Answer:
I don't get it like you messed up on it
Step-by-step explanation:
To find the average, add up all the numbers then divide by how many numbers there are.
(89 + 40 + 18) / 3 = 147/3 = 49 <== ur average
Domain of a Function is a Set of Values under which the Function is defined or a Set of Values which satisfy the respective Function.
The Given Function is : f(x) =
The Condition for Square Root to be defined is any Expression under it should be Greater than or Equal to Zero.
When Function is a Fraction, it Cannot be defined when the denominator becomes zero. Because when the denominator is zero, the fraction tends to ∞ (because anything divided by zero tends to ∞)
According to Above Conditions Described above, The Given Function is Definable only when the Expression which is under the Square Root is Greater than Zero.
⇒ 2x + 10 > 0
⇒ 2x > -10
⇒ x > -5
In Set Builder Form it is Expressed as { x | x > -5 }
Answer:
<u>Cube of any odd number is odd.</u>
The cube of odd numbers are always odd. A perfect cube does not end with 2 zeroes. The given statement is false. There are perfect cubes like 8 and 1728 that end with 8.
Answer:
(4,5)
Step-by-step explanation:
5x+y=25 equation 1
-3x+2y=-2 equation 2
y=25-5x isolate y from equation 1
-3x+2(25-5x)=-2 substitute y value into equation 2
-3x+50-10x=-2
-13x=-52
x=4
solve for y by inserting x value into either equation.
5x+y=25
5(4)+y=25
20+y=25
y=5
