Answer:

$- \frac{1}{5} m - \frac{4}{5}$

Step-by-step explanation:

$\frac{2}{5} m - \frac{4}{5} - \frac{3}{5} m \\ \\ = \frac{2}{5} m - \frac{3}{5} m - \frac{4}{5} \\ \\ = \frac{2 - 3}{5} m - \frac{4}{5} \\ \\ = - \frac{1}{5} m - \frac{4}{5} \\$

Consider the graph of the quadratic function. Which interval on the x-axis has a negative rate of change?

Gre4nikov [31]

The average rate of change is defined as:

$AVR = \frac{f(x2)-f(x1)}{x2-x1}$

For AVR to be negative, it must comply with:

$x2 - x1> 0$

$f (x2)$

Therefore, we observe that the interval that fulfills these conditions is the whole interval to the right of the parabola.

Among the options given, this interval is:

1 to 2.5

Answer:

An interval on the x-axis that has a negative rate of change is:

D. 1 to 2.5

(ab^2 x -b^4a^3)^2<br><br> What is the answers

Umnica [9.8K]

Answer:

$\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8$

Step-by-step explanation:

Given the expression

$\left(ab^2\:x\:-b^4a^3\right)^2$

solving the expression

$\left(ab^2\:x\:-b^4a^3\right)^2$

$\mathrm{Apply\:Perfect\:Square\:Formula}:\quad \left(a-b\right)^2=a^2-2ab+b^2$

$a=ab^2x,\:\:b=b^4a^3$

so the expression becomes

$=\left(ab^2x\right)^2-2ab^2xb^4a^3+\left(b^4a^3\right)^2$

$=a^2b^4x^2-2a^4b^6x+a^6b^8$

Thus,

$\left(ab^2x-b^4a^3\right)^2:\quad a^2b^4x^2-2a^4b^6x+a^6b^8$

If the price of a business math text rose to $120 and this was 10% more than the original price what was the original selling pr

kolezko [41]

Step-by-step explanation:

120*10% =12

10% percent *120

= (10/100)*120

= (10*120)/100

= 1200/100 = 12

120 - 12 = 108.00 is original price of math text
