Answer:

B) linear function with a positive rate of change

Step-by-step explanation:

Each increase by 1 m^2 in area produces the same 0.2 kW increase in power, so the relationship between area and power is linear. Since they both go up (or both go down), the "rate of change" is positive. (If it were negative, one would go down when the other went up.)

The best description is that of B.

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

(1, 9) and (-3, 16)

$y_{2} =16\\y_{1} =9\\x_{2} =-3\\x_{1} =1$

^^^Plug these numbers into the formula for slope...

$\frac{16-9}{-3 -1}$

$\frac{7}{-4}$

C. $\frac{-7}{4}$

^^^This is your slope

Hope this helped!

Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

musickatia [10]

Answer:

$(3x^2+5x-8)+(5x^2-13x-5)=8x^2-8x-13$

Step-by-step explanation:

The given polynomials are,

$3x^2+5x-8,5x^2-13x-5$

In polynomial addition and subtraction only like terms can be added or subtracted.

So,

$=(3x^2+5x-8)+(5x^2-13x-5)$

$=3x^2+5x-8+5x^2-13x-5$

$=3x^2+5x^2+5x-13x-8-5$

$=8x^2-8x-13$
