Answer:

A-2, B-DNE*, C-3, D-DNE, E-4, F-1

---------------------

The first attachment shows the solutions to A and C.

The second attachment shows the solutions to E and F.

There are no real number solutions to systems B and D.

_____

In general, you can solve the linear equation for y, then substitute that into the quadratic. You can subtract the x-term on the left and complete the square to find the solutions.

(3-x) +12 = x^2 +x

15 = x^2 + 2x

16 = x^2 +2x +1 = (x +1)^2 . . . . add the square of half the x-coefficient to complete the square; next take the square root

±4 -1 = x = {-5, 3) . . . . . identifies the second solution set for system A

(x -1) -15 = x^2 +4x

-16 = x^2 +3x

-13.75 = x^2 +3x +2.25 = (x +1.5)^2

roots are complex: -1.5 ±i√13.75

(1-2x) +5 = x^2 -3x

6 = x^2 -x

6.25 = x^2 -x + .25 = (x -.5)^2

±2.5 +.5 = x = {-2, 3} . . . . . identifies the third solution set for system C

remaining problems are done in a similar way.

_____

* DNE = does not exist. There is no matching solution set for the complex numbers that are the solutions to this.

Write 2/15 as a decimal.

Cloud [144]

If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
$\frac{2}{15} = \frac{x}{10}$

now let's multiply both sides by 10:
$\frac{20}{15} = x$
and simplyfy:
(by dividing the first fraction's elements by 5)
$\frac{4}{3} = x$

change improper fraction into a mixed number
$1\frac{1}{3} = x$

and 1 over 3 is 0.33333...

so the answer is 1.333333 - we can also write it as 1.(3)
