Part a)

for extraneous solution
<span>
1 ⋅ sqrt(x+2) + 3 = 0</span>

for non extraneous solution

1⋅ sqrt(x+2)  + 3 = 6

part b) solve each equation

1⋅sqrt(x+2)+3=0 

x+sqrt(x+2)=−3 

square both sides

(sqrt(<span>x+2)</span>)^ 2 = (−3)^2 


x+2=9 

x=9−2 

x=7 

do you see why its extraneous

Hello there.
<span>
Part 1. Create two radical equations, one that has an extraneous solution, and one that does not have an extraneous solution. Use the equation below as a model.

a√x+b+c=d
</span>
1⋅ sqrt(x+2)  + 3 = 6

What is the y-intercept of the line perpendicular to the line y = 3/4x + 3 that includes the point (-3, -3)
kipiarov [429]
A perpendicular line has an opposite reciprocal slope. This means that the new line will have a slope of -4/3x. Plug in x and y into the equation y=Mx +b where m is the slope (-4/3):
-3=(-3/4)(-3) + b
and isolate b:
b-3=(-3/4)(-3)
b=(-3/4)(-3) +3
b=9/4+3
b=21/4

The final equation is y= -4/3x + 21/4
The y intercept is (21/4).

Please help me with this problem I don't understand how to solve it <br> 1.) Simplify. √18
Citrus2011 [14]
Answer:
3√2 or 4.2426

Explanation:
18 can be written as 9*2
This means that:
√18 can be written as √9 * √2
Now, √9 is equal to 3
So, the simplified form of √18 is 3√2 which is equal to 4.2426 in decimal form.

Hope this helps :)

The submarine is cruising at a depth of 50 meters, then dives 75 meters, then ascends (moves in the direction of the surface )60
sukhopar [10]
Interesting question... let's draw a picture.

50 m ----------
                     \              ----------------------------- \
    75 m down \           / 60 m up      45 m down ------
                        ---------

So what's going on?
Going 75 m deeper: 50 + 75
Coming up 60 m    : 50 + 75 - 60
Going 45 m deeper: 50 + 75 - 60 + 45

Final depth: 110 m
