A. x = 5, y = 6

Step-by-step explanation:

The directions tell you to do steps on the calculator, so I can't explain or show how to use it in the calc. But simply just plug it into the calc as a matrix and do rref.

x= 5, y= 6

Step-by-step explanation:

5x - 4y = 1

4x - 2y =8

Multiply the second equation by -2

-8x + 4y = -16

Add this to the first equation

5x - 4y = 1

-8x + 4y = -16

-3x = -15

Divide by -3

-3x/-3 = -15/-3

x = 5

Now find y

4x -2y = 8

4(5) -2y = 8

20-2y = 8

Subtract 20

-2y = -12

Divide by -2

y = 6

1/5

step-by-step explanation:

the dice has 6 sides and there is only one 5 in a dice.

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.
