Answer:

Not a solution

Step-by-step explanation:

y ≥ 2x + 5

=> Substituting x = 2 and y = -1 in Equation,

=> -1 ≥ 2(2) + 5

=> -1 ≥ 4 + 5

=> -1 ≥ 9 [Not possible]

Therefore, (2,-1) is not a solution of y ≥ 2x + 5

45% of $360 is what as a quantity

Bess [88]

I'm assuming you want to know what 45% of 360 is.....

so you multiply 360 by 0.45 (since 45 is a percent, and to revert it back, you must move the decimal 2 times to the left) and you have your answer...

Find the domain of the function.

timurjin [86]

When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.

u(x) ≥ 0.

$\sqrt{9x+27} \geq 0$

9x + 27 ≥ 0 by squaring both sides

9x ≥ -27

x ≥ -3

So the domain of the function is when x ≥ -3 is true.
