What is the solution of StartRoot x + 2 EndRoot minus 15 = negative 3?
Brilliant_brown [7]

Answer:

x = 142

Step-by-step explanation:

The problem;

\sqrt{x+2} - 15 = -3

Inverse operations;

\sqrt{x+2} -15 = -3\\                +15     +15\\\\\\\\\sqrt{x+2} = 12\\\\

Now undo the square, by squaring both sides;

\sqrt{x+2} = 12\\.^{2} \\\\\\  \\x+2 = 144

Inverse oeprations;

x + 2 = 144

  -2        -2

x = 142

¡¡¡40 POINTS!!!HELP ASAP!!
Nataly_w [17]
Hi there!

To start, we can use the two points to find the slope using the formula y2-y1/x2-x1. Just sub in the points and solve!

-0.5-0.5/3-(-3)
-1/6
Sub that into the formula y-mx+b for m, and use one of the points for x and y - solve for b and you get your equation. 

y=mx+b
y=-1/6x+b
0.5=-1/6*-3+b
0.5=-0.5+b
0.5+0.5=b
b=1

Therefore your equation is y=-1/6x+1

Hope this helps!
