How to find the answer of passes through (8,-4), slope=1/2

Mathematics
1 answer:
Bas_tet [7]3 years ago

Y=mx + b where b is y intercept and m is the slope. So what we need to do is to plug in the slope and the y and x values from the point. So, -4=1/2 times 8 + b. =-4=4+b. Now let's solve for be. -4-4=-8. b=-8. To verify, 4-8 is -4, so this statement is true. Now let's plug our values. y=1/2x-8. So therefore our answer will be y=1/2x-8.

Answer:

So the final answer is

-8\sqrt{3}

Step-by-step explanation:

Radicals:

In mathematics, a radical expression is defined as any expression containing a radical (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.

The given expression is

-5\sqrt{3} -3\sqrt{3}

Now take common radical out so we will get

\sqrt{3}(-5-3)

Now add the Parenthesis part.

\sqrt{3}(-8)

So the final answer is

-8\sqrt{3}

It's 14.285714%

So, simplified it would be 14.3% because you round the 2 up since theres an 8 behind it.

Y-7=2y (x-1) write the equation in standard form
Hunter-Best [27]
  In order for an equation to be in standard form, the equation has to be in Ax+By=c form, where A is equal to the coefficient of x and B is equal to the coefficient of y, whereas c is just the constant, or the number in the equation that isn't being multiplied to a variable. In this case, you should first distribute 2y into (x-1), and then you should perform inverse operations on terms on both sides of the equation such that one side of the equation will only have terms with x and y in them and the other side of the equation will only be a numerical value. When the equation is like this, then the equation is in standard form.
