Joan pays 456.25 monthly on her mortgage. If her annual insurance premium is 1,560 and her annual real estate tax is 1,890, what
defon
The combined payment is 743.75.

The annual amount of insurance is 1560.  Dividing this by 12 gives us the monthly amount paid:
1560/12 = 130.

The annual real estate taxes are 1890.  Dividing this by 12 gives us the monthly amount paid:
1890/12 = 157.50

We add these to the monthly mortgage payment to find the total amount:
456.25+130+157.50 = 743.75

What is the value of the function when x = 4?<br><br> y = 3x + 7
adelina 88 [10]

2x - 3y = 7 and -3x + y = 7..multiply Equation 2 by THREE and add to Equation 1
-9x + 3y = 21...........................watch the y's disappear
-7x........ = 28
x = -4
substitute -4 instead of x in either of the ORIGINAL equations

2x - 3y = 7
2(-4) - 3y = 7
-8 -3y = 7..........add 8 to both sides
-3y = 15
y = -5

im not sure

45x+10y+50=?<br> PLZ HELP ASAP DUE TODAY!
Viktor [21]

Answer:

5(9x + 2y + 10)

or

x = 0

y = -5

Step-by-step explanation:

If you are just factoring this, you will factor a 5 out from everything.

5(9x + 2y + 10)

or if you are trying to solve just isolate one of the variables and then substitute it into the original equation

45x + 10y = 50

10y = 50 - 45x

y = 5 - 4.5x

45x + 10(5-4.5x) + 50

45x + 50 - 45x + 50

x=0

45(0) + 10y + 50

0 + 10y + 50

10y + 50

10y = -50

y = -5

and it would be x = 0 and y = -5
