Given system of equations:
2y=4x+20 Eq 1
4y=6x+24 Eq 2
Divide both sides of equation 1 by 2.
y=2x+10
Substitute value of y in equation 2.
4(2x+10)=6x+24
8x+40=6x+24
2x+40=24
2x=-16
x=-8
Put value of x in y=2x+10
y=2(-8) + 10
y=-16+10
y=-6

Answer : (-8,-6)

Factorise completely 2y^2-4y
Serga [27]
To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and -4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y(y-2)

2y^2 - 4y in completely factored form is 2y(y-2)

Sonja [21]

Answer:

The overall change is -$7.00.

Step-by-step explanation:

Finding the overall change causes for adding. Same signs add and keep different signs subtract. -4.25+-2.75=7.00. Therefore, the overall change in price for the two days is -$7.00.

By the end of year 8, demarco and tanya would have to pay a final payout of $120,887. $130,900. $143,152. $154,768.
Lubov Fominskaja [6]

If a person invests $50 in a business and gets a percentage increase of 10%, then he would have $55 as his final payout.

<h3>What is an Investment?</h3>

This refers to the financial activity where a person puts money or an asset into a business or venture to gain profit after a period of time.

Hence, we can see that since your question is incomplete as it does not include the initial amount of both Demarco and Tanya, then a final payout cannot be found.
