5.) simplify the following polynomial. -6x3+5x-3-(2x3+4x2-3x+1)

-8x3 - 4x2 + 8x - 4

Step-by-step explanation:

Step-by-step explanation:

-6x^3 + 5x - 3 - (2x^3 + 4x^2 - 3x + 1)distribute thru the parenthesis

-6x^3 + 5x - 3 - 2x^3 - 4x^2 + 3x - 1combine like terms

-8x^3 - 4x^2 + 8x - 4 <===

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
