Answer with explanation:

The system of equation are

1. → x²+y²=6

2. →x² -y=6

Subtracting Equation (2) from equation (1)

→ x²+y² -(x² -y)=6-6

 →y²+y=0

→ y × (y+1)=0

→ y=0 ∧ y+1=0

→ y=0 ∧ y = -1

y=0 gives means,by substituting value of y in equation 2,

→ x² -0=6

→ x²=6

→ x =√6 ∧ x= -√6

Solution Set is =(√6, 0) ,(-√6, 0)

y= -1 gives

→ x² - (-1)=6

→ x²=6 -1

→ x²=5

→x = √5, ∧ x= -√5

Solution Set is =(√6, 0) ,(-√6, 0), (√5, 0) ,(-√5, 0)

Use the equation to complete an algebraic proof that proves the answer is x = 7/6. Write your proof in your journal and upload y
Ivahew [28]

Answer:

x=7/6

Step-by-step explanation:

subtract the 4x from both sides of the equation

(2x+6)-4x=4x-3-4x

find common denominator

(2x+6)/5+(5(-4)x)/5=4x-3-4x

then combine fractions

(2x+6+5(-4)x)/5=4x-3-4x

then multiply the 5&4

(2x+6-20x)/5= 4x3-4x

combine terms

(-18x+6)/5= -3

then multiply everything by 5

-18x+6= -15

subtract the 6 from both sides

-18x= -21

divide -21 by -18

(-21)/(-18)=x

find greatest common multiple (3) and solve

x = 7/6

marissa [1.9K]

On January 31, Jean Marie’s business receives a bill for that month’s utilities in the amount of $500. Jean sets it aside because she does not plan to pay the bill until its due date of February 15. What effect, if any, does this event have on the company’s accounting equation as of January 31?

Solution: The event that Jean does not plan to pay the bill until due date of February 15 must be recorded. Recording this event would increase the liabilities and decrease equity on January 31.
