One supplementary angle is 12 degrees less than twice the other. find two supplementary angles.

64° and 116°

Step-by-step explanation:

Supplementary angles sum to 180°

let one angle be x then the other is 2x - 12 ( 12 less than twice the other )

Sum the 2 angles and equate to 180

x + 2x - 12 = 180

3x - 12 = 180 ( add 12 to both sides )

3x = 192 ( divide both sides by 3 )

x = 64

The 2 angles are x = 64° and 2x - 12 = (2 × 64) - 12 = 128 - 12 = 116°

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.
