Find the value of x - y if x = 1000, y = 10, and n = 4.
a. -9000
b. 900
C. 990
d.
9000

990

Step-by-step explanation:

You just said 1000 - 10

B. 990

Step-by-step explanation: If x is = to 1000, then the equation is 1000 - y = ?

If y = 10, then the equation is now 1000 - 10 = ?. This is just simple subtraction so 1000-10 = 990.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

the answer is ! ?
