Which of the following is a false statement? Solid substances need different temperature of heat to melt them. All solid substances require the same temperature and heat to melt them. Heat is sometimes necessary to change physical property of an object.

All solid substances require the same temperature and heat to melt them.

Step-by-step explanation:

Depending on the substance, the required heat to melt it changes, and is not the same for every solid.

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 the amount would be $140.62
