There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.

What is the slope of the line whose equation is 2x−4y=10 ?
Olenka [21]

solve for y

2x−4y=10  

-2x       -2x      subtract -2x from both sides

-4y = -2x +10

-4            -4    Divide both sides by -4 (coefficient on y)

y = -2/-4x  + 10/-4

y = 1/2x - 5/2


the slope is the number on the x (coefficient)

and its 1/2

Answer:

x = 240 feet

Step-by-step explanation:

It is given that,

The angle of depression is 30 degrees from the bottom of the boat to a  deep sea diver at the depth of 120 ft.

We need to find the distance x the diver must  swim up to the boat. It can be calculate by applying trigonometry as follows :

\sin30=\dfrac{120}{x}\\\\x=\dfrac{120}{\sin30}\\\\x=240\ \text{feet}

So, the distance the diver must swim up to the boat is 240 feet.

kumpel [21]

Answer:

x-2=x x=0

No Solution

x+1=1-x

Cancel   1 on both sides

Subtract   −x from both sides

x+x=0

Simplify x +x  to  2x

2x=0

x=0

Check Answer

x+1=1-x

0+1=1-0

1=1-0

1=1
