Okay, so as you know, the question starts off as this:

9x^3 + 2x^2 -5x +4 -(5x^3 -7x +4)
Distribute the negative:
9x^3 + 2x^2 -5x +4 -5x^3 +7x -4
Combine like terms:
9x^3 -5x^3 +2x^2 -5x +7x +4 -4
4x^3 +2x^2 +2x

You can either end it there or
Divide by x:
4x^2 +2x +2

Answer:

d/c = 8

Step-by-step explanation:

f(x) = 5.4321×2^×

f(4) = 5.4321×2^4 = d

f(1) = 5.4321×2^1 = c

d/c = (5.4321×2^4)/(5.4321×2^1) = 2^3 = 8

A refreshment stand makes 7 large servings of frozen yogurt from 9 pints. Graph the
amm1812

Answer:

y = (7/9)x

Step-by-step explanation:

The equation of a straight line is given as y = mx + b, where y and x are variables, m is the rate of change = change in y / change in x, while b is the y intercept (value of y when x = 0).

When no pint is used, there is no frozen yoghurt. But from 9 pints, 7 large servings of frozen yogurt is made. Let x represent the number of pints and the y represent the number of servings.

Hence, using y = mx + b, we get b = 0, because at 0 pint there is no servings. The equation be comes y = mx

m = change in y / change in x = 7 servings / 9 pints

m = 7/9

The equation is:

y = (7/9)x

Use the commutative property of addition to write an expression equivalent to the following.
defon
<h3>Answer:  b+5a</h3>

Explanation:

The commutative property of addition is where we can add two numbers in any order.

The general equation is x+y = y+x

A more concrete example would be something like 2+3 = 3+2 since both sides simplify to 5.

For 5a+b, it is the same as b+5a. We swap the two terms.
