Michaela and Grace were trying to solve the equation: 4x^2 - 100 = 0
Michaela said, "I'll factor the left-hand side of the equation as (2x + 10) (2x - 10) and solve using the zero
product property."
Grace said, “I'll isolate the x? term by adding 100 and dividing by 4 on both sides of the equation. Then I'll solve
by taking the square root. Whose solution would work ?

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 to your question is c.)   volcanoes built the mountains and earthquakes tore them down.
