Answer:

$-2x - h - 3$

Step-by-step explanation:

Step 1: Define

Difference Quotient: $\frac{f(x+h)-f(x)}{h}$

f(x) = -x² - 3x + 1

f(x + h) means that x = (x + h)

f(x) is just the normal function

Step 2: Find difference quotient

<u>Substitute:</u> $\frac{[-(x+h)^2-3(x+h)+1]-(-x^2-3x+1)}{h}$
<u>Expand and Distribute:</u> $\frac{[-(x^2+2hx+h^2)-3x-3h+1]+x^2+3x-1}{h}$
<u>Distribute:</u> $\frac{-x^2-2hx-h^2-3x-3h+1+x^2+3x-1}{h}$
<u>Combine like terms:</u> $\frac{-2hx-h^2-3h}{h}$
<u>Factor out </u><em><u>h</u></em><u>:</u> $\frac{h(-2x-h-3)}{h}$
<u>Simplify:</u> $-2x - h - 3$

in a farm 20% of animals are cows . 0.4 are goat and the rest are sheep.How many cows are there if there are 40 sheeps

Zolol [24]

Step-by-step explanation:

20%=cows 0.4(40%)=goat 40%=sheep

if 40%sheep=40 sheeps

20% cow=x

20%×40=40%×x

8=40%x

x=8/40%

x=20

..so there are 20 cows

sorry...not sure
