Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth 5y^2-8y=2

Step-by-step explanation:

First, rewrite the equation (all terms should be in the left side):

In this equation,

Then the discriminant

Then

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.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
