Notice y° and y° and 50°, are all three angles in a flat-line, namely "linear angles", and since a flat-line is always 180°.

$\bf y+y+50=180\implies 2y=180-50\implies 2y=130
\\\\\\
y=\cfrac{130}{2}\implies y=65$

Y= 4x-9 and y=x-3 Also using transitive property

Andreyy89

Y = 4x - 9 and y = x-3 so the two right sides (4x-9 and x-3) must be equal

4x-9 = x-3

Let's solve for x

4x-9 = x-3
4x-9+9 = x-3+9 ... add 9 to both sides
4x = x+6
4x-x = x+6-x ... subtract x from both sides
3x = 6
3x/3 = 6/3 ... divide both sides by 3
x = 2

If x = 2, then y is...
y = 4*x - 9 = 4*2-9 = 8-9 = -1
which can also be found by
y = x-3 = 2-3 = -1

So overall x = 2 and y = -1

We have the ordered pair (x,y) = (2,-1)

Marta invested $5, 425 in the stock market and earned 8.5% interest. How much money will Marta have in her account after one yea

Semenov [28]

Answer:

Future Value= $5,886.13

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,425

Number of periods (n)= 1 year

Interest rate (i)= 8.5% = 0.085

To calculate the future value after one year, we need to use the following formula:

FV= PV*(1+i)^n

FV= 5,425*(1.085^1)

FV= $5,886.13
