Answer:

16

Step-by-step explanation:

Start by adding 9 to both sides, obtaining:  √(x + 9) = 5.

Square both sides, obtaining:   x + 9 = 25.

Subtract 9 from both sides:  x = 16

Note that √(16+9) - 9 = -4, as required.

X - 35 > 15 i need answer IMEDIATLEY
SIZIF [17.4K]

I'm assuming you want us to solve this inequality for x, since the question wasn't too clear on that.

x - 35 > 15

Add 35 to both sides to remove the "-35" on the left side so we can isolate the x

x-35+35>15+35

x>50

The solution to this inequality is x>50. Let me know if you need any clarifications, thanks!

Answer:

They will be picked up at 2 \frac{1}{4} yards above sea level

Step-by-step explanation:

Let us consider sea level as reference and positions above sea level as positive and below sea level as negative.

With respect to this reference,

the position of top most point is +17 \frac{3}{4} yards

and the position of lower most point is -13 \frac{1}{4} yards

⇒ The position of midpoint is \frac{+17 \frac{3}{4} - 13 \frac{1}{4}}{2}

                                              = +2 \frac{1}{4}

∴ <u>They will be picked up at 2 \frac{1}{4} yards above sea level</u>
