Y = mx + b is the slope intercept form of a linear equation.
m is the slope and b is the y intercept.
To find the y intercept you want to find the point where the graph crosses the y axis. On this graph you can see that it is 1.
The slope is rise/run. This is 2/1, so slope is 2.
Putting these into the equation we get y = 2x + 1
This is not an option because the answers are in standard form.
Changing to standard form we get 2x - y = -1

Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3
elena55 [62]
Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1
Hope that helps!!

What is the PV of an ordinary annuity with 10 payments of $2,700 if the appropriate interest rate is 5.5%? Group of answer choic
Verizon [17]

Answer:

The PV of an ordinary annuity with 10 payments of $2,700 if the appropriate interest rate is 5.5% is $20,352.

Step-by-step explanation:

P = PMT [(1 - (1 / (1 + r)^{n})) / r]

= 2,700 [(1 - (1 / (1 + 0.055)^{10})) / 0.05]

= 2,700 [(1 - (1 / (1 + 0.055)^{10})) / 0.05]

= 2,700 [(1 - (1 / (1.708)) / 0.05]

= 2,700 [(1 - 0.58)) / 0.05]

= 2,700 [(0.41457) / 0.05]

= 2,700(7.53)

=$ 20,352

A sandwich store charges a delivery fee to bring lunch to an office.

Delivery cost - D

Meatball sandwich cost  - M

One office pays $40.50 for 5 meatball sandwiches.

40.50 = 5M + D

Another office pays $66.50 for 9 meat ball sandwiches

66.50 = 9M + D

A. How much does each meatball sandwich add to the cost of delivery?

D = 40.50 - 5M = 66.50 - 9M

40.50 - 5M = 66.50 - 9M

9M - 5M = 66.50 - 40.50

4M = 26.00

M = 6.50

B. What is the delivery fee

D = 40.50 - 5M = 40.50 - 5(6.50) = 40.50 - 32.50 = 8.00

Check

66.50 = 9M + D = 9(6.50) + 8 = 58.50 + 8.00 = 66.50
