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 }
I think if you do 9.00 + 9.00 to get 18.00 then do 17.00 + 17.00 to get 34.00 then do 41.00 + 41.00 to get 82.00 your answer will be 18.00+34.00+82.00= 134 so that’s your answer. Pls make me the brainliest
Answer:
correct students
-5+2x=15
2x=15+5
2x=20(divided by 2 both sides)
x=10
mistake students
-5+2x=15
-3x=15(divided by - 3 both sides)
x=-5
We know that for this equation, 360 is going to be our total. If the skyway's main span is 30 meters shorter, we will be subtracting 30 from whatever our x value is, as shown here:
360 = x - 30
To solve for x, we must do the opposite of the operation we see. The opposite of subtracting 30 is adding 30. So we must add 30 to both sides of our equation.
360 + 30 = 390
So,
x = 390
This means that the length of the main span of the dames point bridge is 390 meters. <span />
Answer:
A.
Step-by-step explanation:
x-2y=4 has a x-intercept of 4, a slope of 1/2, and a y-intercept of -2. 2x+y=4 has a x-intercept of -2, a slope of 2, and a y-intercept of -4.
