Answer: x=-35/10

              y=-4

Step-by-step explanation:

y = 3/2x +5/4

-2x+8y=-25

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

replace y in second equation with: y = 3/2x +5/4

-2x+8(3/2x+5/4)= -25

-2x+12x+10= -25

10x=-35

x=-35/10

x=-3.5

7+8y= -25

8y=-32

y=-4

Which of the following companies offers the greatest total employment compensation? Company A Gross pay $38,200 Insurance $3,500
spayn [35]

Answer:

Company C offers the greatest total employment compensation.

Step-by-step explanation:

Now we calculate the greatest total employment compensation as follows:

Company A :

Gross pay -      $38,200

Insurance -       $3,500

Paid time off -  $4,100

Total compensation = 38,200 + 3,500 + 4,100 = $45,800

Company B :

Gross pay -                         $39,000

Total employee benefit -   20% of 39,000 (0.20 × 3900) = $7,800

Job expenses -                  $700

Total compensation =  39,000 + 7,800 + 700 = $47,500

Company C :

Gross pay -     $39,900

Insurance -      $3,200

paid time off -  $3,900

Job expenses- $1,000

Total compensation = 39,900 + 3,200 + 3,900 + 1,000 = $48,000

Company D:

Gross pay - $39,400

total employee benefits - 18% of 39,400 (0.18 × 39,400) = $7,092

Total compensation = 39,400 + 7,092 = $46,492

Therefore company c offers the greatest total employment compensation.

Find the real numbers x and y that make the equation true (x+6i)=(3-i)+(4-2yi)​
Ronch [10]

Answer:

x = 7

y = -7/2

Step-by-step explanation:

(x+6i)=(3-i)+(4-2yi)​

First look at the real parts

x = 3 +4

x = 7

Then look at the imaginary part

6i= -i -2yi

6 = -1-2y

Add 1 to each side

6+1 = -2y

7 = -2y

Divide by -2

7/-2 = y
