Step-by-step explanation:
10-7 do it yourself and don't vheat
Answer:
B
Step-by-step explanation:
-8+2=-6 and im pretty sure negative of a power is just a regular power so its B
Answer:
(-∞, -6] U [-2, ∞)
Step-by-step explanation:
To solve this, begin by factoring this quadratic equation into its factored form:
x² + 8x + 12 ≥ 0 becomes (x+6)(x+2) ≥ 0.
x = -6, and x = -2 are the zeros of this parabola. Therefore:
(-∞, -6] U [-2, ∞) are the parts of the graph above y = 0 because the graph
opens upward.
** Remember, when the '≥' sign is present, the
square brackets must be used.
Answer: 6x + 15
Step-by-step explanation: The distributive property tells us that if we are given an expression such as 3(2x + 5), we can multiply the 3 by both the 2x and the 5 to get 6x + 15.
My work is also shown below.
First of all, you have to understand

<span> is a square-root function.
</span>Square-root functions are continuous across their entire domain, and their domain is all real x-<span>values for which the expression within the square-root is non-negative.
</span>
In other words, for any square-root function

and any input

in the domain of

(except for its endpoint), we know that this equality holds:
Let's take

<span>as an example.
</span>
The domain of

is all real numbers such that

. Since

is the endpoint of the domain, the two-sided limit at that point doesn't exist (you can't approach

<span>from the left).
</span>
<span>However, continuity at an endpoint only demands that the one-sided limit is equal to the function's value:
</span>
In conclusion, the equality

holds for any square-root function

and any real number

in the domain of

e<span>xcept for its endpoint, where the two-sided limit should be replaced with a one-sided limit. </span>
The input

, is within the domain of

<span>.
</span>
Therefore, in order to find

we can simply evaluate

at

<span>.
