Answer = x5+5x4+x3
Step-by-step explanation:
x3(x2+5x+1)
=(x3)(x2+5x+1)
=(x3)(x2)+(x3)(5x)+(x3)(1)
=x5+5x4+x3
Answer = x5+5x4+x3
Answer:
0=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3y−6)=−3(8−4y)
(4)(3y)+(4)(−6)=(−3)(8)+(−3)(−4y)(Distribute)
12y+−24=−24+12y
12y−24=12y−24
Step 2: Subtract 12y from both sides.
12y−24−12y=12y−24−12y
−24=−24
Step 3: Add 24 to both sides.
−24+24=−24+24
0=0
Answer:
f (x) = { 19 + 0.39(x - 300), x > 300
Step-by-step explanation:
Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan. If then If then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore Hence, { 19 + 0.39(x - 300), x > 300
