x 300 = 150,000
1,000 x 5 = 5,000
125 - 100
770 - 800
364 - 400
923 - 900
755 - 800
