√x^2+6x+9 if x<3 Pls help cant solve it

Mathematics
1 answer:
madreJ [45]2 years ago
5 0

Answer:

F(x) < 6

Step-by-step explanation:

\sqrt{(x^2 + 6x +9)} = \sqrt{(x+3)(x+3)} = \sqrt{(x+3)^2\\}

This can be simplified to (x+3) and so if x is less than 3, f(x) is less than 6

Four less than 5 times a number is the same as 26 more than twice the number.
Tju [1.3M]

Answer:

False

Step-by-step explanation:

5x - 4 versus 2x + 26

Imagine x equals 1, then the equations would be:

5(1) - 4 and 2(1) + 26

1 and 28 are not equivalent.

Another example would be x = 6

5(6) - 4 and 2(6) + 26

26 and 38 are not equivalent.

No matter what you replace x with, the expressions are never equal.

Inequality from graph<br> Choose the inequality that represents the following graph.
Marysya12 [62]
The answer would be C. this is because the graph shows an open circle, which means it is NOT “or equal to”, so there shouldn’t be a line under the sign. the arrow is also drawn pointing to the right, meaning x would be GREATER THAN 0.
