Answer:

-54

Step-by-step explanation:

8a + 7b + c = 9

We want -6c, but we have c in the equation so multiply by -6

-6(8a + 7b + c) = 9*-6

-48a -42b -6c = -54

Rearranging the equation

-6c - 48a - 42b = -54

Hello from MrBillDoesMath!

Answer:

Discussion:

2 tens = 2 * 10 = 20

13 ones = 13 * 1 13

=> 2 tens + 13 ones = 20 + 13 = 33

Thank you,

If f(x)=2x^2+(1000/x), find the average rate of change of f(x) from x=a to x=a+h.

galina1969 [7]

Answer:

$\frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ is your average rate of change,

Step-by-step explanation:

average rate of change is

$\frac{f(a+h)-f(a)}{a+h-a}$ , by slope formula

simplify this to get $\frac{f(a+h)-f(a)}{h}$ , which is the definition of the derivative as h goes to 0

$\lim_{h \to 0} \frac{f(a+h)-f(a)}{h}$

since you defined x=a, we can substitute a for x and vice versa to find our derivative.

$\lim_{h \to 0} \frac{(2x^2+\frac{1000}{x+h})-(2x^2+\frac{1000}{x})}{h}$

simplifying

$\lim_{h \to 0} \frac{\frac{1000}{x+h}-\frac{1000}{x}}{h}$ (your average rate of change)
