Answer:

A

Step-by-step explanation:

x/y - x/y-1

But remember the fraction with the bigger denometer is the smaller number

x/y is the smaller number

therefore the answer is:

x/y-1 - x/y    or      A

Solve each system by elimination.<br> -4x + 8y = -24<br> 7x - 5y = 24
White raven [17]

Answer:

The solution is the point (2,-2)

Step-by-step explanation:

we have

-4x+8y=-24 -----> equation A

7x-5y=24 -----> equation B

step 1

Multiply by 7 equation A both sides

7(-4x+8y)=7(-24)

-28x+56y=-168 -----> equation C

step 2

Multiply equation B by 4 both sides

4(7x-5y)=4(24)

28x-20y=96 -----> equation D

step 3

Adds equation C and equation D

-28x+56y=-168\\28x-20y=96\\-----------\\56y-20y=-168+96\\36y=-72\\y=-2

Find the value of x

substitute the value of y in any equation

equation A

-4x+8(-2)=-24\\4x=-16+24\\4x=8\\x=2

therefore

The solution is the point (2,-2)

Find all polar coordinates of point P = (6,31°). Plz explain the steps :)
mrs_skeptik [129]
<span>P = (6,31°) is already a polar coordinate.

In the notation (r, </span>α) if you make r negative, it points in the opposite direction. If you add 180° to α you compensate for that.

Therefore (6,31°) = (-6,31°+180°) = (-6, 211°)

However, it is more usual to keep r positive.
