Dividing the 2nd equation by 2 gives y=2x + 3 which is the same as the too
p line. any answer to one of them is obviously an answer to the other so there are infinitely many solutions

What is the area of the figure?
nirvana33 [79]

We can break it into two parts.

-> First, the rectangle on the bottom is made up of 2 feet x 16 feet. The formula for area of a rectangle is length times width, so in this case it is equal to 32 feet

-> Next, the triangle has sides of 10 feet, 10 feet, and 16 feet. We can calculate that the height is 6. The formula for area of a triangle is base times height divided by two, so, \frac{16*6}{2}= \frac{96}{2} = 48 feet

-> Last, we can add the two totals together. 32 feet + 48 feet = 80 feet giving us our final answer of 80 feet². As this answer is not pictured I am going to assume they are not including Heron's formula or other more complex formulas, leading us to the answer of "can't be determined"

Answer:

O can't be determined

Have a nice day! - <em>Note: It depends on the level of your math class for whether the answer "cannot be determined" is correct as it can be determined, just takes more effort than simple one - two-step formulas.</em>

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)

How do you solve this question?
Lady bird [3.3K]

Answer:

\large \boxed{\sf \ \ \ 2x-ln(1-x) \ \ \ }

Step-by-step explanation:

Hello,

for any real x different from 1

\dfrac{3-2x}{1-x}=\dfrac{2-2x+1}{1-x}\\\\=\dfrac{2(1-x)+1}{1-x}\\\\=2\dfrac{1-x}{1-x}+\dfrac{1}{1-x}\\\\=2+\dfrac{1}{1-x}

if f(x)=2x

   f'(x)=2

if g(x)=-ln(1-x)

   g'(x)=\dfrac{-1*-1}{1-x}=\dfrac{1}{1-x}

So antiderivative of

\dfrac{3-2x}{1-x}=2+\dfrac{1}{1-x}

Is

2x-ln(1-x)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

X/2−5=−12<br> I need to know how to get the answer to what X is
QveST [7]

Answer:

-14

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x/2-5=-12

1/2x+-5=-12

1/2x-5=-12

Step 2: Add 5 to both sides.

1/2x-5+5=-12+5

1/2x=-7

Step 3: Multiply both sides by 2.

2*(1/2x)=(2)*(-7)

x=-14
