Simplify: 5x⁴

(3x⁵– 8x²)

Step-by-step explanation:

15x⁹ - 40x⁶

Step-by-step explanation:

5x⁴ (3x⁵– 8x²)

apply the distributive law: a(b - c) = ab - ac

a = 5x⁴ , b = 3x⁵ , c = 8x²

= 5x⁴ * 3x⁵– 5x⁴ * 8x²

= 15x⁹ - 40x⁶

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.
