(x^7+5x^4-x+2)-(5x^4-x^3+2)
=x^7+5x^4-x+2-5x^4+x^3-2
Combining like terms
x^7+5x^4-5x^4+x^3-x+2-2
=x^7+x^3-x is your final answer. Hope it help!

Let f(x)=−12(x+2)2+5 . What is the average rate of change for the quadratic function from x=−3 to x = 1?

aev [14]

Answer:

Average rate of change = -6

Step-by-step explanation:

The average rate of change over the interval (a,b) is given by;

[ f(b) - f(a)] / (b-a)........................where interval is (a,b)

(a,b) interval =(-3,1)

Where;

f(x)= -12 (x+2)² +5

$f(a)=f(-3)=-12(-3+2)^2+5\\f(a)=f(-3)=-12(-1)^2+5\\f(a)=f(-3)=-12(1)+5\\=-12+5=-7\\\\\\f(b)=f(1)=-12(1+2)+5\\f(b)=f(1)=-12(3)+5\\=-36+5=-31\\\\f(b)-f(a)=-31--7=-24\\\\b-a=1--3=4\\\\f(b)-f(a)/b-a=\frac{-24}{4} =-6$

Jada has a rectangular garden that is 10 meters long and 20 meters wide. (1 meter = 39.37 inches) how long is the garden measure

Rina8888 [55]

I think the answer is if you multiply. 10m X 20w= 200, now if you devide 39.37 in 200 is equal to 5.08in

3. A jump rope is 9 feet long. How long is the jump 4<br> rope in yards?

Inessa05 [86]

The answer is 3 yards.

There are 3 feet in a yard, so if we divide 9 (the length of the rope in feet) by 3, then we get the amount of yards in the rope: 9/3=3.
